Chemical Hygiene Plan

The College of Engineering Chemical Hygiene Plan can be downloaded as a pdf or viewed on the webpage below.


The California State University Long Beach (CSULB) College of Engineering (COE) Chemical Hygiene Plan (CHP) has been designed to fulfill the Cal/OSHA requirement regarding "Occupational Exposure to Hazardous Chemicals in Laboratories," California Code of Regulations (CCR), Title 8, General Industry Safety Orders, Section 5191. The contents of this regulation and its appendices are available to employees at the COE Safety Office, ECS-620. These regulations mandate that where hazardous chemicals are used in the workplace, the employer shall develop and carry out the provisions of a written CHP which is:

  • Capable of protecting employees from the health hazards associated with hazardous chemicals present in the workplace
  • Capable of keeping exposures below Cal/OSHA-regulated limits
  • Readily accessible to employees via hard-copy at the COE Safety Office in ESC-620 and electronically on the COE website
  • Reviewed annually and updated, as appropriate.

This CHP, along with the following documents, constitutes the foundation of our employee Health and Safety Program.

Student health and safety are also covered by these policies and procedures where applicable. The information presented in the CHP represents best practices and provides a broad overview of the information necessary for the safe operation of laboratories that utilize potentially hazardous chemicals. It is not intended to be all inclusive.

5.1 COE Safety Policy

All members of the COE community are expected to be thoroughly familiar with their safety responsibilities, strive to follow safety practices at all times, act proactively to prevent accidents and injuries, communicate hazards to supervisors, and be prepared for emergencies that may occur in the workplace.

5.2 Project Review and Authorization Requirement

A Project Review and Authorization approval process is required to ensure COE faculty and staff projects meet COE and EH&S guidelines. This approval process ensures COE activities are conducted in compliance with local, state, and federal regulations.

COE requires the form in Appendix D to be completed for:

  • Startup of a new lab for a new faculty member
  • A project that generates hazardous waste, involves PHS, or involves specifically regulated activities listed on the project review form
  • A project that requires new equipment purchases (CHO will identify which project purchases require pre-approval
  • A project that involves a new process which has not been previously approved in COE.

When completing the Project Review and Authorization form please note the following items.

1. Chemicals: List the types of hazardous chemicals used in the project, including significant amounts of hazardous consumer products (gasoline, coatings, adhesives, resins). You may list chemicals by general type/class, but please list key “Extremely Hazardous” chemicals and all Cal/OSHA Regulated Carcinogens.

2. Physical Hazards: List hazardous equipment/operations associated with the project including: motor vehicle travel, climbing, open flames, U.V. light, hazardous lasers, high voltages, microwaves, radiation, plasmas, cryogenics, high pressures, dangerous animals, tools, centrifuges, autoclaves, etc.

3. Biological Hazards: List any pathogenic organisms involved in a project.  State if you intend to work with human tissues, blood or blood components.

4. Training Plan: Describe methods you will use to provide documented safety training related to the materials and methods employed in this project.  The CHO can support the development of safety training material.

5. Safety Procedures, Equipment, etc.: Briefly describe safety procedures and equipment that will be employed to protect personnel from the hazards. If necessary, refer to the COE CHO for guidance in these areas. Required use of fume hoods, protective clothing, spill prevention/control equipment, fire extinguishers, flammables cabinets, etc. are examples of protective equipment. A mandatory buddy system policy and requiring drivers to obtain a CSULB Defensive Driver's Certificate are examples of safety procedures.

6. Outreach Activities: Demonstrations during such events will put you in contact with the public and often minors. An extra level of safety must be introduced into such activities. Specific approval for each such project is required – and other forms/approvals must be obtained in advance. Contact COE CHO for details.

7. Hazardous Waste: Please indicate if this project will generate hazardous waste, e.g. chemicals, oil, batteries, sharps, etc.

Approval is granted only if appropriate SOPs, engineering controls, monitoring equipment, training and emergency procedures are in place.  Other requirements deemed appropriate by COE CHO must also be met.  In some instances, department chair, campus EH&S and/or Dean approval are required.

5.3Prior Approval of Laboratory Activities Requirement

Anyone who plans to use strictly regulated or hazardous chemicals (see Section 8.1) or conduct non-standard hazardous activities must obtain prior approval from COE CHO before starting work.  Materials which are extremely hazardous, reactive, require special monitoring equipment, or used in such a way that could subject the user to unhealthful levels of exposure would trigger this requirement.  Examples include, but are not limited to, the use of hydrofluoric acid, inhalation hazard gases, black powder, and perchloric acid.

Approval is granted only if appropriate SOPs, engineering controls, monitoring equipment, training and emergency procedures are in place. Other requirements deemed appropriate by COE CHO must also be met.  In some instances, department chair, campus EH&S, and/or Dean approval are required.

5.4 Measures to Reduce Hazardous Materials Exposure

Use of any hazardous chemical in COE laboratories requires:

1. An assessment as to whether chemical elimination or substitution if feasible
2. Development of appropriate engineering controls
3. Development of Safe-Work Practices
4. Development of administrative controls; and
5. Identification of any required PPE.  

Consideration of chemical types and potential exposure routes must be considered. SDSs shall be maintained by each laboratory supervisor and be readily available to all laboratory personnel. Engineering controls specified in SDSs and SOPs will be used to control level of exposure to the chemical in use. Examples of these engineering controls include, but are not limited to, chemical fume hoods, glove boxes, physical shields or barriers, local exhaust ventilation and biological safety cabinets. All chemicals that generate hazardous fumes, mists, or vapors shall be handled inside a properly functioning fume hood or other process enclosure.  

Voluntary use of dusk masks and respirators requires users to read and understand California Regulation 8 CCR 5144, Appendix D. The COE CHO shall document that a user had reviewed and understood Appendix D by having the voluntary user sign a form stating user acceptance of the conditions stated in Appendix D.

Laboratory personnel generally do not use personal respirators. Where the use of respirators is necessary to maintain exposure below permissible exposure limits (PELs), the COE CHO will evaluate and if deemed required, will then provide a respirator and the appropriate training to the individual. Respirators will be selected and used in accordance with the requirements of CCR Title 8, Section 5144. 

The following criteria will be used when determining any required control measures to reduce an employee’s occupational exposure:

1. Verbal information obtained from employees regarding chemical usage
2. Visual observations of chemical use or laboratory operations
3. Evaluation of existing engineering control measures or administrative practices
4. Any PI/Laboratory Supervisor, CHO, EH&S, and SDS recommendations
5. Cal/OSHA regulatory requirements
6. Recommendations from professional industrial hygiene organizations such as AIHA
7. Direct reading instrumentation results
8. Employee exposure monitoring results
9. Medical evaluation, examination and/or surveillance findings.

Particular attention will be given to the selection of safety control measures for chemicals that are known to be extremely hazardous (See section 8.4).

5.5 Safety Rules in Laboratories

The following safety rules need to be followed when working in a COE laboratory:

1. LOCK UP!  If YOU unlocked a room, never leave it unattended. If you leave a room that you unlocked, you could be held responsible if someone gets in and hurts themselves, steals, or damages items in that room in your absence. Nearly every room has expensive items and dangerous chemicals.  ALWAYS LOCK UP WHEN YOU LEAVE!
2. No food or drink are allowed in labs.  Smoking is not permitted at CSULB.
3. Follow safety instructions or warnings given by people who use the space.  If instructed to exit the premises, please do so.
4. Do not enter a room posted on the outside with a temporary sign stating, "KEEP OUT," "DANGER," or equivalent wording. Room conditions inside may be dangerous or sensitive requiring others to stay out for a period of time. The CHO and/or EH&S shall be notified of such conditions prior to posting. Contact the CHO or laboratory personnel for updated conditions.
5. When entering areas containing hazardous chemicals or hazardous equipment do not touch items on laboratory benches or in fume hoods. DO NOT PUT ANY TOOLS OR OTHER ITEMS ON LABORATORY BENCHES OR SINK AREAS THAT ARE MARKED WITH WARNING LABELS.
6. If equipment or chemicals are in the way of conducting a work task, ask either the PI/Lab Supervisor, or their designated person, to move them to a safe location. Do not move the chemicals yourself.
7. Always read warning signs and labels on items in the rooms, such as "Danger - High Voltage," "Corrosive," "Poison," "Flammable," "Oxidizer," etc. Do not touch these items and use extreme caution when working in the room.
8. Always read signs placed on trash cans in the rooms. Plastic, cardboard, and metal trash cans or baskets are sometimes used for special purposes. For example, some containers are used for the collection of broken glass. DON’T TOUCH containers used for the collection of biohazardous/Medical Waste (containers with RED bags and “Biohazard” labels).
NEVER THROW BROKEN GLASS OR SHARP ITEMS IN THE REGULAR TRASH. Use specially labeled boxes that are used to collect broken laboratory glass, etc., and are found in most labs. For custodians, if you see sharp items in the trash, do not touch them; leave them there and notify your supervisor.
9. Note the locations of eyewash/shower units as you enter the laboratories and observe how they work. Once turned on, they must be turned off by hand; turn off is NOT automatic. Knowing how they work can prevent a flood if a falling object accidentally turns one on. [DOWN = ON. UP = OFF].
Use this equipment if you get chemicals on your body or in your eyes,  either from accidents involving laboratory chemicals or from service chemicals such as corrosive cleaners, strippers, solvents, battery acid, etc. To use the shower or eyewash, turn it on and flush a contaminated body part for 15 minutes. The floor will flood as most units have no drains.  Your health is the most important thing.
Areas beneath eyewash/shower units MUST remain clear of boxes, trash cans, equipment or other items at all times. Do not place any items beneath eyewash/shower units that would block access during an emergency. Report any blocked units to your supervisor or the COE CHO.
10. NEVER clean up or touch a puddle of liquid unless it is OBVIOUSLY from a water leak (it could be acid or a poisonous chemical). Report suspicious spills to your supervisor.
11. Always check for natural gas problems when you enter a room. 
12. If an item is knocked over or there seems to be any problem with materials or equipment in a room (noise, smell, heat, smoke, etc.) please report it to your supervisor, the COE CHO or Facility Coordinator, and/or public safety. Use an emergency phone box or 911 from an office phone as necessary.

5.6 Employee Medical Consultation, Examinations, and Surveillance

If an employee has an adverse reaction to a hazardous chemical, then the following subsections may apply.

5.6.1 Medical Attention and Followup

The COE shall provide employees who work with hazardous materials an opportunity to receive medical attention, including any follow-up examinations which the examining physician determines to be necessary, under the following circumstances:

1. Whenever an employee develops signs or symptoms associated with a hazardous chemical to which the employee may have been exposed in the laboratory, the employee shall be provided an opportunity to receive an appropriate medical examination through the University’s Worker’s Compensation program.
2. Where exposure monitoring reveals an exposure level above the action level (or in the absence of an action level, the exposure limit) for a Cal/OSHA regulated substance for which there are exposure monitoring and medical surveillance requirements, medical surveillance shall be established for the affected employee as prescribed by the particular standard.
3. Whenever an event takes place in the work area such as a spill, leak, explosion or other occurrence resulting in the likelihood of a hazardous exposure, the affected employee shall be provided an opportunity for a medical consultation. Such consultation shall be for the purpose of determining the need for a medical examination.
4. All medical examinations and consultations shall be performed by or under the direct supervision of a licensed physician and shall be provided without cost to the employee, without loss of pay and at a reasonable time and place.
5. Information provided to the physician. The employer shall provide the following information to the physician:

  • The identity of the hazardous chemical(s) to which the employee may have been exposed;
  • A description of the conditions under which the exposure occurred including quantitative exposure data, if available; and
  • A description of the signs and symptoms of exposure that the employee is experiencing, if any.

5.6.2Physician’s Written Opinion

For a Physician’s examination or consultation of employees as required under 8 CCR 5191, the COE will obtain a written opinion from an examining physician that includes the following information:

  • Any recommendation for further medical followup.
  • The results of the medical examination and any associated tests, if requested by the employee
  • Any medical condition which may be revealed during the examination which may place the employee at increased risk as a result of exposure to a hazardous chemical found in the workplace
  • A statement that the employee has been informed by the physician of the results of the consultation or medical examination and any medical condition that may require further examination or treatment.

The written opinion cannot reveal specific findings of diagnoses unrelated to the occupational exposure.

5.6.3 Student Workers with Potential Adverse Health Effects from Hazardous Chemicals

Student laboratory workers who exhibit signs and symptoms of adverse health effects from a work-related exposure to a hazardous chemical should notify their immediate supervisor and then report to the Student Health Center or personal physician. Refer to the Injury and Illness Prevention Program (IIPP) for procedures on how to obtain medical evaluations.

5.6.4.Medical Surveillance

Medical surveillance is the process of using medical examinations, questionnaires and/or biological monitoring to determine potential changes in health as a result of exposure to a hazardous chemical or other hazards. Certain Cal/OSHA standards require clinical examination as part of medical surveillance when exposure monitoring exceeds an established Action Level or Permissible Exposure Level (LEL).

Occupational medical service providers will conduct medical surveillance services. Medical surveillance is required of employees who are routinely exposed to certain hazards as part of their job description (such as asbestos) and may be offered to other employees based upon quantifiable or measured exposure.

The following chemicals may be monitored through a medical surveillance program:

  • Asbestos
  • Benzene
  • Formaldehyde
  • Lead
  • Methylene Chloride, and
  • “Particularly Hazardous Substances.”

In addition, both noise (noise testing as specified in a Hearing Conservation Program) and respirator use (inhalation monitoring in Respirator Protection Program) can be monitored through a medical surveillance program when the respective programs are required.

5.7 Reproductive Health Policy

Male or female, you should never work with a chemical without knowing how it may affect the reproductive system, and the length of time the material could remain in your body if ingested, inhaled, or absorbed. The use of some agents should be stopped well in advance of conception.

Pregnant women and those who plan to become pregnant are strongly encouraged to consult their physician regarding the evaluation of workplace hazards as they relate to reproductive health and fertility. The physician should be provided with specific information regarding type of work, chemicals used, SOPs, and be provided SDS for all chemicals.

If working with other hazardous materials, you may find the following documents helpful:

  • NIOSH Pocket Guide to Chemical Hazards," from the U.S. Department of Health and Human Services
  • SDS online access (see COE CHO)

Please feel free to contact your supervisor, COE CHO, or EH&S with any further requests for information required by you or your physician regarding reproductive hazards in the workplace.

5.8 Fume Hood Requirements

5.8.1 Overview

Chemical fume hoods constitute an important safety resource for COE personnel. See Figure 1 for a standard fume hood diagram. Hoods are used instead of strap-on respirators to protect personnel from airborne chemical hazards. When used PROPERLY hoods provide protection from hazardous vapors, gases, fumes, mists, and dusts that may arise from the materials being handled.

General-use chemical fume hoods must be inspected/surveyed annually by the COE CHO or designee. The inspection/survey process consists of quantitative airflow measurement, qualitative inward airflow check, check of the permanent, quantitative, airflow indicator, label check, lighting check, noting special use/conditions, and certifying the inspection/survey label and data sheet. Any hood that fails the airflow tests must be immediately posted "Out of Service." The data sheets will then be reviewed by Safety personnel to generate a list for hood repairs and prioritizing the repairs with respect to employee/student safety.

Cal/OSHA mandates that the hood-inspection records (the completed data sheets generated by the process) be retained for FIVE YEARS. Original data sheets or similar documentation (computerized data) are retained in the COE Safety Office. Hoods must be re-surveyed after critical hardware has been changed or repaired (motor replacement, change in pulley size, etc.) or if inadequate performance is suspected (as evident by the airflow indicator).

5.8.2 Fume Hood Guidelines

General guidelines for the use of a chemical fume hood are listed below. All 12 considerations below MUST be understood and followed when using a hood to protect you from harmful concentrations of hazardous chemical (levels above the Cal/OSHA Threshold Limit Value).

Fume Hood
1. The unit must have passed a performance inspection by COE CHO within the past year. A sticker near the sash will indicate the most recent inspection date. Hoods that do not pass inspection are posted with a warning sign. These hoods MAY be used for "open bench" type operations that only generate nuisance levels of airborne contaminants. Do not use such a hood for protection as you WILL LIKELY BE EXPOSED to the material being handled.
2. A continuously operating airflow indicator must be present, operational and demonstrate proper airflow. Most COE hoods are equipped with Vane-o-meters shown below in Figure 2. Verify airflow is in excess of 100 LFM prior to each use.
3. Use the hood with the sash no higher than the mechanical stop or point indicated by the "arrow" stickers. Temporarily raising the sash above the arrow/stop position (to facilitate equipment or container movement) may not be done for more than a few minutes or when hazardous chemicals are in use. Keep the hood sash closed when not using the hood.
4. To ensure proper performance, minimize the amount of material inside the fume hood. An item as large as a basketball can cause an airflow “dead zone” preventing the hood from meeting proper airflow standards and allowing hazardous emissions out into the lab. All items in the hood should be no closer than 6 inches from the front airfoil. In addition, maintaining 1 inch of space between items and under large objects
helps ensure adequate airflow. If you place a large item inside the hood, call COE CHO for an airflow survey to ensure the airflow is still adequate.
5. Do not manipulate hazardous chemicals in a malfunctioning hood as you will be exposed to the material being handled. In the event of a hood failure or ventilation malfunction, STOP WORK IMMEDIATELY, close the hood sash and inform others in the room. Report any hood problems promptly to your supervisor, COE CHO, or campus EHS.
6. In the event of fire, close the sash (if safe to do so) and exit room. Do not push the Emergency Exhaust button! Use the hallway fire alarm as appropriate.
7. Do not use the hood to intentionally dispose of (evaporate) hazardous chemicals. Containers of volatile materials in the hood must be kept closed when not in use.
8. Hood use for a Cal/OSHA-regulated carcinogen requires more stringent standards.
9. Hoods should be cleaned periodically. Annual cleaning is recommended.
10. Hazardous waste containers in hoods must be inside a secondary container tray, tub, or bucket.
11. After addition of large items, the airflow must be re-surveyed.
12. Users may NEVER put their head into the hood.

5.8.3 Fume Hood Inspection Procedure

This hood check procedure is to be performed by trained personnel wearing appropriate PPE (ex., lab coat, goggles and disposable gloves). The inspector should minimize handling items inside the fume hood.  If an item in the hood obstructs airflow, the inspector is not obliged to move the offending item even if the item in question causes the hood to "fail" the airflow test.

If the hood fails due to inadequate air flow of 100 liters per minute (LPM), then the inspector should move the sash lower in an attempt to attain proper flow (no lower than the 12 inches minimum).

1. Label check:

Make sure that required Chemical Fume Hood Inspection sticker is in place. Re-label as needed.  Place the new label over the old one to minimize clutter. If an exhaust fan code or use label is present, make sure it is legible.

2. Airflow measurement:

a) Move sash to the "arrow" sash-height indicators if present or to the "hood stop" at the top.  Take readings at nine sample points (at least 1 inch from the opening perimeter) to determine if airflow is over 100 LPM. Rotate the measuring device (velometer, Vane-O-Meter, etc.) as needed to obtain the highest flow value. Do not block airflow with your body. Recall that items in the hood can create airflow zones of less than 70 LFM. If the averaged airflow is less than 100 LPM, the sash may be lowered until the average LFM meets the required threshold (note: 12-inch minimum opening).  If the sash opening has been changed, the arrow indicators must also be changed at this time.

b) To perform a qualitative airflow measurement using chemical smoke, slowly puff smoke across the face of the hood. The smoke must be pulled into the hood with any blowback of smoke being grounds for failure.

3. Airflow Indicator check using a Vane-o-meter:

a) This indicator must remain firmly attached, level and read accurately. Use a brush to clear dust from the device being careful not to disturb the fragile vane. If it is damaged, the vane must be replaced.

4. Hood lighting check:

a) Ensure that the fluorescent lights are functioning and record the results. Replace as needed.

Immediate response is required if the following events occur with a fume hood: 

a) If airflow is less than an averaged 100 LFM upon testing or if motor issues occur, post the hood with a "DO NOT USE; Inadequate Airflow" warning sign. Contact the COE CHO or Facilities to coordinate service for a hood.

b) If unsafe practices are encountered (unlabeled hazmat, incompatible chemicals, open containers, waste problems etc.) when attempting to test, contact the COE CHO who will coordinate with the responsible party, and the department chair to correct the issue.

5. Documentation/Recordkeeping:

a) If the unit passes, initial and date the hood inspection tag. If it fails, mark "FAILED" and the test date.

b) Complete the Hood Inspection Data Form and note any special problems in the "comments" section.

c) The COE CHO will prioritize the findings and coordinate repairs for problems as appropriate. The COE CHO will file the survey data sheets per the Cal/OSHA five-year record retention mandate.

5.9 Use of Risk and Safety Solutions (RSS) Software

COE CHO is coordinating the implementation of a chemical software system at COE which is designed to improve safety and facilitate regulatory compliance in campus laboratories where hazardous chemicals are used. The software was developed by the University of California Systems in order to implement risk management and safety tools. The software has been used extensively throughout UC campuses and medical centers and has been adopted by the California State University System for implementation. The software system is organized into the following three integrated modules.

5.9.1 Risk Assessment Module

This tool allows principal investigators to identify hazards related to their research and share this and other critical safety information about these hazards with the members of their lab. You can start your assessment today by signing into using your campus email and then entering your single sign-on information. A window will come up with the icons shown below and then click “Assessment”

5.9.2 Chemicals Management Module

A chemical inventory management tool will use a barcoding system to quickly add chemicals to an inventory. It includes a library of chemicals that are referenced to populate chemical details, like hazards and first aid information. The module is available in a phone app as well as for tablet or desktop.

5.9.3 Inspections Module 

A flexible, customized tool that manages the scheduling, completion and long-term tracking of safety inspections, it is available for phones, tablets, and desktops.

Implementation of this system at COE is required for all labs utilizing chemicals. For non-lab areas using chemicals such as a machine shop, the chemical inventory can be kept using MSDSonline. The COE CHO will assist with training and support during implementation of RSS.

Safety information is conveyed with the CSULB website, targeted emails, and through verbal communications and trainings. The following websites can be used to obtain safety information pertaining to COE and CSULB campus:

COE and CAL/OSHA require the development and use of Standard Operating Procedures (SOP) when dealing with hazardous materials and hazardous operations. An SOP is a written set of instructions that document how to safely perform hazardous work or processes to ensure that projects are conducted in a safe and consistent manner.

SOPs may focus on any of the following: Processes (e.g., novel nanomaterial synthesis, distillation, laser sintering) Hazardous chemicals (e.g., carbon monoxide, hydrofluoric acid) Class of hazardous chemicals (e.g., organic solvents, pyrophoric material, heavy metals)

An example SOP for concentrated mineral acids can be found in Appendix D. Sample chemical SOPs created by other educational institutions can be found here:

Alternative SOP formats are acceptable for lasers and other equipment or processes. The only requirement is that the SOP ensure a safe, predictable outcome when students, faculty, and staff are working with hazardous chemicals or conducting hazardous operations. SOPs shall be reviewed and approved by the COE CHO and/or EH&S.

Safe handling, use, and disposal of hazardous materials prevents injuries and incidents. Tracking of chemicals on campus will be performed through the RSS system for laboratories and the MSDSOonline system for non-lab spaces. Faculty are responsible for the inventory, storage, use, and disposal of any hazardous chemicals acquired by the personnel they supervise.

The following materials are currently restricted on campus: Cal/OSHA regulated carcinogens, Risk Group Level 3 or 4 biohazardous materials, explosives, DEA-regulated chemicals, human blood and blood products, and highly unstable/water reactive materials. Contact COE CHO for details. Personal transport of hazardous materials to CSULB or from CSULB to an offsite location must have approval from both the COE CHO and the EH&S Director.

8.1 Particularly Hazardous Substances (PHS)

Substances that pose significant threats to human health are classified as "particularly hazardous substances" (PHS). The OSHA Laboratory Standard and Cal/OSHA regulations require that special provisions be established to prevent the harmful exposure of researchers to PHS, including the establishment of designated areas for their use.

Particularly hazardous substances are divided into three primary types:

  • Acute Toxins
  • Reproductive Toxins
  • Carcinogens

8.1.1 Acute Toxins

Substances that have a high degree of acute toxicity are interpreted by Cal/OSHA as being substances that "may be fatal or cause damage to target organs as the result of a single exposure or exposures of short duration.” These types of chemicals, associated waste, and storage containers must be handled with care to prevent cross contamination of work areas and accidental contact. These chemicals must be appropriately labeled, and any empty containers must be triple-rinsed, with the rinsate discarded as hazardous waste. Waste rinsate shall not be disposed of into the sanitary sewer system.

8.1.2 Reproductive Toxins

Reproductive toxins include any chemical that may affect the reproductive capabilities, including chromosomal damage (mutations) and effects on fetuses (teratogenesis). Reproductive toxins can affect the reproductive health of both men and women if proper procedures and controls are not used. For women, exposure to reproductive toxins during pregnancy can cause adverse effects on the fetus; these effects include embryolethality (death of the fertilized egg, embryo or fetus), malformations (teratogenic effects), and postnatal functional defects. For men, exposure can lead to sterility.

Examples of embryotoxins include thalidomide and certain antibiotics such as tetracycline. Women of childbearing potential should note that embryo toxins have the greatest impact during the first trimester of pregnancy.

Because a woman often does not know that she is pregnant during this period of high susceptibility, special caution is advised when working with all chemicals, especially those rapidly absorbed through the skin (e.g., formamide).

Pregnant women and women intending to become pregnant should consult with their laboratory supervisor and their physician before working with substances that are suspected to be reproductive toxins.

8.1.3 Carcinogens

Carcinogens are chemical or physical agents that cause cancer. Generally, they are chronically toxic substances; that is, they cause damage after repeated or long-duration exposure, and their effects may only become evident after a long latency period. Chronic toxins are particularly insidious because they may have no immediately apparent harmful effects.

  • Select Carcinogens as defined in CCR Title 8 § 5191 include any substance regulated by Cal/OSHA as a carcinogen, any substance listed under the category “known to be carcinogens” in the Annual Report on Carcinogens published by the National Toxicology Program (NTP), any substance listed under Group 1 (“carcinogenic to humans”) by the International Agency for Research on Cancer Monographs (IARC) (Volumes 1-48 and Supplements 1-8); or any substance listed in either Group 2A or 2B by IARC or under the category, “reasonably anticipated to be carcinogens” by NTP.
  • Regulated Carcinogens are those select carcinogens regulated by Cal/OSHA as carcinogens and fall into a higher hazard class and have extensive additional requirements associated with them. The use of these agents may require personal exposure sampling based on usage. When working with Regulated Carcinogens, it is particularly important to review and effectively apply engineering and administrative safety controls as the regulatory requirements for laboratories that may exceed long term (8 hour) or short term (15 minutes) threshold values for these chemicals are very extensive. Approval must be granted by COE CHO prior to commencing work with this class of chemicals.
  • Listed Carcinogens are a special subset of Regulated Carcinogens and are listed in CCR Title 8 § 5209. The use of these materials is strictly regulated and must be registered with COE CHO and Campus EH&S.

8.2 Designated Areas for PHS

Designated area(s) for use of particularly hazardous substances must be formally established by developing SOPs and posting appropriate signage. This designated area(s) may be an entire laboratory, a specific work bench, or a chemical fume hood. When particularly hazardous substances are in use, access to the designated area shall be limited to personnel following appropriate procedures and who are trained in working with these chemicals.

Access to areas where particularly hazardous substances are used or stored must be controlled by trained employees. Working quantities of particularly hazardous substances should be kept as small as practical and their use should be physically contained as much as possible, usually within a laboratory fume hood or glove box. It is the responsibility of each Principal Investigator, or their designee, to train and authorize their staff for these operations and to maintain documentation of this training and authorization.

Signage is required for all containers, designated work areas and storage locations. The signage must state the following as appropriate for the specific chemical hazard: “DANGER – (CHEMICAL IDENTIFICATION) – MAY CAUSE CANCER”

Entrances to designated work areas and storage locations of Listed Carcinogens must also include signage stating “AUTHORIZED PERSONNEL ONLY.” Work surfaces should be stainless steel, plastic trays, dry absorbent plastic-backed paper, chemically- resistant epoxy surfaces, or other chemically impervious material.

Protocols, procedures, and experiments must be designed and performed in a manner to safely maintain control of the particularly hazardous substances. Laboratory personnel must specifically consult with their PIs if a special hazard is involved (e.g., material under pressure) or if they are uncertain of the potential hazards.

8.3 Personal Protective Equipment(PPE)

PPE must be sufficient to protect eyes and skin from contact with the hazardous agents. Chemical splash goggles, lab coat, long pants, closed toe shoes, and gloves are required when working with PHSs. Flame-resistant lab coats may be required if the chemicals being used are flammable or when handling pyrophoric chemicals outside of a glove box.

Refer to the specific chemical’s SDS and SOP for specific information on additional PPE and glove selection. Contaminated PPE and clothing must be disposed of as hazardous waste.

8.4 Engineering Controls for PHS

Benchtop work with PHS is prohibited. Containment systems (such as fume hoods or glove boxes) must be used. Laboratories and rooms where PHS are used must have local exhaust ventilation such as chemical fume hoods or be used/stored in glove boxes for containment purposes. Air from these ventilation systems must be vented externally; recirculation is not permitted. Doors providing access from public areas must be kept closed.

8.5 Special Handling and Storage Requirements

Particularly hazardous substances must be stored in a designated area and used in a manner that will minimize the risk of accidental release (e.g., capped tightly, use of chemical resistant secondary containment, whenever possible). Laboratory personnel should remove chemicals from storage only as needed and return them to storage as soon as practical.

Chemicals should be segregated from incompatible materials, as described in the COE General Safety Awareness Training Presentation. The use of PHS must be confined to an established designated area.

Additional requirements for the safe storage of a specific chemical may be found in the manufacturer’s instructions or in the SDS. When transporting chemicals beyond the immediate laboratory environment, containers should be protected from breakage by using a bottle carrier or other effective containment.

Contact COE CHO for guidance on the planned use of chemicals that may require further controls.

8.6 General Chemical Spill

In the event of a hazardous materials spill, the following procedures should be conducted. If it is an inhalation hazard, extremely hazardous, or you don’t know what it is, warn people and vacate the premises. Inform everyone who may be in danger that there is a spill, and to leave the danger zone immediately. Close the area doors and contact University Police via callbox/911 or pull the building fire alarm if area evacuation is necessary.

Call COE CHO or EH&S to report the spill. Section 1.1 for contact information. Request assistance as needed.

Identify the spilled chemical if safe to do so. If you do not know its hazards (flammable, corrosive, poison etc.), FIND OUT NOW. Ask someone who works with the chemical or Issue Room/Safety people and/or read the SDS BEFORE proceeding. Even a few grams or milliliters of some materials pose an inhalation hazard and must only be cleaned up by professionals wearing self-contained breathing gear and HAZMAT suits.

Spill cleanup: If it is safe to remain in the room, you know an overexposure is not possible, the spill is smaller than 1 liter/500gm, and you are capable of safely cleaning it up yourself, proceed as follows (stop if you feel affected by exposure):

1) If spilled material is flammable, extinguish all sources of heat and keep sparks away.
2) Keep people away from the spill.
3) Put on fully enclosed chemical splash goggles.
4) Put on two pair of gloves; check glove chart to be sure of protection from the chemical.
5) Stop the flow of the spill and utilize absorbent materials, pads, or pillows. Do not use paper towels unless the spill is very small and not an oxidizer.
6) Carefully place soaked materials into a compatible bag/container that can be sealed.
7) Put the closed container in a hood. Label it with a yellow “Hazardous Waste Label.”
8) Decontaminate surfaces/tools promptly. Use an appropriate cleaning agent. Contaminated cleanup materials go in the waste container too. If in doubt, contact EH&S, who will perform the clean-up.

In the event of direct skin contact with a particularly hazardous substance, the affected person must shower or flush the affected areas for a minimum of 15 minutes. Emergency eyewash stations should be used to more effectively flush eyes or other mucous membranes when involved.

Complete an INCIDENT REPORT form (attained by the COE CHO). Alternately call/visit COE CHO and relay what happened.

8.6.1 Acid Spills

For acid spills, call COE CHO for an acid spill kit if not readily available at your location. The following are instructions for a spill cleanup of a small (< 50 ml) release in a chemical fume hood:

Warn others and isolate the spill by closing the hood sash. Make sure you are wearing acid-resistant gloves, chemical splash goggles lab coat, Tyvek suit/sleeves or other appropriate protective clothing. Proceed with cleanup by placing an absorbent pad on the spill to contain the liquid. Remove acid pad and place into plastic zip-lock bag. Sprinkle acid neutralizer around perimeter of spill, then cover spill completely with neutralizer. Heat will be generated as neutralization occurs. The absorbent pad should have soaked up much of the liquid, so you are neutralizing the residue such that the hood may be safely used again. Stir with plastic scraper to increase neutralization effect. Wait at least 20 minutes for mixture to cool.

After 20 minutes, scoop up neutralizer/acid mix and place in plastic Ziplock bag for disposal. Use acid pads for further cleaning as necessary. Fill out yellow waste label and place on plastic bag. Call COE CHO for waste pickup. Confirm surface pH is neutral using test strip and small amount of water. Contact COE CHO or campus EH&S to report larger spills, spills outside the chemical fume hood or if you are incapable of performing or have not received training in this procedure.

8.7 Routine Decontamination Procedures

To limit the spread of contamination, laboratory work surfaces should be decontaminated at the conclusion of each procedure and at the end of each day on which PHS are used.

All equipment should be decontaminated before removing it from the designated area; this decontamination should be carried out in a glove box or fume hood where practical.

Contaminated PPE must not be removed from the designated area until properly decontaminated; after working with these chemicals, gloves must immediately be removed and disposed of as hazardous waste and hands and arms washed with soap and water. Contaminated PPE shall be bagged and sealed in polypropylene or other impermeable container and labeled.

8.8 Regulated Carcinogens and Report of Use Requirements

Regulated Carcinogens are a specific subset of select carcinogens which have special additional requirements associated with their use under certain circumstances. Every effort should be made to keep exposure levels below regulatory threshold limits by using engineering and administrative controls, appropriate PPE and following customized SOPs designed to reduce exposure. If exposures cannot be kept below regulatory thresholds, work shall cease until measures can be put in place to reduce exposure to acceptable levels. Before work may resume, additional requirements may include:

  • Required medical evaluations.
  • Additional documented training.
  • Use of respirators with required initial and ongoing training, medical evaluations, and maintenance documentation.
  • Additional documented hazard evaluations.

Listed Carcinogens are a further subset of regulated carcinogens. A list of these compounds can be found in CCR title 8 section 5209 (e) (1) (D). An evaluation will be completed to assess safety requirements for groups that use these materials.

Report of Use Requirements must be met for each group when they:

  • Begin the use of, or make significant changes to, existing use of any Listed Carcinogen.
  • Use Regulated Carcinogens such that there is a reasonable expectation that exposure limits may be exceeded.
  • Occur during an emergency in which employees have been exposed to any Regulated Carcinogen.

Whenever a chemical is taken from its original container, a secondary label is affixed to the new container to identify contents and any relevant hazards. The standard COE label is shown below and uses a DOT (Department of Transportation) based container labeling scheme with the addition of GHS pictograms.

hazardous labeling
These labels are available from your COE CHO. Label any unattended container of material as follows:
  • Product ID: Use the full name. Do NOT use abbreviations such as ETOH. Instead write the full name Ethanol. Hazard Statement: Write the hazard word shown below that was on the original container. Place a check mark on the appropriate symbol.
  • Make sure any old, inappropriate labels are completely unreadable (you may erase, deface, or remove labels).
  • Permanently labeled bottles may not be used for a different material (your label may fall off or your ink may wash off to show the old wrong label).

9.1 Container Labeling Addendum

GHS pictogram
The College of Engineering material label system is designed to indicate the identity and hazards of any given material. In the case of hazardous chemicals, the PRIMARY safety hazard(s) for that substance is indicated, as designated by GHS, federal/state codes or scientific literature. The information contained in this guide is intended to be an addendum to “secondary container” labels created by college personnel. This official label supplement is to be posted on the Official CAL/OSHA Workplace Safety Bulletin Board. All unattended containers must be marked. Notify the person in charge of your area or COE Safety Office if you encounter unlabeled/inadequately labels containers or unlabeled bulk/loose material.

Material Labeling Program Supplementary Information

1. Treat materials that bear any hazard warning as toxic.
Avoid inhalation, skin contact, and contamination of surfaces. Do not mix or store them with other materials unless you know the reactive properties.
Employees and students are required to know the hazardous properties of each material they handle.
2. Any properly labeled material may have additional hazardous properties.
The safety-trained faculty or staff person in charge of your workplace will be able to provide more specific chemical safety information (as is contained in Safety Data Sheets (SDSs) and other sources).

  • Toxic effects of chemicals are varied. Materials marked “POISON,” for example, may be toxic through very different mechanisms. Route of entry, exposure time, temperature, your physical condition, etc. all influence toxic effects.
  • Target organ. Many toxic agents focus on specific tissue, organs, or organ systems. The affected organ can be remote from the point of exposure. The eye, for example, can be affected from skin exposure to methanol.

3. Compatibility cannot always be determined by the hazard label.
While hazard labels indicate the gross hazard class, do not assume that all materials of the same hazard class are compatible (e.g. acids and bases are both labeled as corrosive). Refer directly to SDS-type information or to the College employee in charge of the area.
4. Spills of hazardous chemicals must be handled by qualified persons.
Contact COE CHO or call Campus EHS if you have ANY DOUBT about the severity of a chemical spill. Even a few milliliters or milligrams of some materials require trained persons using self-contained breathing equipment to avoid overexposure.
5. The college labeling procedure is written and is on the COE Safety website.
College employees and many laboratory students have been instructed in proper labeling as part of their introductory safety training. The details for the label system are among the official “Right-to- Know”/“Hazard Communication procedures” adopted by the College and/or University.

Hazardous wastes generated in the laboratories must be handled, labeled, and properly stored according to California regulations (22 CCR 66262) prior to removal by Campus EH&S.

10.1 Control of Waste-Producing Operations

Faculty (course coordinators, thesis advisors, principal investigators, etc.), staff (technicians, trades persons, supervisors, researchers, etc.) and administrators (program directors, deans, chairs) must anticipate and prepare for the responsible management of any hazardous waste generated from the campus activities they perform and/or oversee. Cal/OSHA has strict requirements regarding who may handle hazardous waste; you and your personnel may handle ONLY the waste generated by yourselves at your own worksite (usually a lab).

This written procedure is designed to help campus personnel fulfill this obligation. Nearly any use of a hazardous chemical can generate hazardous waste. Regulated hazardous waste can be created from “non-hazardous” materials. When hazardous waste must be produced, COE CHO will assist in the development of a process-specific plan to ensure safety and regulatory compliance. If possible, a non-hazardous or less-hazardous option will be proposed.

10.1.1 Generation Point Hazardous Waste Containers

Selection of an appropriate container or containers to hold the waste routinely generated by workplace operations is a critical step. If in doubt, contact COE CHO/Facilities at 5-8746 or EH&S at 5-2283 for details.

Sound, intact containers, appropriate for the waste, may be used over and over again for the same waste stream (emptied by specifically trained personnel into larger waste containers and then returned to the generation site) or they may be one-use containers (the disposition of unwanted emptied waste containers is the responsibility of the hazardous waste contractor). The following container selection/use guidelines must be observed at all times:

a. Container material: The container must be compatible with the waste, i.e. No acids in steel containers, no gasoline in Styrofoam, no picric acid or perchloric acid solutions in lead soldered or zinc-coated containers. No food or drink containers may be used.
b. Container condition: The container must be in sound condition including the closure(s) and gasket(s) as appropriate. No brittle, degraded plastics, structurally corroded metal, etc.
c. Container closure: The container must be equipped with a leak proof mechanical closure such as a threaded cap. The cap must be equipped with a gasket that contains the material when being carried or if it is tipped over. Cap threads must match the container. Friction fit stoppers or film seals are unacceptable.
d. Container size: Whenever possible, the container size should be matched to the volume of waste generated within 6 months. 100 ml of waste liquid in a 5-liter bottle can be a very wasteful situation as some waste contractors simply place the bottle in a drum rather than transfer/consolidate the material. Always leave room in the full container to allow for expansion. In the case of extremely hazardous chemicals; however, a small volume, including an un-rinsed "empty" container, can be an acceptable waste item.
e. Container spill control: Hazardous waste containers shall be stored in secondary containment. Fume hoods themselves do not function as secondary containment units. Secondary containment units are often available at no cost through the COE CHO.

10.1.2 Required Labeling for Hazardous Waste Containers

State and federal EPA regulations are very strict as to the labeling of hazardous waste. Never write the word “WASTE” on any container. For this reason, self-adhesive EPA-compliant Hazardous Waste Labels, shown below, are distributed by the CHO to COE faculty and staff.

hazardous waste label
The generator information on the label must be legibly completed by lab/workplace personnel at the time the label is affixed (see detailed instructions below as points a through e). If using an empty chemical bottle for waste, remove or deface all conflicting information on the old container label.

The person who sets up the waste collection container must write in information by hand, check boxes and circle categories to complete the label. Completely spell out waste components, do not use abbreviations. Waste identification must be understood by non-science personnel, including custodians and trades.

When waste containers are too small for the COE Hazardous Waste label, put the completed label on a 4 mil reclosable bag, add containers to bag, and zip closed. Bags are available from COE CHO. Contact the department issue room or the COE CHO for more information regarding the data required on the label or any other waste related question.

Instructions for Completing the Hazardous Waste Label: Please have a label in your hand as your read this information.

1. Start date: The date waste was first placed in the container or date the material was designated as waste must be indicated. Mark the date directly on the label. IN NO CASE MAY GENERATION POINT WASTE BE ACCUMULATED FOR MORE THAN NINE MONTHS -- EVEN IF THE CONTAINER IS NOT YET FULL. Request a pickup by notifying the COE CHO when the waste is six months old. This will prevent the risk of costly fines by regulatory agencies.
2. Name/identity of the waste material: The box marked “This container is to be used for the collection of:” requires a general name for the waste. This name must, where possible, be a recognized chemical or product name (such as "toluene" or "pump oil"). When the waste consists of a mixture of materials (such as "halogenated solvents", "animal preservative", or "HPLC waste") each component of the mix must be listed, and the approximate percent of the total mixture volume indicated. If the mixture contains more than 10 components, write the other components on an attached sheet. For example:
This container is to be used for the collection of: “Mixed solvents"
Components: "acetone 60%”, “isopropanol 5%”, “chloroform 5%”, “water 30%"
Below the “This container” box, circle the properties that apply to the waste. In the case of this example, circle “Solvents (non-halogenated)” and “Solvents (Halogenated).”
3. Physical state: Check the box to indicate Solid, Liquid or Gas. This MUST be done -- even if the waste is in a clear bottle and the physical state is obvious.
4. Hazard(s): Check appropriate box to indicate if Flammable, Oxidizer, Corrosive, Poison, etc., as appropriate. Hazard information may be taken from the original product label, ask the CHO (hazards assigned per DOT: 49CFR Sect. 172.101). For Flammable, Poison and perhaps Carcinogen would be appropriate. 5. Contents: As discussed in Item 2 above, use these 10 spaces to list the Components and Amount in % of the waste.
6. Faculty or staff name: The name of the faculty, staff or administrator responsible for the contents and oversight of the waste container must be indicated on the label. Please note that official responsibility for effective, ongoing oversight of a waste generating operation cannot be delegated to a student. The person listed is responsible for ensuring compliance and conveying these hazardous waste guidelines to everyone who generates waste. Having a person’s name on the label also facilitates timely return of re-usable waste containers.
7. DEPT (Department): Write in the department responsible. It may be an academic department, College, trades group (ex., Paint Shop, Auto Shop, Grounds, etc.), Animal Facility, etc. The department that acquired the original material is typically the group responsible for the waste created by its use. 8. Room #: List the room/location where the waste was created. Only waste generated on the CSULB campus may be managed by the CSULB program. Transport of waste to the campus from elsewhere is prohibited.
9. Acc. Fac. S.D.: Generators do not use this box. Campus Safety personnel indicate here when a full container has been moved to an approved on-campus storage area.

10.1.3 Generation Site Waste Management Practices

The faculty and/or staff considered responsible for a given waste-generating process should regularly examine the container(s) and monitor compliance. The responsible person must ensure that:

  • All persons adding waste are trained in waste compatibility and policies
  • All material added to the container is chemically compatible
  • Hazardous waste is collected -- not dumped in a sink or trash can
  • The container is sound and compatible with the waste
  • The container is kept closed at all times, except when adding waste
  • The container is kept in a containment tub, tray or other type of secondary containment
  • The container, label and any log sheet list contents and amount.
  • Any spills are dealt with promptly.
  • The COE CHO is notified when (1) The container is full, or (2) The six-month anniversary date (from first use) is approached, whichever comes first.

All laboratory personnel who work with or may be exposed to particularly hazardous substances (PHS) must be provided laboratory-specific training and information by the PI or their designee prior to beginning their initial assignment. Laboratory-specific training should cover specific policies and procedures, SOPs, etc. and is in addition to the basics covered in the General Safety Awareness Training presentation. Records of laboratory-specific training must be maintained in the laboratory and should include an outline of the topics covered. It is recommended that training documentation be maintained in Laboratory Safety Notebook.

Training shall include:

  • The hazards/toxicological effects associated with the chemicals being used.
  • Routine procedures and decontamination methods.
  • Emergency response practices and procedures.
  • Methods and observations for detecting the presence or release of hazardous chemicals.
  • Available protection measures, including engineering controls, appropriate work practices and (PPE).
  • A review of written SOPs, SDSs and the CHP.
  • A review of applicable policies.

Annual refresher training is required for particularly hazardous substances. Also, whenever there is a change in process, procedure or equipment training is required to update affected lab personnel. Written records must be maintained for each training session and stored in the EHS-managed Share Drive.


Labs shall be locked outside of normal work hours (7 a.m. to 5 p.m. Monday through Friday) and when unoccupied. Laboratory supervisors will determine the policy of locking doors during normal working hours.

Entry to all research (non-teaching) labs in the COE is restricted to trained, authorized key holders and other individuals authorized by the faculty in charge. Escorted guests with appropriate training or advisement may be allowed into a lab by the laboratory supervisor, appropriate administrator, or staff member in charge.

Supervising faculty/staff shall create a list of authorized individuals (see Appendix A). This list is to be posted on the interior of the laboratory entry door(s) and shall be updated as safety-trained personnel join or leave the lab.

After-hours work (i.e., Saturday/Sunday 8 a.m.-10 p.m. and Monday through Friday 5-10 p.m.) requires permission from the laboratory supervisor. Hazardous work, as determined by the laboratory supervisor and COE CHO, requires approval by the appropriate COE Chair (See Table 1.1).

Students (graduate and undergraduate) may never work alone in the laboratory outside of normal work hours. COE requires a minimum of two people in a lab when working after hours to ensure help can be called if one person has a medical emergency.

Key holders are responsible for the security of their keys. Keys shall remain on their person or otherwise secure when working in lab. Keys are not to be left on tables, desks, benches, or other areas in plain sight. Loaning of state keys is strictly regulated by California Penal Code 469. Keys to common-use areas shall be stored out of sight in secure locations within labs.

If an unauthorized individual gains access to your lab, inform them of the security policy and politely ask them to leave the lab. If needed, call Campus Police 911. Do not place yourself in danger by aggressively confronting unauthorized people. Let the police handle it.


This plan is to be reviewed annually and the following change log details updates that occur to the plan.  Reviews will be coordinated by the COE CHO and incorporate input from COE Dean, Associate Deans, Faculty Safety Committee, and COE Facilities Coordinator.
