Laboratory Chemical Safety · v1.0.0 · October 22, 2026
Course developed by Todd Jerome Jenkins, MS, CSP.
Learn to recognize chemical hazards and use the lab’s safety plan. Covers hoods, PPE, storage, exposure checks and emergencies. Fourteen audible lessons; allow about 45–60 minutes.
Online knowledge component only. Actual Chemical Hygiene Plan instruction, chemical- and task-specific training, equipment checks and employer verification remain separate. This course does not designate a Chemical Hygiene Officer or provide blanket laboratory, biosafety, radiation, hazardous-waste, shipping or emergency-response qualification.
1. Know when the Laboratory Standard applies
By the end: Identify the employer’s scope decision and the separate requirements for your assigned laboratory work.
The Laboratory Standard, 1910.1450, protects employees who may be exposed during laboratory use of hazardous chemicals. A room called a lab does not automatically meet its scope. The employer must examine the actual work. Laboratory scale means containers can be safely handled by one person; it does not mean any small production batch qualifies.
The definition of laboratory use has four conditions. Work is on a laboratory scale, multiple chemicals or procedures are used, the procedures are not part of or simulations of production, and protective laboratory practices and equipment are available and commonly used. Production work in a laboratory may instead fall under the relevant chemical-specific standards. Uses with no potential employee exposure are also outside this rule’s scope.
Where the standard applies, its relationship to other Subpart Z health standards has exceptions. Applicable exposure limits remain in force, as do specified prohibitions on eye and skin contact. Certain monitoring and medical-surveillance duties apply when the stated conditions are met. Other applicable safety requirements are not erased by calling the work laboratory research.
This course provides general chemical-safety knowledge. It does not qualify a person for every experiment, designate a Chemical Hygiene Officer or provide biosafety, radiation, shipping or emergency-response qualifications. Appendix A offers non-mandatory guidance; it does not add duties by itself. The employer must provide training and controls for the actual lab, chemicals and tasks.
Basis: 29 CFR 1910.1450(a)-(b), (l)
2. Use the Chemical Hygiene Plan
By the end: Locate the current CHP, Chemical Hygiene Officer and prior-approval process before starting assigned work.
The employer must develop and carry out a written Chemical Hygiene Plan, or CHP, for covered laboratory work. It must protect workers from chemical health hazards and keep exposure below applicable limits. A template in a binder is not enough if the lab does not use its procedures and controls. The plan must be readily available to employees and their representatives.
The CHP must include relevant safe operating procedures, criteria for choosing controls, and measures to ensure that hoods and other protective equipment work properly. It must address employee information and training, activities needing prior approval, medical consultation and examinations, responsible personnel and additional protection for particularly hazardous substances.
The employer designates a Chemical Hygiene Officer qualified by training or experience to give technical guidance on developing and carrying out the CHP. A committee is established if appropriate. Completing this course alone does not establish that qualification or transfer the employer’s responsibilities to a worker.
The employer must review and evaluate the plan’s effectiveness at least annually and update it as needed. New work, failed controls and lessons from incidents may reveal a need for changes sooner. Learn where the current plan is located, who can answer questions and how to report gaps. Verify that the plan matches the chemicals, equipment and tasks in your actual work area.
Basis: 29 CFR 1910.1450(b), (e)
3. Receive the right information at the right time
By the end: Identify the new-exposure training trigger and demonstrate where the required lab information is found.
Employees must receive information and training on the chemical hazards in their work area. Information is due at initial assignment where hazardous chemicals are present and before assignments involving new exposure situations. The employer determines refresher frequency. This standard does not set a universal annual retraining schedule or a fixed number of course hours.
Workers must know the contents and availability of the standard and appendices, where to find the CHP, relevant OSHA exposure limits and recommended limits where no OSHA limit applies. They also need information on signs and symptoms linked to the lab’s chemicals and where to find references for hazards, handling, storage and disposal, including supplier SDSs.
Training must cover ways to detect a chemical’s presence or release, the physical and health hazards, and protective measures. These include the employer’s actual work practices, emergency procedures and PPE. Training must also cover the applicable details of the written CHP. A general course cannot identify every local alarm, approval or procedure.
Ask questions and use teach-back to explain what you will do. Safe observation or practice can help the employer verify that you can apply the instructions. The worksheets support that process; the standard’s information-and-training paragraph does not prescribe one universal certificate format. Keep actual lab instruction separate from the online score and resolve gaps before relying on the training.
Basis: 29 CFR 1910.1450(f)
4. Read hazard information before exposure
By the end: Use the actual label and SDS to explain exposure routes, hazards, controls and missing information.
Chemicals can enter the body through breathing, skin or eye contact, swallowing or puncture. Some effects occur quickly; others develop after repeated exposure or a delay. Health hazards can include burns, irritation, sensitization, organ effects, cancer or reproductive harm. Physical hazards include fire, pressure and reactive behavior. Small quantity does not mean no risk.
Read the label and the SDS for the actual product and concentration. Find hazard identification, exposure controls, safe handling, storage, incompatibilities and emergency information. Review the planned conditions too: heating, mixing, pressure or changes in form may change the hazard. An SDS describes the product; it does not measure exposure during your task.
The employer must ensure incoming hazardous-chemical labels are not removed or defaced. Supplier SDSs received with shipments must be kept and readily accessible to lab employees. Identify transferred materials under the lab’s CHP and applicable labeling system. An abbreviation that only one person understands is a weak way to communicate hazards.
Do not taste or deliberately smell an unknown substance to identify it. Appearance and odor cannot prove safety. If identity or reliable hazard information is missing, keep the material out of use and notify the responsible person. Determine the actual hazards and controls before handling it rather than assuming it is harmless.
Basis: 29 CFR 1910.1450(f)(3)-(4), (h)(1)
5. Plan procedures and obtain required approval
By the end: Complete a task review and obtain the CHP’s required approval before a new or changed operation.
Review a procedure before starting it. Identify the chemicals, quantities, concentrations, equipment, energy sources and expected products or byproducts. Consider setup, transfer, reaction, shutdown, cleaning and waste. Ask what could go wrong and how that would affect you, coworkers and nearby operations.
The CHP must identify activities that require prior approval from the employer or a designee. Know the local triggers. New materials, unfamiliar equipment, unattended work or a change in scale can require additional review under the plan. A small successful trial does not establish that a larger reaction is safe. Heat removal, gas production and containment may change with scale.
Select controls before exposure. Consider safer materials or methods, containment, ventilation, work practices and suitable PPE. Substitutes need their own hazard review. Check that controls are compatible with each other and with the actual experiment. Do not use a standard procedure beyond the conditions for which it was reviewed.
Appendix A recommends risk assessment and additional precautions for scale-up; those recommendations support the binding CHP duties. Use the approved procedure and stop criteria, and arrange the needed supervision or assistance. If information is missing or the work changes, pause the affected task and obtain review rather than improvising a new method at the bench.
Basis: 29 CFR 1910.1450(e)(3)(i)-(ii), (v); Appendix A guidance
6. Verify hoods and other protective equipment
By the end: Identify the hood’s approved use, performance check and failure response before handling chemicals.
The CHP must require fume hoods and other protective equipment to function properly and specify how adequate performance will be ensured. A running fan or an open sash does not prove containment. Learn the checks, approved sash position, status indicators and failure response for the actual hood and task.
Use the equipment as instructed. Keep airflow paths clear and arrange apparatus according to the approved method. Keep your head outside the hood enclosure during chemical handling. Do not defeat alarms or alter the sash to fit an unreviewed setup. Large equipment, stored bottles and nearby airflow changes can interfere with performance.
Different enclosures are designed for different hazards. Do not assume a clean bench, biological safety cabinet or any enclosure with a fan is suitable for chemical vapors. Obtain confirmation from the lab’s responsible technical personnel that the chosen containment is approved for the substance and operation. Highly reactive or unusual tasks may need special systems.
If a hood alarm sounds or ventilation fails, follow the trained safe shutdown and emergency procedure. Stop affected exposure, notify the responsible person and prevent unapproved reuse. Appendix A advises routine maintenance and testing and warns against waste disposal by evaporation in a hood. A hood is an exposure control, not permission to release chemical waste.
Basis: 29 CFR 1910.1450(e)(3)(iii); Appendix A ventilation guidance
7. Match PPE and hygiene practices to the task
By the end: Explain the selected PPE’s limits and demonstrate the lab’s safe use and contamination-control practices.
PPE must match the actual exposure and task. Eye protection, gloves and protective clothing are not interchangeable. Select gloves using chemical compatibility, concentration, contact time and manufacturer information. A glove that looks intact may not protect against every chemical, and one material is not suitable for all lab work.
Use the employer’s hazard assessment and task instructions to choose eye and face protection. Where a face shield is needed, it does not replace the appropriate primary eye protection. Select clothing for the chemical and physical hazards, including any fire or splash risk. Inspect PPE, understand its limits and replace or manage contaminated items as instructed.
Keep chemicals away from food, drink and personal items. Do not mouth-pipette. Remove contaminated gloves before touching clean shared surfaces, and follow the lab’s handwashing and clothing-removal procedures. Appendix A supports these hygiene practices. Do not carry contamination into offices, eating areas or vehicles.
Where respirators are necessary to keep exposure below permissible limits, the employer must supply proper equipment at no cost and follow 1910.134. Required use involves the applicable program, medical evaluation, fit testing and training. A dust mask or borrowed respirator is not a substitute for failed ventilation. This course does not provide respirator clearance, fit testing or authorization.
Basis: 29 CFR 1910.1450(e)(3)(ii), (f)(4), (i); 1910.132, 1910.133, 1910.134; Appendix A guidance
8. Store and move chemicals safely
By the end: Check chemical compatibility, container condition, storage equipment and the approved transport method.
Plan storage before receiving a chemical. Know its identity, hazards, temperature needs and incompatibilities. Appendix A recommends separating chemicals by hazard and compatibility. Alphabetical order alone can place incompatible substances together. Follow the CHP, product information and applicable storage requirements for the actual chemicals.
Use suitable containers, cabinets and secondary containment. Keep access and exits clear. Do not use a working hood as general chemical storage when that interferes with its purpose. Chemicals needing cold storage require equipment suitable for their hazards; an ordinary food refrigerator is not a safe default for flammable chemicals. Keep food and beverages separate from laboratory chemicals.
Manage aging or unstable materials under specific procedures. Peroxide-forming, air-sensitive and water-reactive chemicals can require special inventory, dating, storage and disposal controls. Do not open, move or test a suspect unstable container on your own. Restrict access and contact the responsible chemical-safety personnel for an evaluated response.
For internal transport, use suitable carriers and containment and a route that limits collisions and public exposure. Secure compressed-gas cylinders and use their approved handling arrangements. This overview does not provide technical cylinder procedures or dangerous-goods shipping training. A bottle safe to use at a bench is not automatically ready for shipment outside the laboratory.
Basis: 29 CFR 1910.1450(e), (f)(3)(v); Appendix A chemical-management guidance
9. Apply added protection for particularly hazardous substances
By the end: Identify the approved designated area, containment, waste and decontamination controls for the substance.
The CHP must provide additional protection for work with particularly hazardous substances. These include select carcinogens, reproductive toxins and substances with a high degree of acute toxicity. The standard defines select carcinogen using specified OSHA and authoritative classification criteria; do not decide that status from a familiar trade name or a single pictogram alone.
Specific consideration must be given to designated areas, containment such as hoods or glove boxes, safe removal of contaminated waste and decontamination procedures. Include those measures where appropriate. A designated area may be an entire lab, part of a lab or a device. Marking an area does not by itself control exposure.
Review the actual substance, task and possible exposure routes with the Chemical Hygiene Officer or responsible supervisor. Establish who may work there, what approval is needed, how controls are checked and how equipment and waste will be handled. Apply the controls to everyone exposed; reproductive hazards are not relevant only to pregnant workers.
Do not rely on a small amount or short task to skip the approved precautions. Before starting, confirm containment, PPE, cleanup and emergency arrangements. If a control fails or contamination extends beyond the planned area, follow the response procedure and obtain review. This general lesson does not authorize a specific high-hazard experiment.
Basis: 29 CFR 1910.1450(b), (e)(3)(viii)
10. Manage lab-made substances and contaminated waste
By the end: Confirm hazard review for new materials and the approved waste route before generating or distributing them.
New substances and byproducts need hazard review. If a substance made only for the lab’s own use has a known composition, the employer must determine whether it is hazardous. If it is hazardous, provide the appropriate training. A new name or an unpublished result does not remove the duty to evaluate it.
If a laboratory-produced byproduct has an unknown composition, the employer must assume it is hazardous and implement the CHP provisions. If a substance is produced for another user outside the lab, the employer must comply with the Hazard Communication Standard, including SDS preparation and labeling. Outside distribution is not covered merely by an internal sample label.
Plan waste handling before work starts. Use suitable, identified containers and keep incompatible wastes separate under the approved plan. Do not combine waste just to reduce the number of bottles. Do not pour chemicals down a drain or evaporate them in a hood as an improvised disposal method. Ask the responsible waste personnel about the authorized route.
CHP controls for contaminated waste protect workers, but they do not replace applicable environmental, transport or waste-generator requirements. This is not a complete hazardous-waste compliance or shipping course. Follow the facility’s specific collection, closure, labeling, transfer and decontamination procedures, and obtain separate training where the assigned duties require it.
Basis: 29 CFR 1910.1450(h)(2), (e)(3)(viii); Appendix A waste guidance
11. Understand exposure limits and monitoring
By the end: Locate the relevant limits, monitoring decision and result-notification process for the assigned chemicals.
Applicable OSHA permissible exposure limits, or PELs, still apply in covered laboratories. Workers must be informed of those limits, or recommended exposure limits where there is no applicable OSHA standard. A recommended limit and an enforceable PEL are not interchangeable. Absence of a listed PEL does not mean a chemical is harmless.
The employer must measure exposure to a substance regulated by a standard requiring monitoring when there is reason to believe levels routinely exceed its action level, or its PEL if there is no action level. If initial monitoring shows exposure above that trigger, the employer must immediately follow the relevant standard’s exposure-monitoring provisions. Ending monitoring also follows that standard.
The employer must notify the employee of monitoring results in writing within 15 working days after receiving them, individually or by accessible posting. Understand what was sampled and the task conditions. A measurement from another procedure or location may not answer the exposure question for the current work.
Training must address methods and observations used to detect a release, including monitoring and appropriate indicators. Do not deliberately sniff for chemicals or treat absence of odor as proof of safe air. Report alarms, failed controls and unusual conditions through the lab’s process. A general course score or an SDS is not an exposure measurement.
Basis: 29 CFR 1910.1450(c)-(d), (f)(3)-(4)
12. Know the medical-access and record duties
By the end: Identify the medical-reporting and confidential record-access routes without placing diagnoses in training forms.
The employer must provide an opportunity for appropriate medical examination when an employee develops signs or symptoms associated with a chemical to which they may have been exposed in the lab. An event such as a spill, leak or explosion that creates a likelihood of hazardous exposure triggers an opportunity for medical consultation to determine whether examination is needed. Do not wait for symptoms after such an event before reporting it.
Medical surveillance is required as specified by the relevant chemical standard when monitoring routinely exceeds the action level, or PEL if no action level exists, for a substance with monitoring and surveillance requirements. Required examinations and consultations occur under a licensed physician’s supervision, without cost to the employee, without loss of pay and at a reasonable time and place.
The employer supplies chemical identity, exposure circumstances and available measurements, plus reported signs and symptoms. The required physician’s written opinion addresses the rule’s occupational findings and follow-up; it must not reveal unrelated diagnoses. Keep private medical details out of course worksheets and ordinary training records. Emergency medical help must not be delayed while paperwork is prepared.
The employer must maintain accurate exposure-measurement and required medical records and provide preservation, transfer and access under the applicable record rule. The current access rule is 1910.1020; 1910.1450 retains an older 1910.20 cross-reference. Retention periods and exceptions differ by record type. A course completion certificate does not replace these records.
Basis: 29 CFR 1910.1450(g), (j); 1910.1020
13. Respond to spills and exposures within your role
By the end: Demonstrate the alarm and reporting route, emergency-equipment location and limits of your cleanup role.
Before working, learn the lab’s alarm, reporting and protective-action procedures. Know the location and operation of emergency equipment, the safe exit route and how responders will find the room. Where eyes or the body may be exposed to injurious corrosive materials, 1910.151(c) requires suitable quick-drenching or flushing facilities in the work area for immediate use.
For a splash or exposure, promptly use the trained emergency procedure, suitable emergency equipment and medical-help route. Do not delay urgent action to finish an experiment, search for paperwork or try an improvised neutralizing treatment. The specific chemical and circumstances matter; follow the lab’s instructions and responder guidance. This course does not replace first-aid or chemical-specific emergency training.
Do not assume a spill is safe to clean because it is small. Identity, toxicity, volatility, reactivity, location and available controls all matter. Only perform cleanup within your training, authority and the actual spill procedure. For an unknown substance, failed containment or a situation beyond your role, alert others, keep clear and summon the designated response.
Protect others without entering hazardous air or an uncontrolled area. Do not improvise a rescue using borrowed respiratory equipment. Follow the evacuation and accountability arrangements and report missing people to responders. After the immediate response, obtain the required medical opportunity and review the cause, controls and readiness before restarting affected work.
Basis: 29 CFR 1910.1450(f)(4), (g); 1910.151(c); applicable emergency procedures
14. Verify readiness and review changing work
By the end: Complete actual lab instruction and employer verification, retaining any task restrictions and follow-up needs.
Use this knowledge with the actual lab’s instruction. Before assignment, locate the current CHP, procedure, SDSs and approval requirements. Explain the chemical hazards, limits, controls and emergency actions in your own words. Check that the actual equipment and materials match the procedure. Resolve missing information before exposure.
The employer or trainer should verify understanding through suitable questions, observation or safe practice. Useful tasks include finding hazard information, checking a hood’s status, selecting the approved PPE, identifying compatible storage and explaining the alarm response. Do not create a spill, exposure or unsafe experiment merely to test a learner.
Record what instruction occurred, who participated, the date, observations, corrections and remaining restrictions. These worksheets are recommended implementation tools, not a claim that 1910.1450(f) prescribes this exact form or one universal training-record retention period. Keep confidential exposure and medical records under their separate rules and access protections.
New chemicals, methods, quantities, equipment or exposure conditions may require new information, approval and instruction. Report ineffective controls and use the employer’s refresher schedule. The CHP effectiveness review is at least annual, with updates as needed, while training frequency is determined by the employer. Online completion documents this knowledge component; it does not prove that every lab task is authorized or that the facility meets every applicable requirement.
