Lab Safety Checklist: Essential PPE and Equipment for Every Laboratory

A lab safety checklist isn’t a bureaucratic formality. It’s how labs translate regulations into daily practice and catch the gaps before something goes wrong. OSHA’s governing standard for laboratory safety is 29 CFR 1910.1450, which establishes minimum requirements for any lab working with hazardous chemicals. That standard mandates written procedures, documented training, and specific controls – and it applies whether you’re running a research facility, a clinical lab, or a university teaching space.

This guide is built for lab managers, working scientists, and students who need a practical reference for PPE requirements, engineering controls, behavioral rules, and safety symbols. The lab safety checklist structure below is designed to be used, not just read. Each section covers what’s actually required and why. A complete lab safety checklist approach means treating laboratory safety as an operational system rather than a set of posted reminders. Use this lab safety checklist as a working document, not a one-time review.

What OSHA Actually Requires: The Legal Baseline for Every Laboratory

The OSHA laboratory standard (29 CFR 1910.1450) requires any employer with employees working with hazardous chemicals to develop and implement a written Chemical Hygiene Plan. This isn’t optional, and it can’t be generic – the plan must address the specific hazards present in your lab.

The chemical hygiene plan must include standard operating procedures for handling hazardous chemicals, criteria for the use of control measures, required PPE for specific exposures, provisions for employee information and training, and procedures for emergency response. Supporting OSHA standards that feed into lab safety guidelines include 1910.132 (general PPE requirements and hazard assessment), 1910.133 (eye and face protection), 1910.138 (hand protection), and 1910.1030 (bloodborne pathogens for any lab handling biological materials).

The critical point that many labs miss: OSHA mandates a written hazard assessment before determining what PPE is required. There is no universal kit that satisfies compliance across all lab types. The right PPE for a chemistry lab working with volatile solvents differs from that required in a microbiology lab or a clinical diagnostic facility. The OSHA laboratory standard expects you to document that assessment and keep records of it.

A complete chemical hygiene plan should be reviewed annually and updated when new chemicals or procedures are introduced. It’s also the document an OSHA inspector will ask for first.

PPE Checklist: Eye, Face, and Hand Protection

Lab PPE for eye, face, and hand protection should be assessed against the specific hazards in each work area. No single lab PPE setup covers all lab types. The following items cover the standard requirements.

• Chemical splash goggles – ANSI Z87.1 rated, indirect venting, sealed against the face. Required for any work involving liquids that could splash. Prescription glasses are not a substitute; they leave gaps at the sides and top.
• Safety glasses – For low-splash risk tasks only, such as handling sealed containers or solid materials with low hazard potential.
• Face shield – Required when splash risk is elevated or when pouring larger volumes of corrosive chemicals. Used over goggles, not instead of them.
• Nitrile gloves – Standard choice for chemical resistance and broad biological protection. Check compatibility charts for the specific chemicals in use.
• Latex gloves – Avoid where latex sensitivity is a concern. Offer good biological protection but poorer chemical resistance than nitrile for many solvents.
• Cut-resistant gloves – Required when handling broken glassware, sharp instruments, or items with a cut hazard.
• Cryogenic gloves – Required for any work with liquid nitrogen or dry ice. Standard nitrile does not protect against cryogenic temperatures.

This is the core lab safety equipment for hand and face protection. Match each item in your lab safety equipment inventory to a documented hazard assessment. Match glove type to chemical compatibility data from the SDS – no single glove material is adequate for all chemical classes.

PPE Checklist: Body and Respiratory Protection

Laboratory PPE for body and respiratory protection is frequently underspecified in smaller labs. These requirements apply broadly.

• Lab coat, cotton or flame-resistant – Cotton for general chemistry and biological work. Flame-resistant (FR) fabric is required where flammability risk is present. Synthetic fabrics are not acceptable as they can melt onto skin.
• Closed-toe shoes – Required in all lab areas. No sandals, no mesh fabric. Leather provides better protection against chemical spills.
• Long trousers – Required when working with chemicals, biological materials, or open flames. No shorts in the lab.
• N95 respirator – Required when engineering controls (fume hood, LEV) are insufficient to control airborne exposures. Requires fit-testing before use and medical clearance.
• PAPR (Powered Air-Purifying Respirator) – Required for BSL-3 work and certain high-hazard chemical operations where N95 is insufficient.
• Respirator fit-testing – OSHA requires documented fit-testing before any respirator is used in a hazardous exposure situation. Annual re-testing is required. Records must be retained.

A critical note: any work with volatile solvents outside a fume hood triggers respirator requirements under 29 CFR 1910.1450. Working inside a properly functioning fume hood is the preferred lab safety control; respirators are the fallback, not the primary solution.

Engineering Controls: Safety Equipment Every Lab Must Have in Place

Engineering controls reduce exposure at the source rather than relying on behavioral compliance. This is laboratory safety equipment that must be present, functional, and regularly inspected. Laboratory safety equipment inspections must be documented to demonstrate compliance.

Ventilation

• Chemical fume hood – Required for any work generating hazardous vapors, gases, or aerosols. Sash height matters: most hoods are certified at a specific sash position that maintains adequate face velocity (typically 100 fpm). Working with the sash above the marked height defeats the purpose of the protection. Annual certification is standard.
• Biosafety cabinet (BSC) – Required for work with biological agents requiring containment. Annual certification by a certified technician is required to maintain valid protection. Class II Type A2 is the most common for BSL-1 and BSL-2 work.
• Local exhaust ventilation (LEV) – Required for specific point-source exposures, such as grinding or operations that generate particulates outside a hood.

Emergency Equipment

• Eyewash station – Must deliver tepid water for at least 15 minutes continuously. OSHA and ANSI Z358.1 require the station to be within 10 seconds of travel (approximately 55 feet) of the hazard. Must be flushed weekly and documented.
• Safety shower – Same 10-second proximity requirement. Must be tested annually with documented records.
• Fire extinguisher – Class ABC minimum for most labs. Must be within 75 feet of any point in the lab. Monthly visual inspection and annual service are required.
• First aid kit – Stocked and accessible. Contents should be matched to the hazards present (e.g., calcium gluconate gel for hydrofluoric acid labs).

Containment

• Chemical spill kit – Specific to the chemical classes in use. A universal absorbent kit won’t handle all chemical classes safely – acids, bases, solvents, and mercury each require specific materials.
• Biohazard waste containers – Rigid, leak-proof, labeled with biohazard symbols. Required for all biological waste before autoclaving or pickup.
• Sharps containers – Required for any needles, blades, broken glass, or other sharps. FDA-cleared containers only. Must not be overfilled.

Lab Safety Rules: The Behavioral Checklist That Protects Everyone

Lab safety rules are the behavioral layer that engineering controls can’t fully replace. The following lab safety rules cover the four main categories of behavioral compliance.

General Conduct

• Never work alone when handling hazardous materials. A buddy system or check-in protocol is required in many institutional policies and strongly recommended everywhere.
• No food, drink, or cosmetics in the lab. This is an OSHA requirement under HazCom and bloodborne pathogen standards, not just a courtesy policy.
• Secure loose hair, clothing, and jewelry before beginning work with equipment, open flames, or rotating machinery.
• Documented training must be completed before starting any new procedure involving hazardous materials. “I watched someone else do it” is not documented training.

Chemical Safety

• Read the SDS before first use of any chemical. Know the hazard class, PPE requirements, and emergency procedures before opening the container.
• Label every container. Unlabeled containers create hazards for everyone and are a common OSHA citation.
• Never pipette by mouth under any circumstances. This is one of the most persistent chemical lab safety violations and one of the most dangerous.
• Store incompatible chemicals separately. Flammables away from oxidizers. Acids away from bases. Refer to SDS for specific incompatibility data.

Biological Safety

• Follow the BSL protocol specific to the agents in use. BSL-2 work requires practices and containment beyond what’s adequate for BSL-1.
• Decontaminate all biological waste before disposal. Autoclaving or chemical treatment, depending on the agent, is required before waste enters the general stream.

Emergency Preparedness

• Know all exit locations from your lab and the building before you start working.
• Report all incidents, including near-misses, immediately. Near-miss reporting is how labs prevent problems from becoming injuries.
• Participate in emergency drills. Knowing the route in a calm drill means you can use it in an actual emergency.

Lab safety rules for students entering a lab for the first time should cover all four categories above, with specific emphasis on reading chemical SDSs and never working alone with hazardous materials.

Safety Symbols and Training: The Two Most Overlooked Compliance Items

Lab Safety Symbols

OSHA adopted the GHS (Globally Harmonized System) pictograms in 2012 under 29 CFR 1910.1200. Lab safety symbols appear on chemical labels, SDS documents, and containment equipment. Recognizing them is a baseline competency.

Symbol	Hazard Type	Common Location
Skull and crossbones	Acute toxicity	Chemical labels, storage areas
Flame	Flammable, pyrophoric, self-reactive	Flammables storage, solvent containers
Exclamation mark	Irritant, harmful, narcotic effects	Mid-level hazard chemicals
Biohazard	Biological agents	BSC, waste containers, sample bags
Corrosion	Skin/eye corrosion, metal corrosion	Acid/base storage, corrosive labels
Health hazard	Carcinogen, reproductive toxin, sensitizer	Long-term exposure hazard chemicals
Environment	Aquatic toxicity	Disposal guidance, drain hazards

Lab hazard symbols must be present on all chemical containers and should be posted at entry points to areas with significant hazards. Familiarity with these symbols is required under HazCom training.

Lab Safety Training

Lab safety training is mandatory and must be completed before work begins. OSHA requires that employees receive training before working with hazardous chemicals, not during onboarding at a general level. The chemical hygiene plan dictates the specific training content.

Mandatory training modules under 29 CFR 1910.1450 include:

• Chemical Hygiene Plan – content, location, and employee rights
• HazCom (29 CFR 1910.1200) – SDS reading, label interpretation, lab safety symbols
• PPE selection and use (29 CFR 1910.132)
• Emergency response procedures specific to the lab

Training records must be documented and retained. OSHA does not specify a retention period for training records under 1910.1450, but most compliance programs retain records for the duration of employment plus three years. Refresh training is required when new hazards are introduced, when procedures change, or when an incident suggests the original training was inadequate.

Lab safety training that isn’t documented effectively didn’t happen from a compliance standpoint.
