A lab safety checklist can serve as a map to help science teachers navigate through safer waters.
The list not only makes labs safer for students but also fulfills part of the teacher’s legal responsibility for inspecting, securing, and maintaining a safer learning space. For school districts regulated under the Occupational Safety and Health Administration (OSHA), the list needs to reflect fundamental elements of the Laboratory Standard and Hazard Communication Standard. Non-OSHA regulated school districts need to incorporate state and local safety regulations for academic labs into their lists. OSHA’s webpage contains safety and health standards and regulations specific to each state.
The following checklist addresses most—but not all—situations in K–12 science laboratories, but it can be tailored to meet the needs of individual laboratories.
Environmental health and safety
• Is there an active environmental health and safety program (e.g., chemical hygiene plan) addressing management of biological, chemical, and physical hazards specific to your work-site?
• Is there a person designated for the implementation and enforcement of the safety program (e.g., chemical hygiene officer)?
• Is there a department or school safety committee composed of employees and employers that meet regularly and write reports on their activities?
• Is there a process for handling employee complaints regarding environmental health and safety issues? To give an example, employees can submit a reporting form to their supervisors to address safety issues. Employees can also file a confidential complaint with OSHA to have their workplace inspected.
Personal protective equipment
• Is there a process to determine whether activities contain hazards requiring the use of personal protective equipment, or PPE (e.g., head, eye, face, hand, or foot protection)? This process involves three steps: hazards analysis, risks assessment, and safety action. Once risks are assessed after the hazards analysis, the safety action would determine which types of PPE are required for a safer activity.
• If hazards are found, are employers, employees, and students using the proper PPE?
• Are indirectly vented chemical splash goggles worn where there is a danger of flying particles or corrosive materials?
• Are safety glasses worn where there are solids hazards such as projectiles and meter sticks?
• Are employees and students who have glasses or contacts required to wear approved safety glasses, protective goggles, or use other precautionary procedures such as eliminating the use of contacts.
• Are there gloves, aprons, shields, or other protection for employees and students to protect themselves against hazards such as corrosive liquids, sharp objects, and chemicals?
• Is all protective equipment well maintained and ready for use?
• Are there eye wash facilities and a drench shower within the work areas that contain hazardous chemicals or biologicals?
• Are food and beverages consumed in areas where there is no exposure to hazards?
Flammable and combustible materials
• Are approved containers and tanks used for storing and handling flammable and combustible liquids? Containers or tanks for such storage or handling must meet OSHA’s Flammable Liquid standard and have labeling noting that it meets the standard.
• Do storage rooms for flammable and combustible liquids have explosion-proof lights and mechanical or gravity ventilation?
• Are fire extinguishers for combustible; liquid, gas, or grease; and electrical equipment fires placed in the appropriate areas?
• For electrical equipment fires:
• Are all work-sites clean, sanitary, and orderly?
• Are work surfaces slip-resistant?
• Are all spilled hazardous materials or liquids, including blood and other potentially infectious materials, cleaned up immediately according to proper procedures?
• Is all regulated waste, as defined in the OSHA bloodborne pathogens standard (1910.1030), discarded per federal, state, and local regulations?
• Are aisles and passageways kept clear?
• Is there a current inventory of hazardous substances in your workplace?
• Is there a written hazard communication program dealing with safety data sheets (SDSs), labeling, storage, disposal, and employee training?
• Is each container (i.e., vats, bottles, storage tanks) for a hazardous substance labeled with product identity and hazard warning information?
• Is an SDS readily available for each hazardous substance at the work-site?
• Is there an annual employee training program for hazardous substances?
• Does this program:
• Are employees trained to:
Meeting OSHA’s Laboratory and Hazard Communication standards
• Are there safety engineering and administrative controls, including standard operating procedures?
• Are there criteria (e.g., proper housekeeping) for implementing and inspecting specific controls?
• Is there annual testing and certification of fume hoods?
• Is there access to information and training requirements?
• Are there laboratory operations that require approval of the employer or chemical hygiene officer? For example, the use of a new hazardous chemical might require the pre-approval of the chemical hygiene officer.
• Are there provisions for medical consultation and exams?
• Is there a designated chemical hygiene plan?
• Is there a chemical hygiene officer?
In the end
A good place to start a safety inspection is by answering the questions on the checklist, which provides a viable safety assessment and improves safety in the learning environment.
