Laboratory Safety A general definition of laboratory is a "room or building equipped for scientific experimentation or research." [American Heritage Dictionary] The OSHA standard regarding occupational exposure to hazardous chemicals in laboratories distinguishes laboratories that fall within its scope by defining laboratory to mean a facility where the "laboratory use of hazardous chemicals" occurs. A workplace where relatively small quantities of hazardous chemicals are used on a non-production basis. In the bloodborne pathogens standard, laboratory refers to a research laboratory which is defined as "a laboratory producing or using research-laboratory-scale amounts of HIV or HBV. Research laboratories may produce high concentrations of HIV or HBV but not in the volume found in production facilities." Laboratory Safety Hazard Overview Solutions Regulations Learn More What are the hazards associated with working in laboratories? The physical hazards associated with working in laboratories can include: flammable liquids, gases and solids; compressed gases; water-reactive chemicals; and pyrophoric chemicals. The health hazards associated with the use of chemicals in laboratories arise from chemicals that exhibit one or more of the following properties: acute and chronic toxicity (single organ and multiple organ); mutagenic; carcinogenic; irritation (ranging from slightly irritating to strongly irritating); and respiratory sensitization. Additional health hazards in laboratories pertain to work with biological hazard such as, but not limited to, bloodborne pathogens (e.g., HIV, HBV, HCV, Ebola virus), Mycobacterium tuberculosis, methicillin-resistant Staphylococcus aureus (MRSA), and other emerging disease-causing microorganisms. What can I do to protect myself? "Think bad in the lab!" Whether dealing with chemical or biological hazards, plan your work in advance to include how to respond to deviations in procedures (e.g., chemical fume hood failure, glove tear, unexpected chemical reaction, etc.) so that you are not injured or made ill. Be sure to follow established laboratory protocols and procedures. Ensure that all protective laboratory equipment (e.g., chemical fume hoods, biological safety cabinets (BSCs) are properly functioning and the appropriate personal protective clothing and equipment (e.g., lab coats, gloves, face shield, respirators) is worn when working with hazardous chemicals and biological hazards. Consult safety data sheets (SDS) in advance of work for chemical hazard identification, proper precautions and incompatibilities, and appropriate personal protective equipment (PPE). What resources are available to assist employers? Safety and Health Programs Example programs for chemical hygiene, hazard communication, bloodborne pathogens, PPE hazard assessment, hazardous chemical program, and respiratory protection are available for download and should be customized to fit workplace hazards and conditions. Training and Outreach Services Presentations on a variety of topics associated with laboratory work are available to assist employers in training their employees. These include: bloodborne pathogens; PPE; hazard communication; and respiratory protection. In addition, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. The following pre-recorded webinars are also available to assist with training; respiratory protection, bloodborne pathogens and hazard communication. Lastly, the NCDOL Library offers free safety and health videos (including streaming vdeo services) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC). A-Z Safety and Health Topics A-Z topic pages on bloodborne pathogens, compressed gases, flammable liquids, formaldehyde, hazard communication, personal protective equipment, eyewash stations and emergency showers and respiratory protection can provide more resource information. Consultation Services The consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards. Which standards apply?
