![]() BSL-2 laboratories must also have access to equipment that can decontaminate laboratory waste, including an incinerator, an autoclave, and/or another method of decontamination, depending on the biological risk assessment. Design requirements for BSL-2 laboratories include hand washing sinks, eye washing stations, and doors that close and lock automatically. The lab should have doors to separate the working space with the rest of the facility.īSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a moderate danger if accidentally inhaled, swallowed, or exposed to the skin.A sink must be available for hand washing.PPE (lab coats, gloves, eye protection) are worn.Work can be performed on an open lab bench or table. ![]() Standard microbiological practices are followed.Specific considerations for a BSL-1 laboratory include the following: Standard engineering controls in BSL-1 laboratories include easily cleaned surfaces that are able to withstand the basic chemicals used in the laboratory. Workers follow basic safety procedures, called standard microbial practices, and require no special equipment or design features. ![]() Laboratory Containment for Human Pathogens:īiosafety Level 1 – Biosafety Level 4 facilitiesīSL-1 labs are used to study infectious agents or toxins not known to consistently cause disease in healthy adult humans or animals. The assignment of a biosafety level to a particular work process is made through a protocol driven risk assessment.įor more information on other aspects of the biosafety levels, please see the rest of the biosafety section for a general overview. Each biosafety level has its own specific containment controls. Each biosafety level builds on the controls of the next lower level.
