BSL-2 laboratories must be identified with proper signage. At UNL, the signage varies in appearance depending on whether the biological agents are human, animal, or plant pathogens. Regardless, the sign will indicate the containment level of the laboratory; it will detail procedures for entry and exit from the laboratory; and provide contact information for persons knowledgeable about the laboratory.
When human biohazards are present in a laboratory, the above-listed components are incorporated into standard EHS door placards (see image). The biohazard symbol is displayed in black ink on an orange background along with the containment level for the room, the words “Human Biohazards Present” and standard exit procedures advising personnel to remove PPE and wash hands prior to exiting the lab.
For security reasons, we also do not indicate the actual agent in use except for HIV and Hepatitis B research labs as it is required by the OSHA Bloodborne Pathogens Standard.
Cite this item if you visit a lab designated as BSL-2 and it does not have an appropriate sign at the lab entrance. When this item is cited, it should be referred to the BSO for creation of the appropriate biohazard signage. The signage will then be sent through Campus Mail to the PI for posting or delivered in person.
