Laboratories in which employees handle biosafety level 2 (including laboratories handling human blood, OPIM and human cell lines) or biosafety level 3 agents, must be posted with the Universal Biohazard Sign and the Principal Investigator’s name and contact information. The lab entrance signage system can be used or a separate BSL2 door placard may be generated.
