Biosafety levels 2, 3, and 4 require the placement of a biohazard sign on the door of the laboratory. This signage is essential to inform personnel and visitors about the potential risks associated with the pathogens handled within these facilities. The sign typically indicates the specific biosafety level and outlines necessary precautions. Level 1 labs do not require such signage as they deal with minimal risk agents.

There are four biosafety levels (BSL) that range from BSL-1 (basic level) to BSL-4 (high level). BSL-1 involves basic safety practices, while BSL-2 requires additional precautions for moderate-risk agents. BSL-3 includes strict containment measures for pathogens that can cause serious diseases, and BSL-4 is for handling dangerous pathogens with no vaccines or treatments, requiring maximum containment.
