*BSL-2 with BSL-3 practices laboratories with approved decontamination procedures to lower containment to BSL-2 must follow the posting requirements in their laboratory-specific standard operating procedures (SOPs).

BiohazardsignPrintable

For BSL-2 laboratories, when work is complete, agents are secured, and surfaces are decontaminated, the Biohazard Warning Sign may be removed or turned over. Affix the Biohazard Warning Sign to entry doors in such a way that it can be easily removed or turned around (e.g., place sign in plastic cover). If the Biohazard Warning Sign is affixed to a BSL-2 laboratory door, support staff such as UW Facilities or Custodial Services will not enter.

When finished, print in color on 8 1/2" x 11" white paper. This biohazard symbol on the sign is required to have the orange background with the symbol and lettering in a contrasting color.

The Biohazard Warning Sign restricts laboratory access during work with biohazards, communicates the agents in use, and specifies entry or exit requirements. It is the responsibility of the Principal Investigator or supervisor to properly identify and restrict access to the laboratory and to notify emergency and support personnel of any hazards in the laboratory.

Use the "Special Procedures, PPE or Precautions for Entry/Exit" section to list specific entry/exit requirements, PPE required for work and any occupational health requirements.

The Biohazard Warning sign is posted in addition to the biohazard symbol on the permanently affixed caution sign next to laboratory entry doors. The Biohazard Warning Sign must be permanently affixed to entry doors of the following laboratories/rooms:

Delineators are retro-reflective devices typically mounted above the roadway surface and at continuous intervals along the side of the roadway to indicate alignment of the roadway. Variants to the MUTCD defined delineators are commonly used in conventional plazas to channelize vehicles into a toll lane and prevent crossing into or out of a channelized lane or accessway. The more commonly used delineators installed to separate vehicles are tubular flexible stanchions that are anchored to the pavement using adhesives and or hardware. Pop-up delineators are also available and should be considered for use at plazas with reversible lanes. Delineators used to define plaza alignment are commonly rigid and are anchored below the ground surface.

Enter contact information for all Principal Investigators (PI) using the laboratory. Enter an emergency contact including an after-hours phone number.

BSL-2 is the default biosafety level. Use the dropdown arrow to select the appropriate biosafety level. For BSL-1, a Biohazard Warning Sign is not required unless specified by EH&S/IBC; the biohazard symbol on the permanently affixed UW Laboratory Entry Caution Sign next to laboratory entry doors is sufficient.

For BSL-1/ABSL-1 laboratories, no Biohazard Warning sign is required. The biohazard symbol on the permanently affixed Caution Sign for hazards is sufficient.
