5.1.2 Signage / Labeling

All areas and laboratories that contain biohazardous agents must be posted with a biohazard sign (Figure 1).

Laboratory supervisors and PIs must ensure that labels on incoming containers of biohazardous agents are not removed or defaced.  Laboratory containers, including bottles, flasks, sample vials, etc., must be marked, labeled or coded in all cases.  The label should be dated and should identify the owner of the agent.
