Centrifuges (All centrifuge buckets must be covered with bucket covers while centrifuging and may only be opened in the biosafety cabinet.)
C. Spills in a centrifuge
If a user suspects that there has been a spillage inside a centrifuge within the BSL-3 facility, the centrifuge should not be opened! The centrifuge should be marked visibly with some sort of sign or some tape placed over the still closed handle that warns other users: "suspected contamination: DO NOT OPEN!" The incident must be reported to the BSL-3 Laboratory Manager or the Safety Officer immediately. They will do a risk assessment of the situation and decide on a course of action for decontamination.
