In all circumstances, research and animal care personnel must wear a disposable jumpsuit or lab coat, shoe coverings, hair covering, gloves, and a respiratory comfort mask when entering DLAM animal housing facilities or procedure rooms (refer to Chapter 14: Safe Handling of Laboratory Animals). As discussed in Chapter 5, comfort masks are not respirators. The comfort masks provided in several DLAM facilities do not protect you from airborne exposures; instead, they protect the laboratory animals from your exhalations. Personnel with exposure to airborne particulates contaminated with reproductive toxins without the use of primary containment must wear an appropriate respirator of N95 or higher protection, rather than a comfort mask. Refer to the Respiratory Protection section of Chapter 5: Protective Clothing and Equipment, for a description of respirator types.

EHS must approve the selection and use of respirators, and wearers are to participate in the UNC Respiratory Protection Program.

Do not wear the comfort mask or respirator outside of the animal room or procedure room. For tight-fitting cartridge respirators, dispose of used filters and decontaminate the respirator housing daily.
