3.6 Respirators

Respirators are an effective method of protection against designated hazards when properly selected and worn.  Respiratory Protection includes all NIOSH approved respirators: Filtering Facepieces (Disposable respirators, N95’s, Dust Masks), Tight Fitting Half and Full Face Respirators, and Powered Air Purifying Respirators. Engineering controls, such as dilution ventilation, fume hoods, and other devices, which capture and remove dust, vapors, fumes, and gases from the breathing zone of the user are preferred over the use of respirators in most laboratory environments.
