Respirator Fit Testing


Respirator fit testing is required for mandatory use of all tight-fitting facepieces and recommended for voluntary use. OSHA 1910.134(f) states: “The employer shall ensure that an employee using a tight-fitting facepiece respirator is fit tested prior to initial use of the respirator, whenever a different respirator facepiece (size, style, model or make) is used, and at least annually thereafter.” Employees issued powered air purifying respirators and supplied air respirators with loose-fitting facepieces, hoods or helmets are not subject to respirator fit testing.
