Respiratory Protection RESPIRATORY > FITTING INSTRUCTIONS

For optimum protection against airborne hazards, your respirator must be fitted correctly. Follow the instructions to achieve the best result.

FIT-TESTING There are two types of facial fit-tests.

FITTING REUSABLE RESPIRATORS 2 1

Qualitative fit-testing is a simple pass/fail test based upon the user’s subjective assessment of the leakage, via the face seal region, of a test agent. Quantitative fit-testing uses equipment (usually a Portacount machine) to measure the efficiency of a respirator in preventing materials in the atmosphere from entering a user’s breathing zone. The Bitrex Fit Test Kit is the most commonly used and is suitable for testing both disposable and reusable respirators fitted with a particulate filter.

1 Loosen the elastic band without completely pulling the band out of the slots in the crown suspension. 2 Pull gently on the lower neck strap, creating a large loop. Put lower neck strap loop over the head. 3 Place the respirator to the face, covering the mouth and nose. (The narrow part of the facepiece should be over the nose.) Pull the crown suspension over the head and adjust its placement until it is comfortable. 4 Using both hands, grasp the free ends of the elastic band and gently pull the elastic straps away from your face until the respirator is snug and seated comfortably. Be sure the neck strap is flat and smooth against the back of the neck. To tighten the neck strap, make intermediate adjustments at the straps as they exit the top slots on the yoke. Gently pull the free ends to make final adjustments and secure a comfortable fit of the respirator to your face.
