Tight Fitting requires Fit Testing

Tight Fitting requires Fit Testing

• A. Respiratory Protection Program
• B. PPE (Personal Protective Equipment)
• C. Fit Testing
• D. IDLH

Answer: (C)

A tight-fitting respirator must be verified to seal properly through fit testing. The purpose of this test is to confirm that the facepiece actually forms a good seal to the wearer’s face, so contaminants can’t bypass the filter through gaps around the edges. Without a proper seal, the protection expected from the respirator won’t be realized, even if the filter itself is effective. Fit testing can be done qualitatively, where the wearer must detect a test agent by taste or smell or sensation, or quantitatively, where a instrument measures the amount of leakage and provides a numerical fit factor. This testing is a central part of a respiratory protection program and is performed before initial use and at specified intervals, and whenever facial characteristics change enough to affect fit. PPE is a broad category that includes respirators, but merely having PPE does not guarantee protection. IDLH describes a highly hazardous environment requiring a respirator, but it does not by itself ensure the respirator fits properly. The essential point is that a tight-fitting respirator must undergo fit testing to confirm an adequate seal.
