Definition - What does Tight-Fitting Facepiece mean?
A tight-fitting facepiece is the part of a respirator that fits against the face of the wearer. A respirator with a tight-fitting facepiece is a type of personal protective equipment (PPE) that protects an individual against exposure to airborne hazardous agents. To be effective, this facepiece must form a complete seal against the face of the wearer, preventing ambient air from entering the the space within the facepiece. Any leakage around the edges of the facepiece will permit air from the environment to enter the mask and puts the wearer at risk for exposure to airborne hazards.
Tight-fitting facepieces are most often made of durable, flexible materials such as silicone, neoprene or natural rubber. Usually, a harness or strap is used to hold the facepiece in place.

When a respirator with a tight-fitting facepiece is worn, the mask or facepiece must fit securely against the worker's face.

A separate mask seal test should be conducted each time the worker puts on the mask and before entering an area that contains airborne hazards.
