Upon inhalation, contaminated air enters the gas mask canister, where it is filtered before reaching the wearer, who breathes in only clean, fresh air.
The MSA Chin-Type gas mask has been certified by the National Institute for Occupational Safety and Health (NIOSH). The specific numbers are shown under ordering information for each mask type.

Provides respiratory protection against particulate matter, vapors and gases by means of a lightweight, replaceable canister. The small, oval-shaped aluminum canister and facepiece are designed to permit downward head movement. This comfortable, lightweight model is an alternative to the heavier models and is designed for respiratory protection against a specific gas or group of gases as indicated by canister identification. The gas mask assembly has the following Maximum Use Conditions: Entry - 100% the Permissible Exposure Level; do not exceed the Immediately Dangerous to Life and Health (IDLH) concentration. Escape - contaminant concentrations up to the maximum use concentration of the gas mask (generally 5,000 ppm (0.5%) by volume; see canister selection chart for details), providing there is adequate oxygen (19.5% by volume) to support life. At these upper use conditions, the service time may be as short as 12 minutes. Also available as a belt-mounted version which allows the wearer to attach the canister to a belt clip and uses a corrugated breathing tube to connect the canister to the facepiece.
WARNING: Do not use for fire fighting.
