MSA gas mask use statements
Gas mask use is restricted to entry into, or work within, atmospheres that are within canister limitations. They are not intended for oxygen-deficient atmospheres (less than 19.5% O2). Gas masks may be used for escape only from atmospheres in which the contaminant concentration does not exceed the gas mask maximum use concentration. Chin-Type Gas Masks have the following maximum use limitations: Routine use: 50 times the Permissible Exposure Level (PEL) - Do not exceed the Immediately Dangerous to Life or Health (IDLH) concentration. Escape use: contaminant concentrations up to gas mask maximum use concentrations, providing there is sufficient oxygen to support life. Gas masks are generally suitable for ventilated areas with relatively stable concentration levels. They should never be used within confined spaces, or where oxygen deficiency and/or high gas concentrations may exist.
Never use a gas mask without carefully assessing exposure conditions. Use suitable instruments to determine concentration of oxygen and air contaminants. If exposure concentrations are expected to exceed the specific canister limitations, or are unknown, only a self-contained breathing apparatus or a combination Type C supplied air respirator with auxiliary self-contained air-supply should be used. Always use strictly in accordance with canister labels, gas mask instructions and limitations. DO NOT USE FOR FIREFIGHTING.
