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.
