NFPA-1500, as well as ANSI Standards Z88.2 and Z88.5,
describe three levels of inspection procedures which are to be
performed. Refer to these documents, or to an inspection
program prepared by a health professional in establishing an
inspection program.
• If the air mask exhibits any of the conditions listed in the
Component Inspection section or if the air mask does
not function properly as described in the Functional
Tests section, the air mask must be removed from
service.
• DO NOT inspect the air mask before cleaning if there is
danger of contacting hazardous contaminants. Clean
and disinfect first, then inspect.
• Never substitute, modify, add, or omit parts. Use only
exact replacement parts in the configuration as specified
by the manufacturer.
Misuse can result in serious personal injury or death.
