Respirator Maintenance And Storage
• Replace damaged or dirty air filters. Filters cannot be
washed or cleaned with compressed air. Never reuse a
dirty air filter.
• Never use solvents or abrasive cleaning solutions to
clean the respirator. Keep water and other fluids out of
blower assembly.
Maintain accurate records of filter replacement and respirator
maintenance.
The respirator components should be cleaned after each use.
Use of a soft cloth dampened with a mild soap and water solution
to wipe all external surfaces of blower unit clean. Allow to dry.
Factors including product usage and workplace contamination
levels affect the life of the filters. Replace filters if air flow is
reduced because of dirty filter and according to the filter change
schedule established by your Safety Director and an Industrial
Hygienist.
Inspection of blower assembly and breathing tube after each use
is good practice. Replace breathing tube if damaged or if inside
of tube is dirty.
Storage of respirator should be in a clean, dry, cool place with the
filter and battery removed for blower assembly if respirator will
not be used for an extended period of time.
