Respirator Limitations
- Site respirators
filter air, they do not supply air, so they are useless in an oxygen
deficient atmosphere.
- Filters can
become clogged, being harder to breath through. Change regularly.
- Acid Gas/Organic
Vapor Cartridges can become saturated and useless. Cartridges should
be changed according the schedule in the Contractors Respiratory
Protection Program.
Respirators
- If the respirators
doesnt seem to fit, ask for a new brand or size and get refitted.
- If you feel
bad while wearing a respirator, ask about a new medical evaluation.
- If you have
any questions about respirators, ask for your employers program
administrator or written program.
