| Changing site conditions
indicate a change in employee exposure |
Review and adjust the
level of protection as appropriate
Note:
You may decrease the level of protection
when information indicates this won't increase employee
exposure to safety or health hazards |
There is a substantial
possibility that skin absorption or contact with a hazardous
substance may:
- Impair an employee’s ability
to escape
- Cause immediate serious illness or
injury
- Is an IDLH or immediate death hazard
|
Use totally encapsulating
chemical protective (TECP) suits and make sure they will
protect employees from the hazards
- Use, decontaminate, inspect, and
remove TECP suits from service according to the manufacturer's
recommendations.
- Perform any TECP integrity tests
recommended by the manufacturer and make sure all TECP
suits are capable of:
- - Maintaining positive air pressure
- - Preventing inward test gas leakage
of more than 0.5%
Note:
Follow the manufacturer's recommended
procedures for testing a TECP suit's ability to maintain
positive air pressure and prevent inward gas leakage. Other
established test protocols for these suits, for example,
NFPA 1991 and ASTM F1052-97, may also be used |
There
is a substantial possibility that employee exposure to hazardous
substances will either:
- Immediately cause death, serious
illness, or serious injury
or
- Impair an employee's ability to escape
|
Use a positive-pressure
SCBA or an airline respirator with an escape SCBA
- Protect air supply from contamination
and the entire respirator system from physical damage.
