RESPIRATOR USE
After Exposure to a CBA Contaminated Area
1. A decontamination procedure for the user and the
protective equipment should be developed and
implemented.
2. Once the user leaves the contaminated area, they
should enter the decontamination area and follow
the set decon procedure. Failure to follow an
acceptable decon procedure could lead to serious
injury or death.
3. Once the user and the protective equipment have
been decontaminated, proper disposal of affected
equipment is to be performed. Disposal is to be
performed as required by federal, state and/or local
laws that apply to CBA contaminated materials.
Failure to follow accepted safety and protection pro-
cedures when exposed to hazardous atmospheres can
result in serious personal injury or death.
DECONTAMINATION
The PAPR may be used in some applications which may
require decontamination of personal and respiratory
equipment before the respirator may be removed. One
such application is asbestos exposure decontamination.
Turn the motor-blower off before entering a decontamina-
tion shower. If the PAPR is equipped with a tight-fitting
facepiece it still provides respiratory protection with the
motor-blower off because all air is still drawn through the
filters, chemical cartridges, or CS/CN canisters. However,
breathing resistance will be greater than when the motor-
blower is supplying air to the facepiece.
If you are using a PAPR hood model, leave the motor-
blower on. Do not breathe through the respirator for
long periods of time with the motor-blower shut off.
CO2 can build up in the hood causing serious person-
al injury or death.
SERVICE LIFE INDICATOR
The Mersorb-HE combination cartridge utilizes an End-of-
Service-Life Indicator for use against metallic mercury
vapor. The small area on the end of each cartridge con-
sists of chemically treated paper. In use, as the paper is
exposed to metallic mercury vapor, it changes from
orange to brown. When the indicator color changes to
brown, the cartridge is beginning to lose its effectiveness
against metallic mercury vapor and must be replaced.
Thus, the wearer has a constant, positive check on the
condition of his cartridges.
CARTRIDGE CHANGE-OUT SCHEDULE
If a cartridge or canister with an appropriate ESLI is not
available, a change-out schedule based on objective
information or data that will ensure that the cartridge(s) or
canister is changed before the end of its service life, must
be developed and implemented.
Service time is the measured or estimated period of time
before breakthrough of an airborne contaminant (gas or
vapor) for a specific chemical cartridge under specified
conditions of the test.
The service time data presented in this investigation
applies only to MSA respirators. It should be used as a
guide only for determining an appropriate respirator car-
tridge change-out schedule as required for compliance
with OSHA’s Respirator Protection Standard (29 CFR
1910.134).
