SPECIAL USERS INSTRUCTIONS
This respirator can be used for protection against a mixture of contaminants that are present
simultaneously or used alternately against one contaminant than another (using the same cartridge of
filters) if the mixture meets the following conditions:
i. The cartridge/ filter must be approved for all contaminants present.
j. The particulates can be used mixed with any other particulate or any gas or vapor to which the
cartridge is approved.
k. Contaminants present simultaneously must be below IDLH levels for the specific
contaminants. If any of the contaminant in the mixture exceeds the IDHL concentration, then
the entire mixture must be treated as IDLH, and the respirator cannot be used (except for
escape from particulates with appropriate filter.)
®
l. Mersorb and Mersorb P3 cartridges can be used against a mixture of chlorine and Mercury
that are both present simultaneously, but cannot be used if alternating between mercury
contaminated atmosphere and chlorine contaminated atmospheres.
Mersorb and Mersorb-P3 filters utilize an end of service life indicator (ESLI) for use against metallic
mercury vapor. The passive ESLI must be visible whenever the respirator is in use, without
manipulating the respirator or the indicator. If you cannot see the indicator readily, do not use the
respirator. The band around the side of each Mersorb and Mersorb P3 consists of a 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 the cartridge.
