GENERAL DESCRIPTION

D. MIXTURES OF CONTAMINANTS – This gas mask can

be used for protection against a mixture of contami-
nants that are present simultaneously or alternately
against one contaminant then another (using the same
canister) if the mixture meets the following conditions:

1. The canister must be approved for all contaminants

present.

2. NIOSH permits mixing of the following contaminants:

organic vapors, chlorine, chloride dioxide, hydrogen
sulfide, acid gases, ammonia, and carbon monoxide.

3. Particulates can be mixed with any other particulate or

any gas or vapor for which the canister is approved.

4. Contaminants present simultaneously must be below

IDLH levels for the specific contaminants. If any one
contaminant in the mixture exceeds the IDLH concen-
tration, then the entire mixture must be treated as
IDLH and the respirator cannot be used (except for
escape when using respirator in a gas mask configu-
ration).

5. Mersorb-P100 cartridges can be used against a mix-

ture of chlorine and mercury that are both present
simultaneously, but cannot be used if alternating
between mercury-contaminated atmospheres and
chlorine-contaminated atmospheres.

E. TIME USE LIMITATION
1. Canisters and cartridges with an N95 or R95filter shall

be limited to 8 hours of use (continuous or intermit-
tent) against particulates. (Service time can be extend-
ed by performing an evaluation in the specific work-
place setting that demonstrates (a) that the extended
use will not degrade the filter efficiency below 95%, or
(b) that the total mass loading of the filter is less than
200mg for a single canister application or less than
100 mg each for a dual cartridge application).

2. GMHF-C-P100 and Hydrogen Fluoride/P100: Canister

must be replaced after each use against hydrogen flu-
oride (not to exceed 12 hours) to ensure the integrity
of the P100 filter.

MULTI-USE LIMITATIONS

(OptiFilter XL only)

1. Approved as a high efficiency particulate air filter on

approved Powered Air Purifying Respirators. Also,
approved as a P100 filter, but ONLY when used with
an approved negative pressure respirator. Do not
exceed maximum use concentrations established by
regulatory standards.

EXPOSURE LIMITS FOR MIXTURES

The American Conference of Governmental Industrial
Hygienists (ACGIH) publishes the following information to
determine the TLV of a mixture.

First, determine the total concentration of the chemical
mixture (CMixture) from the individual contaminant con-

centrations (C1, C2, C3...) using the following formula:

CMixture = C1+C2+C3+...

The TLV of the mixture is found by using the following for-
mula where T1, T2, T3, ... are the individual contaminant

TLVs and C1, C2, C3... are the individual contaminant

concentrations:

Only use these equations if the contaminants present are
actually mixed. Some substances do not mix and may be
present separately, for example, in pockets or at different
levels. In that case, the lowest TLV of the substances pre-
sent must be used to determine the appropriate respirator
category for protection against all contaminants present.
