INTRODUCTION
INSTRUCTIONS FOR USE AND CARE BY PROPERLY
TRAINED AND QUALIFIED PERSONNEL
1. This device does NOT supply oxygen. Use only in
adequately ventilated areas containing at least 19.5
percent oxygen.
2. This respirator must be used in conjunction with
proper chemical or particulate cartridges for pro-
tection against specific contaminants.
3. Do not use when concentrations of contaminants
are unknown or immediately dangerous to life or
health (IDLH). (See the respirator NIOSH approval
plate P/N 816882 to determine if this device can be
used for escape from those concentrations.)
4. Do not use when appropriate exposure limit
(OSHA, PEL, NIOSH REL, ACGIH TLV, etc) is not
known or when it is below the odor threshold or
any other established warning level for the conta-
minant.
5. Leave area immediately if:
a. Breathing becomes difficult.
b. Dizziness or other distress occurs.
c. You taste or smell the contaminant.
d. You experience eye, nose or throat irritation.
6. Use strictly in accordance with instructions, labels,
and limitations pertaining to this device.
7. This device may not seal properly if beards, side-
burns, or other similar physical characteristics pre-
vent direct contact between the skin and the seal-
ing surface of the facepiece (see NFPA-1500 and
ANSI 788.2). Do not use this device if such condi-
tions exist.
8. The face-to-facepiece seal must be tested before
each use.
9. Never remove the facepiece except in a safe, non-
hazardous, non-toxic atmosphere.
10. Never alter or modify this device.
11. This respirator is for use by training, qualified per-
sonnel only.
Failure to follow the above warnings can result in seri-
ous personal injury or death.
DO NOT use for urethane paints or other paints con-
taining diisocyanates unless an appropriate cartridge
change-out schedule is developed. Due to their poor
warning properties, over exposure can occur without
user awareness and result in severe permanent dam-
age to the respiratory system. If unable to develop an
appropriate change-out schedule, use an air-supplied
respirator or SCBA. Failure to follow this warning can
result in serious personal injury or death.
RESPIRATOR USE LIMITATIONS
The respirator must not be worn in atmospheres which
exceed any of the following limitations:
1. Maximum use concentrations
a. Full facepiece and hood PAPRs: 1000 times the
exposure limit for the contaminants present.
b. Half-facepiece PAPRs: 50 times the exposure limit
for the contaminants present.
c. 1000 parts per million organic vapors (for organic
vapor respirators).
2. The limitations outlined in the applicable NIOSH
approval.
3. Any applicable limitation contained in a standard
established by a regulatory agency (such as OSHA)
with jurisdiction over the wearer.
4. Do not use for respiratory protection against the fol-
lowing contaminants regardless of concentration or
time of exposure. This far-from-complete list is offered
only as a guide to proper evaluation of the many cont-
aminants found in industry. Contact MSA for further
information on other specific material.
5. This respirator can be used for protection against a
mixture of contaminants that are present simultane-
ously or alternately against one contaminant then
another (using the same cartridges or filters) if the
mixture meets the following conditions:
a. The cartridge/canister/filter must be approved for all
contaminants present.
b. Particulates (dusts, mists, fumes, asbestos,
radionuclides) can be mixed with any other particu-
late or any gas or vapor for which the car-
tridge/canister is approved.
c. Contaminants present simultaneously must be
below IDLH levels for the specific contaminants. If
any one contaminant in the mixture exceeds the
IDLH concentration then the entire mixture must be
treated as IDLH and the respirator cannot be used
(except for escape from particulates with appropri-
ate filter).
