DO NOT use for urethane paints or other paints containing 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 damage to the respiratory system.
If unable to develop an appropriate change-out schedule, use an air-supplied
respirator or SCBA.
When using filters in an application that produces sparks, ensure that you are
protected by a shield. Contact with sparks can damage filters and reduce
protection.
RESPIRATOR USE LIMITATIONS
The wearer must comply with the following respirator use limitations:
1. MAXIMUM USE CONCENTRATION — Do not exceed any of the following:
a. 10 times the exposure limit for the contaminants present.
b. Immediately dangerous to life or health (IDLH) concentration for any contaminant present.
2. The limitations outlined in the applicable NIOSH approval.
3. For respirators with class N or R filters: Replace filters after no more than 8 (eight) hours of
use (continuous or intermittent) or sooner if excessive breathing resistance occurs while
inhaling. [Service time can be extended by performing an evaluation in the specific workplace
setting that demonstrates (a) that the extended use will not degrade the filter below the
efficiency level for which it is approved, or (b) that the total mass loading of the
filter is less than 200 mg.]
4. For respirators with class P filters: Replace filters when excessive breathing resistance
occurs while inhaling.
5. For respirators with chemical cartridges:
a. Users must follow an appropriate cartridge change-out schedule developed by a qualified
professional. The change-out schedule must take into account all factors that may
influence respiratory protection including specific work practices and other conditions
unique to the work environment. Cartridges equipped with an end-of-service-life indicator
for a specific contaminant present must be replaced when the indicator changes to the
specified color or sooner if using the respirator against a mixture and the cartridge change-
out schedule specifies an earlier replacement. See MSA's Cartridge Life Expectancy
Calculator at www.webapps.msanet.com/cartlife/
b. If using the respirator against substances having poor warning properties, over exposure
can occur without user awareness. Take appropriate precautions to prevent overexposure,
which may include an earlier cartridge change-out, or using an air-supplied respirator or
SCBA. For further information refer to MSA's Response
c. Replace cartridges every shift, or sooner if indicated by change-out schedule or end-of-
service-life indicator. Use beyond one shift could result in shorter than expected service
time and over exposure due to contaminant desorption and migration through the cartridge
when not in use.
d. If using the respirator for escape, replace cartridges after each escape. Once the user
breathes through the respirator in a contaminated atmosphere, the cartridges may not
