Respirator Use Limitations - Advantage 200LS Instructions

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 inter-
mittent) or sooner if excessive breathing
resistance occurs while inhaling. [Service
time can be extended by performing an
evaluation in the specific workplace set-
ting 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 load-
ing 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 car-
tridge change-out schedule developed
by a qualified professional. The
change-out schedule must take into
account all factors that may influence
respiratory protection including specif-
ic 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 speci-
fies an earlier replacement.
b. If using the respirator against sub-
stances having poor warning proper-
ties, over exposure can occur without
user awareness. Take appropriate pre-
cautions to prevent overexposure,
which may include an earlier cartridge

change-out, or using an air-supplied
respirator or SCBA. For further infor-
mation refer to MSA's Response
Respirator Selector.
c. Replace cartridges every shift, or
sooner if indicated by change-out
schedule or end-of-service-life indica-
tor. 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 atmos-
phere, the cartridges may not provide
adequate protection for additional
escapes. Additionally, once the car-
tridges are initially placed into service
or carried by the user in anticipation of
escape, they must be replaced based
on an appropriate cartridge change-
out schedule. Extended exposure of
the cartridges to nuisance levels
(below the PEL) of the contaminant
may prevent the cartridges from pro-
viding adequate escape protection.
tridges (chemical cartridges with filters):
The limitations specified above for
chemical cartridges as well as the
applicable filter class apply for combina-
tion cartridges.
as specified in the OSHA Respiratory
Protection Regulation 29 CFR Part
1910.134 (or other requirements estab-
lished by the Regulatory Agency with
jurisdiction over the wearer). Additional
OSHA Regulations may also apply for
certain contaminants (See MSA's
Response Respirator Selector).
