higher. If the hazard ratio is less than 20, you
may use a full facepiece respirator with a filter
efficiency of 95% or higher. If the hazard ratio is
less than 100, you may use a full facepiece res-
pirator with a filter efficiency of 99% or higher. If
the hazard ratio is greater than 100, you must
use another type of respirator.
N-series filters must only be used for non-oil
containing aerosols or particulates. R or P-
series filters can be used if the atmosphere
contains oil (e.g., lubricants, cutting fluids,
glycerin, etc.). An R-series filter used in an oil-
containing atmosphere must be replaced after
each 8-hour shift. A P-series filter can be used
for more than one 8-hour shift. Please refer to
Section VIII, Part A.6, Chemical and Particulate
Filter Service Life and Replacement, for impor-
tant additional information. Refer to the NIOSH
publication Guide to the Selection and Use of
Particulate Respirators Certified Under 42CFR
84 for additional guidelines on use limitations
for filters.
WARNING
Filters improperly used or improperly
assembled to the facepiece could cause
leakage, which could lead to personal
injury, illness, or death.
c. Cartridge/Filter Installation
Ensure that you have the correct cartridge and/
or filter type for the contaminants in your work
area. If you are not sure, consult your supervi-
sor or safety professional.
Install cartridges and filters by threading
i.
them onto the facepiece connectors and
hand tightening. Do not overtighten.
If using filter pads, insert the appropriate
ii.
pad into the filter retainer so that the side
stamped with the model number will face
towards the facepiece when installed.
Completely snap the filter retainers onto
the cartridges or filter holders.
Inspect the filter through the retainer to
iii.
ensure that the entire edge of the filter is
making contact with the retainer and the
filter is not bunched or folded. The outer
edge of the pad must be compressed be-
tween the top edge of the cartridge or filter
holder and the inner sealing rings of the
retainer. Install filter holders in the same
manner as cartridges.
WARNING─Continued
for more than 8 hours or one shift,
even though the calculated service
life estimate is greater that 8 hours or
one shift. These contaminants can mi-
grate through the canister even when
the canister is not in use (e.g., over-
night) and collect in the facepiece.
● Do not use this respirator without the
appropriate SPERIAN cartridges and/
or filters securely attached onto the
facepiece. Always read cartridge la-
bels prior to use and be certain that
you have cartridges and/or filters
that will provide the required protec-
tion. This respirator must be used
for protection against only those air
contaminants listed on the air purify-
ing cartridge, filter and/or the NIOSH
approval label. Respirators labeled
for protection against particulates
only shall not be used for gases/va-
pors. Respirators labeled for protec-
tion against gases/vapors only shall
not be used for particulates.
● This respirator does not supply ox
-
ygen. Do not use the respirator in
atmospheres containing less than
19.5% oxygen by volume.
● Failure to comply with this warning
may lead to personal injury, illness,
or death.
1. Installing Chemical Cartridges and Particulate
Filters
a. Mercury Vapor Cartridges
Special or Critical User’s Instructions: The mer
-
cury vapor cartridges incorporate passive end-
of-service-life indicators (ESLI). Each ESLI,
yellow in color when new, turns gray when
exposed to mercury vapor. Do no use these
cartridges unless you can distinguish between
the safe and discard colors of the ESLI. The
indicators must be visible when wearing the
respirator without having to manipulate either
the facepiece or the indicator. If the indicators
cannot be seen, do not wear the respirator. The
cartridges must be replaced when the ESLI
change color from yellow to gray, when the
ESLI become dirty or damaged, after 30 days
of use, or if removed from their original packag-
ing and not used within 30 days. Never enter
or remain in a hazardous atmosphere if one or
more of the ESLI is gray.
b. Particulate Filters
Before using a particulate filter, you must con
-
firm the atmosphere is non-IDLH and not oxy
-
gen deficient, the contaminant is a particulate
hazard, and you must determine the hazard ra-
tio (hazard concentration/exposure limit). If the
hazard ratio is less than 10, you may use a half
mask respirator with a filter efficiency of 95% or
