WARNING-Continued
• You must immediately leave the contaminated area
if you taste or smell contaminants, or if your eyes or
throat become irritated. Replace the canister before re-
entering the contaminated area.
• You must replace the canister when breathing becomes
uncomfortable or difcult. As particulates collect on the
lter surface, the breathing resistance of the gas mask
increases. If you wait too long to replace the canister,
particulates may leak past the face seal instead of being
collected on the lter; therefore, SPERIAN recommends
that the canister be changed at least daily.
• Establishing the canister service life for mixtures of
contaminants is a complex task and one that requires
considerable professional judgement to create a
reasonable change schedule. OSHA provides a “rule-of-
thumb” method for determining the canister service life
for mixtures. The method addresses two situations. The
rst is where the individual compounds of the mixture
have similar breakthrough times (e.g., within one order
of magnitude). In this case OSHA recommends adding
the concentrations of all the components of the mixture
to determine a “total concentration”, then determine the
mixture service life by applying the total concentration
to the component with the shortest service life. The
second is where the individual compounds have
breakthrough times that vary by 2-orders of magnitude
or greater. In this case, OSHA recommends the mixture
service life be based on the contaminant with the
shortest breakthrough time. The OSHA rule-of-thumb
methods may not be applicable for all mixtures. In
some cases the actual mixture service life may be
much lower than the one calculated. For this reason,
SPERIAN recommends using experimental methods. If
you are unsure how to determine the canister service
life for mixtures please contact SPERIAN.
• Failure to comply with this warning may lead to serious
personal injury, serious illness, or death.
The gas/vapor service life depends on the user’s breathing
rate, the characteristics of the contaminant, and environmen-
tal conditions such as temperature and humidity. A saturated
canister will leak trace amounts of contaminant to the wearer,
which may be detected by odor, taste, and/or irritation. Re-
place the canister in accordance with an OSHA compliant
canister change-out schedule or earlier if you detect the con-
taminant by that the canister service life for mixtures be de-
termined smell, taste, or irritation, or if they show any signs
of damage. The canister should always be replaced in ac-
cordance with schedules established by regulatory agencies,
and disposed of in accordance with Federal, state, and local
guidelines. Always replace the canister with one taken from a
sealed package.
The particulate lter service life depends on the user’s breath-
ing rate, the characteristics of the contaminant, and envi-
ronmental conditions such as humidity. The particulate lter
used in the canister is NIOSH approved for long duration use
against any type of particulate. When used in oil-containing
(e.g., lubricants, cutting uids, glycerin, etc.) or non-oil-con-
taining atmospheres, the canister must be replaced immedi-
ately whenever it is damaged, soiled, soaked with liquids such
as water or alcohol, the canister appears to be suspect in any
manner, or when the user notices an increase in breathing
resistance such that the gas mask becomes uncomfortable
to wear.
If none of the above occurs and there is a respiratory protec-
tion program per OSHA 29 CFR 1910.134 in place, then the
canister may be used continually, but only for a maximum of
30 days or 40 hours, whichever comes rst. However, the ser-
vice time can be extended if lter performance to 42 CFR Part
84 can be demonstrated. Whether used in oil-containing or
non-oil-containing atmospheres, SPERIAN recommends the
canister be replaced daily because the user may be unable
to detect small defects in the canister lter resulting in a loss
of lter efciency, and the determination of when breathing
resistance becomes too uncomfortable is subjective.
