III. DESCRIPTION
This SPERIAN air purifying respirator consists of a
full facepiece made of pliable silicone rubber with two
threaded connectors for attaching particulate lters, gas
and vapor cartridges, and cartridge/lter combinations
as required for specic contaminant protection.
WARNING
• The employer is responsible for establishing that this
respirator is suitable for the user’s applications.
• This facepiece must be worn and used as specied in
SPERIAN’s instructions.
• Your SPERIAN respirator has been constructed of
materials selected for their performance, safety,
and durability. However, all materials have exposure
limitations to extremes of heat and cold or to the many
chemicals in use today, and could be degraded by
exposure beyond their limitations, creating conditions
in which this SPERIAN equipment would be dangerous
to use.
• Before entering an environment while wearing SPERIAN
equipment, you must conduct safe, scientic tests
to determine if the environment could render the
equipment unsafe. Results of this testing should be
well documented. Seek the help of a certied safety
professional or industrial hygienist. DO NOT USE this
equipment if the user would be endangered in any way
through environmentally induced degradation of the
materials

damage to property, personal injury, or death in which
environmental exposure is a contributing factor.
• Do not use this respirator in environments where the
concentrations of contaminants are unknown, or where
the atmosphere is immediately dangerous to life or
health (IDLH). IDLH atmospheres are dened as:
1. Those which the wearer could not breathe for short
periods.
2. Those from which the wearer could not escape
without the aide of the respirator.
3. Those which have an immediate or delayed adverse
effect on health.
• Never use this respirator without appropriate SPERIAN
cartridges/lters identied on the NIOSH approval label
securely threaded onto the face piece.
• This respirator does not supply oxygen and must not be
used in the atmospheres containing less than 19.5%
oxygen by volume.
• Our engineers cannot predict what will happen to this
equipment in every potential environment. Materials
can be chemically attacked if exposed to the wrong
environment and may exhibit excessive corrosion or
other forms of damage. Permeation of gases and liquids
through the materials could be excessive. Extreme of
temperature might cause thermal degradation. Each of
these things, or a combination of them, could crated
conditioning with this SPERIAN equipment would be
dangerous to use.
• All persons using this SPERIAN breathing apparatus
must be amde aware of its limitations.
We cannot be responsible for any damage to property,
personal injury, or dath in which environmental
exposure is a contributing factor.
• Always read cartridge labels prior to use to be certain
that you have cartridges and/or lters that will provide
the required protection. Cartridges/lters labeled for
protection against particulate only shall not be used
for gases/vapors, and cartridges/lters labeled for
protection against gases/vapor only shall not be used
for particulates:
• Immediately return to a non-contaminated area if:
a. You taste or smell contaminates , or if your eyes,
nose, or throat become irritated. blasting, underwater
diving, or interior structural re ghting.
b. Breathing becomes difcult.
c. The air you are breathing becomes uncomfortably
warm.
d. You feel nauseous or dizzy.
• This respirator does not protect exposed areas of the
body. Some contaminates can be absorbed directly
through the skin while other may irritate exposed area.
• This respirator must not be used for abrasive blasting,
underwater diving, or interior structural re ghting.
WARNING
• Do not use this respirator at temperatures below -30°F
(-1°C) or above 130°F (71°C). Do not wear this respirator
if a satisfactory t, as determined by a qualitative or
quantitative t test, cannot be obtained. See ANSI
Z88.2 1992 and OSHA Standards for Asbestos and
Lead. Beards, stubble, or sideburns will prevent a good
facepiece seal. Do not use this respirator unless you
are clean shaven. Absence of one or both dentures can
seriously affect the t of the facepiece.
• No respirator can provide complete protection from all
conditions. Use extreme care for emergency operations.
Do not use this respirator for applications involving
exposure to high heat or direct ame.
• Accessories not offered by SPERIAN may degrade
performance, and will void NIOSH certication.
• NEVER use this respirator without SPERIAN cartridges
or lters securely threaded onto the facepiece. This
respirator must be used in conjunction with a written
respirator program meeting the requirements of the
OSHA Standard for Respiratory Protection, 29 CFR
1910.134, available from the U.S. Department of Labor,
Occupational Safety and Health Administration. The
program must include procedures for evaluating air
contaminants and selecting appropriate respirators,
procedures for proper use of respirators, procedures
for testing the facepiece-to-face t of respirators,
procedures for cleaning, disinfecting, inspecting,
maintaining, and storing respirators, procedures for
determining if workers are physically and medically
capable of wearing respirators, and procedures for
training employees in the use of respirators and in
recognizing the hazards associated with contaminants
in the work place. When used with a written respirator
program, this respirator will reduce, but not eliminate
the inhalation of contaminants.
• SPERIAN respirators, accessories, and associated
equipment should not be used in atmospheres which
may contain contaminant concentrations above the
lower explosive level (LEL). Intrinsic safety certication
of electronic components does not eliminate potential
danger from ignition in these atmospheres.
