WARNINGS AND LIMITATIONS—Continued
and care of respirators and in recognizing the hazards associated with
contaminants in the work place.
• Do not use this respirator without the appropriate SPERIAN cartridges
and/or lters securely threaded onto the facepiece. Always read cartridge
labels prior to use and be certain that you have cartridges and/or lters
that will provide the required protection. This respirator must be used for
protection against only those air contaminants listed on the air purifying
cartridge, lter, and/or the NIOSH approval label. Respirators labeled for
protection against particulates only shall not be used for gases/vapors.
Respirators labeled for protection against gases/vapors only shall not
be used for particulates.
• Routinely used respirators must be inspected before and after each use.
Stored emergency respirators must be inspected after each use and at
least once every 30 days. A written record must be kept of inspections
of emergency respirators.
• Do not use this respirator in environments where the concentrations of
contaminants are unknown or are immediately dangerous to life or health
(IDLH). IDLH atmospheres are dened as those which the wearer could not
breathe for short periods, could not escape without the aid of a respirator,
or which have an immediate or delayed adverse effect on health.
• Do not use the respirator if you have health or respiratory problems
as identied by 29 CFR 1910.134, Appendix C, Medical Evaluation
Questionnaire (or by a medical professional). Persons sensitized can
have a severe reaction to chemicals at levels well below accepted
health levels such as the OSHA Permissible Exposure Limit (PEL),
ACGIH® Threshold Limit Value (TLV), or NIOSH Recommended Exposure
Limits (REL). Isocyanates are potent sensitizers. Use positive pressure
supplied air respirators to provide better protection against these
chemicals. Do not use this respirator if you have been sensitized from
previous exposure or believe that you may be sensitive or allergic to any
chemical (e.g., isocyanates, latex, etc.) until you obtain clearance from
a medical doctor.
• Use of components other than those listed on the NIOSH approval label
and in this manual, or as authorized by SPERIAN, or modication of this
respirator in any manner will void the NIOSH certication and invalidates
all SPERIAN’s warranties for the respirator. • This respirator must be
worn and used as specied in SPERIAN’s instructions. No respirator
can provide complete protection from all conditions. Use extreme care
for emergency conditions.
• Some individuals are sensitive to chemicals (e.g., isocyanates, latex,
oil mists, etc.) or may have some type of respiratory disorder (e.g.
asthma, chronic obstructive airway disease, etc.). If you are sensitive
to any chemical or have a respiratory disorder, you may have a severe
reaction at contaminant levels well below accepted health levels, such
as the OSHA Permissible Exposure Limit (PEL), ACGIH®Threshold Limit
Value (TLV), or the NIOSH Recommended Exposure Limits (REL). Many
chemicals (e.g., isocyanates, mercury, etc.) have no physical warning
