Cautions and Limitations
A. Not for use in atmospheres containing less than 19.5%
oxygen.
B. Not for use in atmospheres immediately dangerous to
life or health.
C. Do not exceed maximum use concentrations established
by regulatory standards.
F. Do not use respirator if airflow is less than four cfm
(115 lpm) for tight fitting face pieces or six cfm
(170 lpm) for hoods and/or helmets.
I. Contains electrical parts which have not been evaluated
as an ignition source in flammable or explosive
atmospheres by MSHA/NIOSH.
J. Failure to properly use and maintain this product could
result in injury or death.
L. Follow the manufacturer’s user instructions for
changing cartridges and/or filters.
M. All approved respirators shall be selected, fitted, used
and maintained in accordance with MSHA, OSHA and
other applicable regulations.
N. Never substitute, modify, add or omit parts. Use only
exact replacement parts in the configuration as
specified by the manufacturer.
O. Refer to User’s Instructions, and/or maintenance
manuals for information on use and maintenance of
these respirators.
P. NIOSH does not evaluate respirators for use as surgical
masks.
Use strictly in accordance with instructions, labels and
limitations pertaining to the PA20 respirator.
1. The PA20 respirator does not supply oxygen. Use only
in adequately ventilated areas containing at least
19.5% oxygen.
2. Do not use when concentrations of contaminants are
immediately dangerous to life or health.
3. Do not use these respirators for respiratory
protection during abrasive blasting.
4. Do not use in circumstances where the airborne
concentration level of contaminant exceeds maximum
use concentration for this type of respirator as
established by regulatory standards.
5. Leave area immediately if:
• Breathing becomes difficult
• Dizziness or other distress occurs
• You taste or smell the contaminant
• Unit becomes damaged
• Battery alarm sounds
6. This apparatus must not be worn with the blower unit
switched off. If the blower switched off, a rapid build-
up of carbon dioxide and depletion of oxygen may
occur, which could result in death or serious injury.
7. Never alter or modify this respirator. Use only NIOSH
approved PA20 components and replacement parts
for this respirator.
Failure to follow these warnings could result in death or
serious injury.
