Bullard PA1 Manuel D’Utilisation

TM

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.
