Entering and Exiting the Contaminated Area
1. Failure to follow these instructions may result in serious injury.
a. Do not use these products for eye and face protection. When exposed to eye and face hazards
(e.g. impact hazards), select and wear appropriate protection.
b. Do not use these products around heat, flames, or sparks. Select and wear appropriate protection
when exposed to sparks and/or flames. In case of intended use in explosive atmospheres, contact
3M Technical Service.
2. The S-Series hoods and headcovers are one component of an approved respiratory protection system.
Always read and follow all User Instructions supplied with your 3M PAPR Blower Unit or Supplied Air
Unit in order to ensure correct system operation. Failure to do so may reduce respirator performance,
overexpose you to contaminants, and may result in injury, sickness, or death.
With the respirator donned correctly and in operation, enter the contaminated area breathing normally. Keep
the PAPR assembly or air supply hose away from equipment, vehicles, and other physical and chemical hazards.
1. Airborne contaminants which can be dangerous to your health include those that are so small you may not
be able to see or smell them.
2. Do not wear this respirator to enter areas where:
a. Atmospheres are oxygen deficient,
b. Contaminant concentrations are unknown,
c. Contaminant concentrations are Immediately Dangerous to Life or Health (IDLH),
d. Contaminant concentrations exceed the maximum use concentration (MUC) determined using the
Assigned Protection Factor (APF) for the specific respirator system or the APF mandated by specific
government standards, whichever is lower. See APF section of these User Instructions.
3. Leave the contaminated area before reaching inside or removing the hood or headcover. Do not remove the
respirator or reach your hand into the hood or headcover in areas where the air is contaminated.
