Entering and Exiting the Contaminated Area

W WARNING
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.
4. Leave the contaminated area immediately if any of the following conditions occur:
a. Any part of the system becomes damaged.
b. Airflow into the respirator decreases or stops.
c. Breathing becomes difficult.
d. You feel dizzy or your vision is impaired.
e. You taste or smell contaminants.
f. Your face, eyes, nose or mouth become(s) irritated.
g. You suspect that the concentration of contaminants may have reached levels at which this respirator may no
longer provide adequate protection.
h. The inner shroud on the S-403, S-607, S-707, or S-807 series hood becomes untucked.
Refer to the Inspection & Maintenance sections of these User Instructions for guidance on how to properly care for
your hood or headcover.
INSPECTION & MAINTENANCE
W WARNING
Failure to follow these instructions may reduce respirator performance, overexpose you to contaminants,
and may result in injury, sickness, or death.
• Do not use with parts or accessories other than those manufactured by 3M as described in these User
Instructions or on the NIOSH approval label for this respirator.
The 'in use' life of these products will vary with frequency and conditions of use. Before and after each use, inspect
for signs of damage or wear.
Carefully:
• Examine the condition of the fabric, head suspension, visor, outer shroud, and as applicable, inner shroud, collar, or
elasticized faceseal. Check that there are no cracks, rips, dents, holes, tears, or other damage.
• Look closely at the stitching. Ensure stitching is intact and there is no unraveling or gaps in the seams. There should
be no tears or holes that could permit contaminated air to enter the hood or headcover.
• If using the S-800 series hood, closely inspect the sealed seams for rips, holes, tears, or other damage. Ensure side
ties are present and undamaged.
• Look for scratches or other visual distortions that could make it difficult to see through the visor.
• Examine the head suspension for cracks or other damage.
8
• Examine the entire breathing tube. Look for tears, holes, cracks distortions, or any other sign of wear or damage.
Bend the tube to verify that it is flexible. Ensure the gasket located in the QRS (i.e. the end connection to headgear)
is present and not damaged. If using a BT-Series breathing tube, inspect the gasket located on the bayonet end of
the breathing tube (i.e. the end that connects to the air source) for signs of damage. The breathing tube should fit
firmly into the air source connection.
If you discover any signs of wear and/or damage, discard the component and replace it with a new one.
Failure to do so may affect respirator performance and reduce the degree of protection provided, and may
result in sickness and death.

REPLACEMENT PARTS AND ACCESSORIES

W WARNING
Failure to follow these instructions may reduce respirator performance, overexpose you to contaminants,
and may result in sickness or death.
• Do not use with parts or accessories other than those manufactured by 3M as described in these User
Instructions or on the NIOSH approval label for this respirator.
