Entering And Exiting The Contaminated Area; Inspection & Maintenance - 3M Versaflo M Serie Instrucciones

7. Complete any final performance checks required according to the User Instructions for your PAPR or
Supplied Air Unit before entering a contaminated area.

Entering and Exiting the Contaminated Area

W WARNING
1. These products meet the requirements of certain industrial eyewear standards and with some
models, certain industrial head protection standards. They do not provide complete head, eye,
and face protection from severe impact and penetration and are not a substitute for good safety
practices and engineering controls. Misuse may result in serious injury or death. For proper
use, see supervisor, refer to the product User Instructions or contact 3M Technical Service.
2. When exposed to eye and face hazards, wear additional eye and/or face protectors appropriate to
the hazard. ANSI Z87.1-2010, incorporated by reference in the OSHA Eye and Face Standard 29
CFR 1910.133, suggests safety spectacles or goggles should be worn in conjunction with loose
fitting respirators if the visor can be raised from the normal position during use. Failure to do so
may result in serious injury.
3. Failure to follow these instructions may reduce respirator performance, overexpose you to
contaminants, and may result in sickness or death.
a. The M-Series Headgear is one component of an approved respiratory protection system. Always read
and follow all User Instructions supplied with your 3M™ M-Series Headgear, PAPR Blower Unit or
Supplied Air Device in order to ensure correct system operation.
4. Do not use the Head, Neck, and Shoulder Cover or non-flame resistant faceseals and shrouds
around high heat, sparks or flames. Misuse use may result in serious injury or death.
5. Failure to follow these instructions may reduce the capability of the M-300 and M-400 Series
Headgear shell to withstand impact and penetration and may result in serious injury or death:
a. Do not use in high heat environments above the recommended maximum temperature.
With the respirator in operation, enter the contaminated area, breathing normally. Keep the air supply
hose or PAPR assembly 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.

W WARNING
3. Leave the contaminated area before reaching inside or removing the headgear. Do not remove
the respirator or reach your hand into the headgear in areas where the air is contaminated. Do not
adjust the airflow deflector while in a contaminated area.
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.
Refer to the Inspection & Maintenance sections of these User Instructions for guidance on how to
properly care for your M-Series Headgear.
INSPECTION & MAINTENANCE
W WARNING
1. Failure to follow these instructions may reduce respirator performance, overexpose you to
contaminants, and may result in sickness or death.
a. 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.
2. Failure to follow these instructions may reduce the capability of the M-300 and M-400 Series
Headgear shell to withstand impact and penetration and may result in serious injury or death:
a. Do not use beyond the maximum life of the product.
Before and after each use, inspect entire headgear for signs of damage or wear including dents, rips, cracks,
color changes, chalking, fading, flaking and penetration. Carefully inspect all headgear components including
the following:
• Visor and visor frame: Look for scratches or other visual distortions that could make it difficult to
see through the visor. Look for signs that the visor has warped or cracked. A warped visor may not fit
properly into the headgear and on the M-400 Series may not seal against the jaw. Ensure the visor stays
firmly in the up (open) and down (closed) positions. Ensure visor buttons are present, firmly secured, and
flush to the visor frame. Examine the visor gasket for tears or other damage. Gasket should be pliable
and not brittle.
• Head suspension: Look for cracks, rips, fading, or other damage. Ensure head suspension ratchet
operates properly. Inspect the web straps for rips, tears, fraying, or fading. Look for worn stitching.
Ensure straps are properly attached.
• Faceseal or inner and outer shroud: Look for tears, holes, stretched elastic, gaps in seams, damage to
stitching or other damage. Examine the gasket for tears or other damage. The gasket should be pliable
and not brittle. Ensure faceseal or inner and outer shroud is securely and properly attached. Inspect the
zipper of the inner shroud and ensure shroud is completely attached to outer shroud.
• Headgear shell: Look for visible damage including dents, cracks, color change, chalking or fading. Any
M-300/M-400 Headgear subjected to impact should be removed from service and replaced even if
damage is not readily apparent.
• Forehead seals: Ensure they are properly and securely attached and are free from damage.
• Breathing tube: Look for tears, holes or cracks. Bend the tube to verify that it is flexible. Ensure the
gasket located in the QRS is present and not damaged. Inspect the gasket located on the bayonet end
of the breathing tube (i.e. end that connects to the air source) for signs of damage. The breathing tube
should fit firmly into the air source connection.
• PAPR blower assembly: Inspect according to the User Instructions for your specific air source.
Inspect date codes on visors, shells, and other plastic components and ensure parts have not exceeded their
maximum life. See Expected Life section of these User Instructions for additional information.
If you discover any signs of wear and/or damage, remove headgear from use and service or
replace as appropriate. Failure to do so may affect respirator performance and reduce the degree of
protection provided.
