Entering And Exiting The Contaminated Area - 3M Versaflo M Serie Manual De Instrucciones

b. M-100 Series Headgear Only: The fabric straps of the M-100 can be adjusted by sliding the
blue strap lock located on the center strap (Fig. 3). Sliding the buckle towards the rear of the
headgear tightens the straps and will raise the height of the headgear on the head. Sliding the
buckle towards the front of the headgear loosens the straps and will lower the height of the
headgear on the head.

5. Lower the visor into the down position.
a. M-100: Pull down on the loop located on the faceseal. Ensure the visor is fully down and covering
your face. The headgear should sit level on your head with the faceseal gently hugging your face.
If using the M-985 Earmuff Assembly or M-976 Head, Neck, and Shoulder Cover, ensure it does
not interfere with the faceseal. The elasticized edge of the faceseal should come into contact with
the skin under the chin and around the jaw.
b. M-300: Pull down on the loop located on the faceseal. Ensure the visor is fully down and covering
your face. The headgear should sit level on your head with the faceseal gently hugging your face.
If using the M-985 Earmuff Assembly or M-976 Head, Neck, and Shoulder Cover, ensure it does
not interfere with the faceseal. The elasticized edge of the faceseal should come into contact with
the skin under the chin and around the jaw.
c. M-400: Ensure visor is firmly closed (completely latched) in the down position. You should hear
an audible "click" when it is fully closed. Tighten the adjustable cord on the inner shroud until
there is less than a two finger gap between your skin and the inner shroud. Leave the outer
shroud draped over your shoulders.
6. If needed, adjust the airflow inside the headgear for wearing comfort. To adjust, raise the visor into
the up (open) position. Locate the blue air deflector in the front of the headgear and rotate. Fig. 4
shows where the air deflector is located. There are two positions. Adjust fully open for more airflow
across the face or partially closed to re-direct a portion of the air towards the visor. After adjusting
the air deflector, lower the visor back into the down position.
note: Do not adjust the air deflector while in a contaminated area.

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

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 Z87.1-2003, 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.
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.
