Inspection And Performance Check; Donning - 3M Powerflow Instrucciones

Charging Battery pack with Smart Charger (520-03-73, 520-03-72, and 520-01-61):
Charge in an area free of combustible material and readily monitored.
• A new or completely exhausted battery pack should be charged for 16 to 24 hours.
• Place the charging station horizontally on a flat surface and plug the station AC power cord into a regulated
120v-60Hz outlet. The green LED light will turn on.
• Insert the charging lead into the battery pack.
• The LED will turn off, indicating that the battery pack attached is being charged in a high rate mode.
• After approximately eight hours (depending on the amount of charging required) the LED will turn back on,
indicating that the charger has switched to a trickle rate mode. For Canadian chargers, when in trickle mode, the
LED light will cycle on and off every 3-5 seconds.
To maximize battery pack life, these guidelines should be followed:
• Charge 3M™ battery packs before they are completely discharged. Damage may occur if the battery pack is
completely discharged ("deep discharged") frequently.
• 3M™ battery packs may be charged any time during the discharge cycle. Unlike some NiCad batteries, 3M™
battery packs do not develop a "memory."
• Do not allow water to enter the battery pack.
• Always charge batteries at a temperature between 50° and 80°F (10° and 27°C). At higher temperatures, the
battery pack may not accept a full charge. If a battery pack feels hot, let it cool for 1/2 hour before charging.
• Batteries may be left on trickle rate mode to maintain optimum capacity for up to 30 days. Batteries should not
be stored long term connected to the charger. Without periodic charging, a NiCad battery pack in storage loses
approximately 1% of its charge each day. Infrequently used battery packs should be fully charged, initially, then
charged overnight once per week or one hour each day to maintain a full charge. Batteries subjected to prolonged
storage (longer than 6 months) may lose their capacity to hold a full charge.
• For infrequently used batteries, battery pack capacity should be checked regularly by running the PAPR motor
blower unit and noting how long the required airflow is maintained at or above the proper level using the air flow
indicator. Several charge/run-down cycles may restore battery pack capacity.
• Do not charge multiple battery packs in an enclosed cabinet without ventilation.

INSPECTION AND PERFORMANCE CHECK

Before each entry into a contaminated area, the following inspection must be performed to help ensure proper function
of the respirator system. Refer to the Assembly subsection of these User Instructions for proper assembly procedures.
Replace any damaged or missing parts with 3M™ Powerflow™ replacement parts before proceeding.
1. PAPR System: Visually inspect the PAPR system.
• Head harness straps are not torn.
• Visor is not cracked.
• Inhalation valves are not worn, torn, bent, dry, or sticky.
• There are no holes in the facepiece material.
• Motor blower is intact with no cracks or other damage.
• No other signs of damage or defect are noted.
2. Bayonet ports: Ensure these two ports on either side of the facepiece are closed using 6880 bayonet caps and 6895
inhalation port gaskets.
3. Battery pack: Confirm battery pack is fully charged and charge is sufficient for duration of the work period. Ensure
that the clothing clip and screw are in place. If they are missing, the PAPR system is not intrinsically safe.
4. HE filter: Inspect the filter and gasket for tears, cuts, distortion. Replace gasket or filter if any damage is noted.
Ensure the HE filter is 3M part number 450-01-01, that an HE filter is appropriate for the environment of its intended
use and it is properly installed.
5. User Performance Check: A user performance check must be performed prior to each use.
• Check the air flow as follows:
• Ensure the ball in the 520-01-21 airflow indicator moves freely.
• Disconnect the motor blower from the facepiece.
• Confirm that the HE filter and fully charged BP-17IS battery pack are connected to the motor blower
• Insert the base of the airflow indicator into the outlet side of the motor blower as shown below. The word
"Powerflow" on the airflow indicator should be right side up. If the airflow indictor seems excessively wobbly in the
motor blower, the indicator may be upside down.
• Turn the battery pack switch to the ON position.
• Hold the motor blower so the airflow indicator is in a vertical position.
• Ensure the center of the airflow indicator float is at or above the two horizontal arrows (4 CFM) on the airflow
indicator just below the word "Powerflow". If the float fails to reach this mark, substitute a freshly charged battery
pack and/or install a new filter. Replace the plug and screw cap on the old filter and dispose of it in accordance with
federal, state and local laws and regulations.

Failure to pass a user performance check and inspection or to complete all necessary repairs before use may
adversely affect respirator performance and result in sickness or death.
NOTE: Before assigning any respirator to be worn in a contaminated area, a qualitative or quantitative fit test must be
performed per OSHA Standard 1910.134, CSA Standard Z94.4 or the requirements of the authority having jurisdiction in
your region.

DONNING

1. Verify the motor blower assembly and filter is properly attached to the facepiece. Refer to the Assembly section of
these User Instructions.
2. Clip the battery pack to the waist belt. If this system will be exposed to water, the battery pack must be placed in the
water-repellent battery pack cover (529-01-56R01) before use to avoid corrosion, deterioration, and possible battery
pack failure.
NOTE: If intrinsic safety is required, the battery pack cover cannot be used as a replacement for a missing
battery pack clothing clip and screw. If the clip and screw are missing, they must be replaced to maintain the
intrinsic safety rating.
3. Fully loosen all four head straps. Place the harness at the back of the head and position facepiece over the face.
5. Pull the ends of the four straps to adjust tightness, starting with the neck straps first, then the forehead straps. Do not
over tighten the straps.
6. Perform a positive and negative pressure user seal check each time the respirator is donned. See User Seal Check in
this section.
7. Connect PAPR power cord to the battery pack.
8. Turn the system on.
If skin rash or irritation results following use of this facepiece, discontinue use and consult a safety professional and/or a
physician.
User Seal Check
Always check the respirator-to-face seal before each entry into a contaminated area.
Positive Pressure Seal Check
1. Place and hold a piece of paper over the 6882 DIN exhalation valve cover and filter inlet and exhale gently.
2. If facepiece bulges slightly and no air leaks are detected between your face and the facepiece, a proper fit has been
obtained.
3. If faceseal air leakage is detected, reposition respirator on your face and/or readjust tension of the straps to eliminate
leakage. Repeat above steps.
If you cannot achieve a proper seal, DO NOT enter the contaminated area. See your supervisor.
Negative Pressure Seal Check
1. Cover the HE filter inlet with your palm. Inhale gently.
2. If the facepiece collapses slightly, and no air leaks between the face and facepiece are detected, a proper fit has
been obtained.
3. If faceseal air leakage is detected, reposition the respirator on the face and/or readjust the tension of the straps to
eliminate leakage. Repeat above steps.
If you cannot achieve a proper seal, DO NOT enter the contaminated area. See your supervisor.
