Inspection - 3M Versaflo TR-800 Series User Instructions

INSPECTION

Failure to follow these User Instructions may reduce respirator performance, overexpose you to contaminants,
and may result in injury, 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.
b. The 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 Assembly is one component of an approved
respiratory protection system. Always read and follow all User Instructions supplied with your 3M™ Headgear and
other system components in order to ensure correct system operation.
c. Do not turn off the motor/blower, remove the facepiece or headgear, or reach your hand into the headgear while inside
the contaminated area. This could allow contaminants to enter the respirator and may result in sickness or death.
Before each entry into a contaminated area, the following inspection must be performed to help ensure proper function of
the respirator system. Respirator systems are intended to help reduce exposures to certain contaminants and should always
be handled with care and fully inspected prior to use. Refer to the specific assembly subsection of these User Instructions for
proper assembly procedures.
1. PAPR system:
Closely inspect the entire PAPR system including the motor/blower, cover, filter/cartridge, breathing tube, battery, belt,
headgear. Pay particular attention to component connection points for wear or damage. If parts are missing or damaged,
replace them only with 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 Replacement Parts before proceeding.
2. Filter/cartridge:
• Closely inspect filter/cartridge plastic housing including the corners and latches, outer rectangular barrier, and inner
circular filter seal gasket for cracks, tears, cuts, distortion, indentations or debris. Replace filter/cartridge if damaged.
If the filter/cartridge has been mishandled or dropped, re-inspect fully. If you have any questions, contact 3M
Technical Service for guidance.
• Ensure the filter/cartridge is properly installed in the PAPR unit.
• If the filter cover is used, the filter/cartridge label must be visible in the filter cover window (Fig. 13).
• If sparks or other hot particles are present, the spark arrestor with filter cover must be in place in front of the
filter/cartridge and prefilter (if used). Failure to use the spark arrestor when needed may allow the filter to catch fire,
or be damaged and allow contaminants to enter the respirator.

3. Battery pack: Confirm that the battery pack is fully charged or charge is sufficient for duration of the work period. Ensure
plastic surrounding electrical contact pins are intact. The battery pack must be connected to the motor/blower. Gently tug
on the battery to ensure secure connection.
4. Breathing tube: Examine the entire breathing tube for tears, holes or cracks. Bend the tube to verify that it is flexible.
Ensure the gaskets located at both ends of the breathing tube (i.e. headgear and air source connections) are present and
not damaged. The breathing tube should fit securely into the air source connection.
5. Headgear: Follow the User Instructions supplied with your 3M headgear to ensure correct system operation.
6. Airflow check:
The TR-800 is pre-calibrated to ensure required airflow. However, the 3M™ Airflow Indicator TR-971 must be used to
verify minimum required airflow is attained prior to each day's use. The TR-800 compensates for changes in air density,
which is affected by elevation and air temperature. During use, if you suspect the TR-800 is not delivering a minimum
of 6 cfm (170 lpm), exit the contaminated area, see your supervisor, and recheck the airflow with the 3M™ Airflow
Indicator TR-971. The airflow is checked with your current filter installed.
• Ensure float ball in the TR-971 moves freely in the tube and the gasket at the bottom end of the tube is in place.
• Insert the TR-971 into the outlet of the TR-800 motor/blower unit. If the breathing tube is in place, it must be
removed to allow the airflow indictor to be inserted (Fig. 14-1).
• Turn the motor/blower unit on by pressing and holding the power button for 1 second. Run the 3M™ Versaflo™
Powered Air Purifying Respirator TR-800 for up to 1 minute to allow the airflow to stabilize.
