Donning The Respirator - 3M SCOTT AIR-PAK X3 PRO Operating & Maintenance Instructions

OPERATING THE RESPIRATOR
You must wear the Air-Pak X3 Pro SCBA over protective garments such as fire fighting turnout gear, but you may
wear it under encapsulating protective garments such as hazardous material (HAZ-MAT) suits. Determine what other
protective gear you will use and don the SCBA and the facepiece accordingly.
If respirator use is expected at temperatures near or below freezing, or if the respirator is to be used after storage at
temperatures near or below freezing, refer to
and supplemental procedures.

Donning the Respirator

Before you don the respirator
•
Check the cylinder gauge. If the cylinder is not full, replace the cylinder before use. A gauge indication of other
than full may indicate an air leak in the cylinder and valve assembly or a malfunction of the gauge assembly.
•
Verify that the cylinder is held securely by the cylinder retention assembly.
•
If a wall storage bracket is used, follow the instructions of the bracket manufacturer for placing your arms
through the shoulder pads and freeing the respirator from the bracket.
•
If the respirator is stored in a hard or soft storage case, place the case on the ground or level surface and open
the case. Secure the regulator in the regulator holder.
To don the respirator
1 Adjust the shoulder pads to their full outward (fully loose) position. Spread the shoulder pads and fold open the
waist pad. Stand the respirator on the cylinder valve with cylinder toward you and the shoulder pads away from
you. See picture A in
2 Pick up the respirator and swing it around behind you as if you were donning a coat. Check to ensure that the
shoulder pads and waist pad are not twisted and lay flat. See picture B in
3 While leaning slightly forward, put on the second shoulder strap. Ensure that both shoulder pads fall into place on
your shoulders. See picture C in
