DONNING THE FULL BODY/FALL PROTECTION
RESPIRATOR HARNESS
See the DBI/SALA user instructions (SCOTT P/N 89497-01) included
with the full body/fall protection harness for complete information on
application, fitting, maintenance and inspection of the full body/fall
protection harness.
Don the harness in accordance with the DBI/SALA user instructions
(SCOTT P/N 89497-01). Make sure that air supply cylinder, pressure
reducer, air supply hose and regulator do not get tangled in harness.
Ensure that the regulator hose hugs the back by pulling the hose
through the two loops on the right shoulder of the harness to take
up any slack.
On respirators equipped with a neck strap, don the full body/fall
protection harness before placing the neck strap around the neck.
Position the facepiece in a ready to don position using the SCOTT
Neck Strap Assembly.
Position the required length of air supply hose and prepare it for
use by connecting the segments to each other and to the air supply
system. Adjust the pressure at the air supply system to the operating
pressure of the respirator. Repeat this step for each air supply hose
and each air supply system to be used.
Check to be certain that the hand coupling between the cylinder valve
and the pressure reducer is tight and that the breathing regulator purge
valve (red knob on regulator) is closed (knob turned fully clockwise).
Depress the air-saver/donning switch and release. Connect the sup-
ply hose to the airline connection hose on the respirator. There will
be no flow of air from the facepiece at this time.
noTe
IF THE AIR-SAVER/DONNING SWITCH HAS NOT BEEN DEPRESSED
OR IF THE PURGE VALVE IS NOT CLOSED PRIOR TO CONNECTING
THE AIR SUPPLY HOSE TO THE RESPIRATOR, THERE WILL BE A
CONSTANT FLOW OF AIR FROM THE FACEPIECE THAT WILL SUB-
SIDE AFTER THE FACEPIECE HAS BEEN PROPERLY DONNED AND/
OR THE PURGE VALVE HAS BEEN CLOSED.
The user is now in “standby” condition. The respirator is in place but
not in use.
