Doffi ng The Supplied-Air Respirator
On completion of a work shift, leave the work area wearing the supplied-air respirator with the air still
fl owing.
Once outside the contaminated area the supplied-air respirator should be decontaminated. It can then be
removed by the reverse of the donning process and disconnected from the air supply.
WARNING
LEAVE THE WORK AREA IMMEDIATELY IF:
Any supplied-air respirator or air line hose becomes damaged.
Airfl ow into the respirator slows down or stops.
Air pressure gauge drops below the minimum specifi ed in the breathing air pressure table.
Breathing becomes diffi cult.
You become dizzy, nauseous, too hot, too cold or ill.
You taste, smell or see contaminants inside the air supplied blouse.
Your vision becomes impaired.
Proper work practice requires that you wear the supplied-air respirator until you are outside the
contaminated area. Do not set the respirator down in a contaminated environment because contaminants,
dirt and dust could enter the hood.
