13. 2-4-13 Donning Procedures n Spectacles (ARS) –can regular spectacles be used? n Skull cap –to help absorb sweat from the head –may require additional help to put hood on over

14. 2-4-14 Donning Procedures cont n Mask –Hood outlet valve open –Ensure pusher fan is “ON” WARNING When donning the mask do not overextend or damage the neck seal. Do not wear watches or stone rings while donning. n Respirator Functional Test

15. 2-4-15 Respirator Function Test n Don hood n Don helmet n Pusher fan on n Connect toggle harness assembly to helmet and adjust n Pinch-off hood inlet hose –Air vents through hood outlet valve n Wearer holds breath and notes if air is leaking from around the mask –Leakage evident readjust toggle harness. If still present and can’t fix via toggle harness replace with a smaller or larger mask.

16. 2-4-16 Donning Procedures cont n Once mask and hood are donned tuck shoulder skirt into flight suit –this is why you must don mask prior to torso harness and/or survival vest CAUTION Ensure shoulder skirt material does not catch in the slide fastener and neck bellows remains outside of flight suit collar. Be sure shoulder skirt is not tucked in too tightly, as this can restrict mobility.

17. 2-4-17 This. Not this

18. 2-4-18 Donning Procedures cont l Helmet –Turn pusher fan “OFF” –Sprinkle talc on exposed hood covering the head * –Don fore to aft –Attach chin/nape strap –Turn pusher fan “ON” –Check visor operation * NOTE A very light dusting of talc on the outside of the hood can be used to facilitate helmet donning.
