Oxygen Position yourself by kneeling on the floor, removing the unit from your belt, and placing it on the floor in front of you. Open the unit by lifting the latch on top and removing the bottom and top covers. Pull the large fluorescent orange oxygen actuator tag down to activate the oxygen. Nosepiece Insert the mouthpiece. Pull the two red nose pads apart and put the nosepiece on so that both nostrils are completely closed.
Straps Put the safety goggles on which are located in the bottom cover.
Adjust the neck strap so the SCSR hangs comfortably, with the canister resting on the chest. Proper adjustment can be checked by raising your head to look up. If you feel a pull on the mouthpiece, the unit is too low on your chest. Wrap the waist strap , which hangs from the bottom of the canister, around the waist and fasten it to the canister on the right side. Cap Replace the hard hat and move out.
