HOW TO USE SCBA

A self-contained breathing apparatus (SCBA) sometimes referred to as a compressed air breathing apparatus (CABA), or simply breathing apparatus (BA), is a device worn by rescue workers, firefighters, and others to provide breathable air in an immediately dangerous to life or health atmosphere.

Step 1. Lift cylinder with the cylinder valve on top and backplate facing the wearer and raise it over the head. Put on the SCBA on your shoulders like a backpack.

Step 2. Fasten the waist belt and tighten shoulder straps

Step 3. Open cylinder valve by turning handwheel slowly counterclockwise.

Step 4. Check pressure on the gauge.

Step 5. Open all facemask straps fully. Hold breath and place chin into the facemask and pull head harness and straps over the head and tighten all the strap so air won’ leak out your mask.

Step 6. Ensure mask is correctly placed on face with the nose guard on the nose and then tighten upper straps first and then lower ones. Both side straps must be tightened together

Step 7. Start to breathe deep which will actuate positive pressure and then breathe slowly.

Step 8. During venting observe gauge- whistle alarm should sound at preset pressure of 55 bar +/- 5 bar.

Step 9. When gauge indicates zero, hold breath. Face piece should hold onto face indicating positive seal.

Step 10. Open cylinder valve slowly, but fully to pressurize system. Inhale and hold breath. There should be no audible leak.

Step 11. Continue breathing. Expired air should easily flow out of exhalation valve.

Step 12. Press center of rubber cover on demand valve checking supplementary supply.

After Use

1. Press reset lever and switch off.

2. Press and hold down button and remove demand valve.

3. Insert finger behind neck strap and press buckles forward. Pull mask forward and then up and back over the head.

4. Close cylinder valve and remove face piece.

5. Unbuckle waist belt. Remove equipment when shoulder straps loosen.
