SCBA (Self-contained breathing apparatus) is used to protect workers against oxygen deficiency, dust, Asbestos, gases (especially H2S) and vapours at refineries, aboard vessels, at fire and in tunnels.
In this video, I have demonstrated the proper way to don (wear) & doff (remove) SCBA by COAT method.
DONNING steps:
1. Place the pressurized cylinder on the ground in reverse way.
2. Visually check SCBA assembly. Loosen all straps.
3. Don like a COAT grasping backframe with both hands on either side of the cylinder. (Overhead method may bring head injury so practice is needed)
4. Tighten all straps (shoulder, waist and chest).
5. Extent air pressure gauge and remove if any air is inside demand valve hose (using bypass valve).
6. Open cylinder fully – for supply of pure air.
7. Don facepiece and check seal tightness.
8. Now connect both assemblies.
9. Don safety gloves and helmet.
DOFFING steps:
1. Unclick regulator
2. Remove gloves and Helmet/hood
3. Doff facepiece
4. Doff all the straps and cylinder harness assembly.
5. Place SCBA back at safe place.
For Emergency Escape there's another option, see below:
