What is the best technique to use when exiting through restricted passages while wearing an SCBA?

• A. Loosen the SCBA waist strap and remove or loosen one shoulder strap. Maintain control of the regulator side of the SCBA and sling the SCBA to one side to reduce your profile.
• B. Completely remove the SCBA backpack and harness assembly while keeping the facepiece in place and dragging the backpack behind you.
• C. Completely remove the SCBA backpack and harness assembly while keeping the facepiece in place and pushing the backpack in front of you.
• D. Take a deep breath and hold it, doff the SCBA unit, push it ahead of you through the restricted opening.

Answer: (A)

Exiting through tight openings while wearing an SCBA is about getting through with the air supply intact while minimizing the gear’s width. Loosening the waist strap and one shoulder strap creates just enough slack to twist and squeeze through without taking off the whole rig. Keeping a firm hold on the regulator side preserves control of the air supply and prevents the facepiece from being displaced as you maneuver. Slinging the SCBA to one side further reduces your profile and helps you avoid snagging on the opening edges, all while you remain protected and ready to resume full gear once you’re clear.

Removing the backpack and harness entirely, even with the facepiece still on, leaves you without breathable air and complicates re-donning in a hazardous environment. Dragging or pushing the backpack in front or behind through a restricted opening adds unnecessary bulk and risk of snagging, which can trap you or slow you down. Holding your breath and doffing the unit is unsafe because you lose the continuous air supply and expose yourself to contaminants.
