What is the correct sequence for donning an SCBA and securing the harness?

• B. Put on the backframe, position the cylinder, slide arms through shoulder straps, connect the waist belt, and tighten straps unevenly
• C. Put on the backframe, connect the waist belt, slide arms through shoulder straps, position the cylinder, and tighten straps evenly to secure
• D. Put on the facepiece first, then the backframe and finally the cylinder, ignoring fit

Answer: (A)

Donning and securing an SCBA harness is about building a stable, well-aligned foundation before adding the cylinder. Start by putting on the backframe so you have a rigid support to anchor every strap. Next, slide your arms through the shoulder straps so the backframe sits flat against your back and the straps lay correctly without twists. Then fasten the waist belt to lock the frame in place and help distribute the load around your hips, which keeps the unit from shifting as you move. Position the cylinder on the back so the weight is balanced and the valve is accessible for use. Finally tighten the straps evenly, applying uniform tension to avoid pressure points and ensure a secure, stable fit.
