When donning an SCBA, how should the straps on the harness assembly and facepiece be positioned?

• A. Fully extended
• B. Snug
• C. Loosely adjusted
• D. Tightly drawn

Answer: (A)

Starting with the straps fully extended gives you a clean starting point to position the SCBA correctly and reach every adjustment point. With everything lengthened, you can slip the unit on smoothly, align the facepiece for a proper seal, and then pull each strap to achieve an even, secure fit. After the harness and facepiece are in place, tighten the straps so the facepiece sits firmly on the face and the harness rests securely on the shoulders and back. This approach helps prevent strap binding, ensures a reliable seal, and allows comfortable, full-range movement. Loosely adjusted or overly tight straps can lead to movement or discomfort and a poor seal, while fully extended at donning is the correct starting method.
