What IS NOT a physical limitation of personnel working in a positive pressure SCBA?

• A. Mobility restrictions
• B. Vision limitations
• C. Height and weight
• D. Fatigue from weight

Answer: (C)

When you wear a positive-pressure SCBA, the gear introduces real physical demands: the bulk and weight of the backpack and tank can limit mobility, the mask and facepiece can reduce peripheral vision, and carrying the extra weight plus breathing through the system can cause fatigue. Height and weight, in themselves, do not define a limitation of using the SCBA. The equipment is designed to fit a range of body sizes, and any restriction tends to come from fit and comfort, not from a person’s height or weight. So, height and weight aren’t the physical limitations of operating in an SCBA—the other factors are.
