Which is true regarding SCBA?

• A. Tighten the Top straps of the SCBA Face-piece first
• B. All SCBA Face-pieces must be fit-tested
• C. Hoods should be worn under the SCBA Straps and Facepiece
• D. Positive pressure should not be tested by breaking the regulator seal

Answer: (B)

Ensuring a proper seal on a tight-fitting respirator is essential because any gap can let contaminants in and compromise protection. For SCBA facepieces, fit testing verifies that the particular facepiece model and size actually seals on your face during real-use movements, not just when you’re standing still. This is required by regulations and department policy, and it applies to every wearer who uses SCBA. Because of this, all SCBA facepieces must be fit-tested to confirm they provide the intended protection for each individual. Other statements don’t reflect this protective-practice. A might describe a donning sequence, but strap-tightening order isn’t the standard guarantee of a proper seal. C’s hood placement and D’s testing method aren’t the established fit-testing requirements, which focus on verifying a reliable seal for the wearer.
