Rescue personnel entering a space after low and medium expansion foam discharge must use lifeline and what equipment?

• A. Hard hat
• B. Safety glasses
• C. SCBA
• D. Flame-resistant gloves

Answer: (C)

In a space where foam has just been discharged, the atmosphere can be hazardous or oxygen-deficient, with potential vapors from the foam or residues. Entering safely requires respiratory protection that does not depend on the surrounding air, which is provided by a self-contained breathing apparatus. The SCBA delivers breathable air to the wearer, protecting the lungs from inhaling contaminants and from oxygen deficiency in the space. The other options don’t address respiratory safety. A hard hat protects the head, safety glasses shield the eyes, and flame-resistant gloves protect the hands, but none provide the essential breathing protection needed for confined-space entry after foam discharge.
