Which of the following is required to be included in the fireman's (emergency) outfit?

Correct Answer: Option C — Self-contained breathing apparatus

46 CFR Subchapter J and SOLAS regulations mandate that fireman's outfits include a self-contained breathing apparatus. This equipment is vital for firefighting and rescue operations in smoke-filled or oxygen-deficient engine room spaces, ensuring the safety of the fire party while they perform emergency duties under hazardous conditions.
