🔍 Key Concepts

• Fireman’s outfit requirements on cargo vessels (see SOLAS Chapter II-2 and 46 CFR Part 96/97 – verify exact current section) • Difference between a canister mask and a self‑contained breathing apparatus (SCBA) • Purpose of a breathing apparatus in an enclosed-space or smoke-filled fire situation

💭 Think About

• Ask yourself: In a shipboard fire with heavy smoke and possibly low oxygen, which device would still provide safe air regardless of the surrounding atmosphere? • Which of the choices is specifically designed as part of a full fireman’s outfit, together with protective clothing, helmet, boots, and safety lamp? • Which items listed are primarily for gas detection or limited filtering, versus those that supply an independent air source suitable for firefighting entry?

✅ Before You Answer

• Verify in the current regulations that a fireman’s outfit must include a breathing apparatus that supplies air independent of the ambient atmosphere. • Check which option is standard equipment in marine firefighting for entering smoke-filled or oxygen-deficient spaces. • Confirm that a combustible gas indicator is for measuring gas concentration, not for breathing protection, and that a simple canister mask has serious limitations in low-oxygen or toxic atmospheres.
