Why does AFF training cover fires involving specific cargo and material types (such as flammable liquids, electrical fires, and metal fires) separately rather than teaching a single universal fire-fighting approach?

A. Fire type classification is a purely academic distinction with no practical bearing on real extinguishing decisions

B. All fire types respond identically to water and a universal approach is always safe and effective

C. Only shore-based industrial fire services need to consider fire type; maritime fires are always a single uniform category

D. Different fire types require genuinely different, sometimes opposite, extinguishing approaches — water on certain metal or electrical fires can make things significantly worse or create new hazards (such as electric shock or violent metal-water reactions), so correctly identifying the fire type before choosing a response is a critical, trained skill

A. AFF and basic fire fighting cover identical content, simply repeated at greater length

B. AFF is required for every single seafarer regardless of muster list role, with no distinction from basic training

C. Basic training covers initial detection, raising the alarm, and using a portable extinguisher on a small incipient fire, while AFF covers organising and leading a coordinated fire-fighting response — including breathing apparatus (BA) entry, ventilation control, boundary cooling, and command of a fire party — required for designated officers and fire team members

D. AFF only applies to passenger vessels and has no relevance to cargo ships

A. Air supply checks are only relevant after the team has already entered the affected space

B. BA entry teams should enter without informing the bridge or control point, to avoid causing alarm

C. No formal entry control or time logging is necessary as long as BA wearers feel confident about their own air supply

D. Each BA wearer's cylinder pressure/air supply duration, the team's entry time, an agreed maximum duration before mandatory withdrawal regardless of air remaining (to allow safety margin for the exit), and a clear communication and tally system so the bridge/control point always knows who is inside and for how long
