After a fire is brought under control and apparently extinguished, what does AFF training emphasise about declaring the incident over?

A. Once visible flames are extinguished, the incident can be declared over immediately with no further inspection

B. Re-ignition risk only applies to fires involving flammable liquids, not to other fire types

C. A "fire watch" period and thorough re-inspection (checking for smouldering material, residual heat with thermal imaging if available, and re-ignition risk in concealed spaces such as cable runs or insulation) should be maintained before the incident is formally declared over — re-ignition after an apparently successful knockdown is a real, recurring risk

D. Fire watch periods are an unnecessary precaution that delays the resumption of normal operations without genuine safety benefit

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
