Which on-board document records the timing and sequence of emergency muster actions?

• A. The Muster List
• B. The Garbage Record Book
• C. The Engine Signature Record
• D. The Navigation Lap Book

Answer: (A)

The muster list is used to organize emergencies by specifying who must report and where, and it often includes the timing and sequence of actions during an emergency muster. It sets out crew assignments to muster stations and helps ensure everyone gathers promptly in the correct order, which is exactly what is needed to record the timing and sequence of emergency actions.

Garbage Record Book logs waste disposal in compliance with MARPOL, not emergency muster procedures. The Engine Signature Record pertains to engine-related entries or approvals, not muster sequences. The Navigation Lap Book covers navigation events and watches, not the muster or emergency actions timeline.
