According to U.S. Coast Guard Regulations (46 CFR Part 92), how many means of escape must be provided in spaces where the crew may be quartered or employed?
• 46 CFR Part 92 requirements for means of escape from accommodation and working spaces • Purpose of having more than one escape route in case one is blocked • Role of watertight doors in emergencies and whether you should rely on them for every escape
• Think about why regulations usually require at least two separate escape paths from spaces where crew live or work. What risk are they trying to reduce? • If a space floods or a fire causes a watertight door to be closed, would it be safe to require all escape routes to pass through watertight doors? • Which option best reflects the idea of having a diverse escape arrangement rather than putting all your eggs in one basket?
• Check 46 CFR Part 92 language about "means of escape" from accommodation spaces—does it mention a minimum of two? • Verify whether the regulation says that at least one escape must avoid reliance on watertight doors, in case those doors are closed in an emergency. • Eliminate any options that would obviously concentrate risk (e.g., all escapes together, all relying on a single type of closure).
