🔍 Key Concepts

• 46 CFR Part 35 requirements for firefighting equipment on inspected vessels • Specific section in 46 CFR 35 that covers self-contained breathing apparatus (SCBA) • Typical service time ratings for pressure-demand, open circuit SCBAs used in marine firefighting

💭 Think About

• Which of these time durations is most commonly associated with standard marine firefighting SCBA units? • How would the required minimum air supply relate to the time needed to safely enter, work in, and exit a hazardous atmosphere on board? • Does Coast Guard regulation usually set a high, medium, or low minimum standard for firefighter protection time?

✅ Before You Answer

• Locate the exact subsection in 46 CFR Part 35 that mentions SCBA requirements and read the full sentence carefully • Confirm that the regulation specifies pressure-demand, open circuit and not another type of respirator • Verify that the time given is described as a minimum air supply in minutes, not a range or optional recommendation
