🔍 Key Concepts

• 46 CFR requirements for fire main and fire hydrant coverage on inspected vessels • Purpose of having multiple fire hose streams available in any accessible space • Difference between pressure requirements and coverage/stream requirements in fire main design

💭 Think About

• Ask yourself what the regulation is trying to guarantee about how many hoses can fight a fire in the same space at the same time. • Consider whether the rule is focused on the type of nozzle/stream, the pressure at the nozzle, or the number of effective streams available. • Think about how fire teams typically attack a fire on board: do they usually rely on a single hose line or more than one?

✅ Before You Answer

• Verify in 46 CFR that the requirement speaks about coverage of each accessible space and what exactly must be able to reach it. • Check whether the phrase used in the regulation mentions number of streams or pressure values (psi). • Confirm whether the wording refers to separate outlets or only to the capability of one hydrant.
