🔍 Key Concepts

• 46 CFR requirements for fire protection on tank vessels • Purpose and placement of low-velocity water spray systems on weather decks • Difference between number of systems/zones and number of hand applicators/nozzles

💭 Think About

• Think about why low-velocity spray is used on the weather decks of tankships—what are these sprays trying to protect or cool in case of fire? • Consider whether the regulation talks about a single fixed system or individual applicators positioned in different locations. • Ask yourself if redundancy and coverage on a large tankship would likely require more than one applicator, and how many would be reasonable to ensure full deck coverage.

✅ Before You Answer

• Verify the exact wording in 46 CFR Part 34 or 32 (Fire protection for tank vessels) regarding "low-velocity spray applicators." • Check if the requirement is stated as a minimum number of applicators on weather decks, not just total nozzles in the system. • Confirm you are looking at the section for tankships carrying flammable/combustible liquids in bulk, not for other vessel types.
