🔍 Key Concepts

• 46 CFR Subchapter D requirements for tank vessels carrying oil or hazardous liquids • Location and purpose of low-velocity water spray (water-fog) applicators on tankships • Relationship between shipboard fire hose stations and additional portable firefighting equipment

💭 Think About

• Think about why water-fog applicators are required on tankships in the first place. What specific fire hazards are they meant to address? • Consider whether the number required would be closer to the number of hose stations or a smaller set of specialized tools placed in key areas. • Ask yourself if every part of the cargo area and pumproom must be reachable with these applicators, and how that affects the total number needed.

✅ Before You Answer

• Look up the exact CFR citation that lists the minimum number of low-velocity water spray applicators for tankships (verify in 46 CFR fire protection requirements). • Confirm whether the requirement is a fixed number per vessel or based on vessel length or hose stations. • Verify that you are not confusing foam applicators or portable foam equipment with water-fog applicators—these have separate requirements.
