🔍 Key Concepts

• 46 CFR Subchapter T requirements for machinery and electrical installations on small passenger vessels • Purpose of battery trays and enclosures on vessels, especially regarding electrolyte (acid) spills • Difference between ventilation requirements and structural/containment requirements for batteries

💭 Think About

• Which option directly addresses protection against damage from battery acid or electrolyte, rather than location convenience or security? • Look at which choices might actually create additional hazards, such as trapped explosive gases or exposure to bilge water. • Think about what the regulation is most concerned with: preventing corrosion, short circuits, and fire from spilled electrolyte— which choice targets that concern most clearly?

✅ Before You Answer

• Verify in 46 CFR Subchapter T how storage batteries must be installed and supported, especially language about trays or other suitable supports. • Check whether the rules ever recommend placing batteries near the bilge or in locked, poorly ventilated spaces—would that align with good safety practice? • Confirm that the requirement focuses on containment and protection from electrolyte damage, not on being visible from the engines or improving vessel stability.
