🔍 Key Concepts

• Storage battery safety requirements on small passenger vessels in 46 CFR (Subchapter T/U) • The properties of electrolyte used in batteries (acid or alkaline and its effect on materials) • Purpose of a battery tray: containment vs. strength vs. fire protection

💭 Think About

• Which choice best addresses the specific hazard created if electrolyte leaks or spills into the tray? • If the tray failed, what kind of damage would the spilled electrolyte most likely cause to nearby structure or equipment? • Which option describes a property that directly protects against chemical attack, not just weight or fire?

✅ Before You Answer

• Verify which option directly relates to resistance to chemical attack from acid/alkaline electrolyte. • Eliminate any option that would allow electrolyte to drain through onto underlying structure. • Distinguish between requirements for mechanical strength or fire resistance and the separate requirement for the tray material itself.
