USCG Exam PracticeElectrical safety and general safety
Electrical equipment installed in a paint locker aboard a vessel must be which of the following?
- A. Waterproof and double-insulated
- ✓ Explosion-proof or intrinsically safeCorrect
- C. Grounded to the hull and fused at reduced amperage
- D. Rated for marine use and enclosed in a metallic housing
Why B is correct
46 CFR §183.530(b) requires that electrical equipment in lockers used to store paint, oil, turpentine, or other flammable liquids must be explosion-proof or be part of an intrinsically safe system. Waterproofing and grounding alone do not satisfy this hazardous-area requirement.
