🔍 Key Concepts

• Tank barge compartments may contain flammable vapors unless certified gas-free • Electrical equipment in hazardous locations must be intrinsically safe or explosion-proof to prevent ignition • USCG and OSHA rules distinguish between ordinary flashlights and explosion-proof, certified portable lights

💭 Think About

• Which of these lighting types is specifically designed so it will not ignite flammable vapors if there is a spark or heat inside the lamp? • Is a normal flashlight or just "spark resistant" housing enough protection if flammable gas might be present, or does the entire unit need a tested and certified rating? • On a tank barge that is NOT gas-free, what standard of protection is required for any electrical device you bring into the space?

✅ Before You Answer

• Verify which option clearly states it is explosion-proof and designed for hazardous atmospheres • Check whether the lamp described is self-contained and battery-fed, avoiding external cords that might be damaged or spark • Eliminate any option that sounds like an ordinary flashlight with no specific hazardous-location certification
