🔍 Key Concepts

• Not gas free means there may still be flammable vapors present in the space • Difference between general 'approval by a person' (Master or OCMI) and formal equipment approval standards for hazardous locations • What 'self-contained, battery fed, explosion-proof' implies for ignition sources in a potentially explosive atmosphere

💭 Think About

• Ask yourself which choice removes dependence on the ship’s personnel and instead relies on standardized, pre‑tested explosion protection for hazardous spaces • Consider whether shore‑side regulatory approval of a specific lamp is the same thing as the lamp itself having an explosion‑proof design suitable for flammable atmospheres • Think about which option would minimize the risk of a spark from wiring, plugs, or ship’s electrical system inside a space that may contain flammable gas

✅ Before You Answer

• Verify which option clearly states the lamp is explosion‑proof as a design feature, not just approved by someone • Check whether the power source is self-contained or connected to the ship’s electrical system • Confirm which option best matches standard practice for entering tanks or spaces that are not gas free and may contain flammable vapors
