Which type of portable lighting may be used to enter a compartment on a tank barge which is NOT gas-free?
AI Explanation
The correct answer is C) An explosion-proof, self-contained, battery-fed lamp.
This is the correct answer because the regulations require the use of explosion-proof lighting when entering a compartment on a tank barge that is not gas-free. Ordinary flashlights or lamps that are not specifically designed for hazardous environments could produce a spark or flame, which could ignite any flammable vapors present in the compartment. An explosion-proof lamp is designed to contain any internal sparks or heat, preventing them from igniting the surrounding atmosphere.
The other options, such as a standard three-cell flashlight (A) or a spark-resistant lamp (B), would not meet the safety requirements for this situation and could potentially cause an explosion.
