Question 257Safety & Environmental - Assistant Engineer

The correct answer is D) non-ferrous. When working in areas where explosive gases may accumulate, it is important to use tools that do not create sparks or static electricity, which could ignite the gases. Non-ferrous tools, such as those made of aluminum, brass, or copper, are approved for use in these hazardous environments because they do not produce sparks like high carbon steel tools. The other options are incorrect because high carbon steel tools can create sparks, the Coast Guard does not specifically approve individual tools, and a ferrous cover would not prevent the creation of sparks from the steel tool.
