70% to passWhen required to work in an area where explosive gases may accumulate, you should use hand tools which are _______________.
Anon-ferrous
Bhigh carbon steel
Cfixed with a ferrous cover
Dapproved by the Coast Guard
AI Explanation
The correct answer is A) non-ferrous. When working in an area where explosive gases may accumulate, it is important to use hand tools that do not produce sparks, which could ignite the gases. Non-ferrous tools, such as those made of aluminum or copper, are the safest choice in these environments because they do not create sparks like ferrous (iron-based) tools can. The other answer choices are incorrect because B) high carbon steel tools can still create sparks, C) a ferrous cover does not eliminate the risk of sparks, and D) there is no specific Coast Guard approval required for non-ferrous tools in this context.
