70% to pass

When required to work in an area where explosive gases may accumulate, you should use hand tools which are _______________.

Aapproved by the Coast Guard
Bnon-ferrous
Chigh carbon steel
Dfixed with a ferrous cover
AI Explanation

The correct answer is B) non-ferrous. When working in areas where explosive gases may accumulate, it is crucial to use hand tools that do not produce sparks or static electricity, which could ignite the gases. Non-ferrous tools, such as those made of aluminum, brass, or bronze, are the appropriate choice in these hazardous environments. They do not create the same risk of ignition as ferrous (iron-based) tools, which can produce sparks. The other answer choices are incorrect because: A) the Coast Guard does not specifically approve individual hand tools for this purpose; C) high carbon steel tools can still produce sparks; and D) a ferrous cover does not eliminate the risk of spark generation.
