Question 43Gas Turbine - Assistant Engineer

The correct answer is B) Nickel. Wrenches used on gas turbine engines should be plated with nickel to prevent sparking, which could ignite the flammable fuel vapors present in the engine compartment. Nickel is a non-sparking material that helps reduce the risk of explosions or fires when working on sensitive gas turbine equipment. The other answer choices, such as bronze, carbon, or silver, do not have the same non-sparking properties required for safe use on gas turbine engines.
