Question

mushroomed ends on chisels must be: * a) painted b) ground off c) ignored d) hammered down

Explanation:

Mushroomed ends on chisels are unsafe (can chip, cause injury). Safety protocols for tools (like chisels in engineering/construction) require grinding off mushroomed ends. Painting, ignoring, or hammering down don't address safety; grinding removes the deformed, unsafe part.

Answer:

B) Ground off
