Employee #1, age 20, was removing a portion of the boom of a Lorain 325 25-ton wheel-mounted mobile boom crane. His lead man, the crane operator, was occupied elsewhere. Contrary to his instructions, Employee #1 removed the tip of the crane by taking out the bottom pins first.

He was working alone and of his own will.
