EE drilled a bolt hole to the depth of the 1st drill steel & then joined the 2nd steel to the 1st one. He raised the bolter's boom to meet the lower end of the 2nd steel. He did not have the lower end of the 2nd steel completely engaged in the chuck. As he raised the boom further, the steel sprung laterally striking his right thumb causing a laceration.
