EE STRUCK HIS HEAD ON A PIECE OF ANGLE IRON WHICH WAS WELDED ON BOTTOM OF DRAGLINE HOUSING. BRACKET USED TO HOLD AN OLD TELEPHONE BOX FOR GROUND CAB COMMUNICATION, THAT HAD BEEN REMOVED. THE TWO ANGLE IRON BRACES WERE LEFT EXTENDING APPROX. 1'EACH. THIS IS AN AREA WHERE HARD HATS SHOULD ALWAYS BE WORN.
