An employee was loading a channel (13.5: W X 11" H X 21' 7" L, total of 6,145 lbs.) into the channel cradle of a punch press. The employee entered the channel loading platform, which is used to remove banding and straps, prior to the load being placed. While the employee was guiding the load into position at the machine, the bundle traveled past the backstop and continued toward the employee. The employee was then pinned between the load and the railing of the work platform, suffering fractured vertebrae, a bruised lung, and a rib fracture.
