A rig was being rigged down and four employees were unhooking the mudline to stack out for transport. Two employees were working on the ground and two were on the mudtank walkway. One of the employees on the walkway leaned out against the handrail to help lift the hose from the two employees on the ground. As the employee leaned out, the handrail gave way and the employee fell about 10 feet (3 meters) to the ground. One of the employees on the ground was able to break his fall. Fortunately, his only injury was a small fracture to the top of his foot when he struck a hose stand.
