You complete a JHA on an employee who stocks shelves at a large home improvement store. The first step of the job is as follows:

The employee manually unloads boxes from the delivery truck. To do this, the employee makes multiple steps as he climbs up into the truck and then backs out, carrying boxes into the store where he or she then climbs up a set of steps before stacking the boxes on the loading dock. The loading dock is cluttered with boxes from the numerous shipments arriving throughout the day. The boxes are smaller, ranging from 6 in. by 6 in. up to 24 in. by 24 in. They weigh 10 to 40 pounds, and they do not have handles.

List the hazards present in this step. Using the risk matrix in the unit lesson, determine the risk level of the task before controls are applied. Using the hierarchy of controls, determine at least two control measures that would reduce the risks present in the task. Explain how the proposed controls would affect severity and likelihood.
