What is the maximum height allowed for downstacking (to shoulder level)?

• A. 6 ft
• B. 5 ft
• C. 7 ft
• D. 8 ft

Answer: (A)

The main idea here is maintaining a safe, ergonomic work height when removing items from a stack. Downstacking to shoulder level should be limited to six feet. Keeping the load at or below six feet puts it within a natural, comfortable reach, reduces the need to bend or lift overhead, and lowers the risk of losing control of the items or injuring yourself. If the stack is higher than six feet, use equipment or break the task into steps so the items stay at shoulder level or below. The other heights either sit below shoulder level or exceed it, which would require overreaching and increase the chance of strain or a drop. Six feet best achieves a safe, practical shoulder-level downstack.
