The company wishes to store heavier boxes on this overhead shelf which means a reach above the shoulder would be in the danger zone for lifting.
A) How high does the platform (or a step stool) need to be for your worker to reach a box on a 180cm high shelf with hands at shoulder height as shown in the right figure? Explain. State any assumptions you make (e.g., does the worker wear safety shoes?).
B) Per OSHA 1926.1053, how many steps does your step stool need for your worker - including the step (platform) they stand on? Explain. State any assumptions you make.
C) For your worker do you recommend a platform or step stool for this task?
Do your calculations for an above average (84th %) male.
