Light Work, <= 10 lbs. (5 kg)
Precision Work, < 2 lbs. (1kg)
Heavy Work, > 10 lbs. (5 kg)
Measured from standing surface to where the work is performed (hand height).
Line of Sight Obstructions Is it possible to see the fixture or perform task without having to stoop or bend?

Circle item(s) that fall outside design-in guidelines: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
For each item circled, indicate by writing on page 6 either…a. Why it is acceptable to have that particular item outside of the guidelines. ORb. What the plan is to make the item fall within the design-in guidelines.
Is the equipment or process design ergonomically acceptable? Yes No (If “No” detail corrective action on page 6.)
Note: The above analysis is based on People Focus Practice sheets dated: _______________________
