Is push-to-start activation feasible? If not, refer to MEEG for trigger guidelines.

Is the tool in question designed such that the transmission of vibration is minimized (i.e. vibration not noticeably transmitted to the hand)?

Is an overhead balancer needed? Use when tool is greater than 6 lbs. (3 kg.) or if multiple tools are used at the workstation.

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.)
