CIEE Ergonomic Intervention & Solutions 4

Question 1

A manufacturing plant wants to reduce awkward bending during floor-level parts retrieval. The best engineering solution is:

Accepted Answer

Install adjustable-height work tables or spring-loaded lift tables

Answer

Adjustable or spring-loaded lift tables bring parts to knuckle height, eliminating bending at the source rather than relying on behavior change.

Question 2

Anti-fatigue mats are recommended for workers who stand on hard floors primarily because they:

Accepted Answer

Reduce static muscle loading in legs and lower back

Answer

Anti-fatigue mats cause subtle postural adjustments that activate calf and leg muscles, reducing static loading and improving circulation.

Question 3

Which scenario represents a successful ergonomic intervention outcome according to the hierarchy of controls?

Accepted Answer

A pneumatic lift eliminates the need to manually carry 50-lb boxes

Answer

A pneumatic lift is an engineering control that eliminates the manual handling hazard, which is higher on the hierarchy than PPE (back belts) or administrative controls (rotation, reminders).

Question 4

A worker repeatedly twists the trunk while transferring boxes between two conveyor lines. The preferred ergonomic fix is:

Accepted Answer

Align both conveyor lines so transfer requires only a straight push

Answer

Realigning conveyor lines to allow a straight transfer eliminates trunk twisting at the source, making it an engineering control.

Question 5

In participatory ergonomics, workers are involved in the intervention process primarily to:

Accepted Answer

Improve accuracy of hazard identification and increase intervention acceptance

Answer

Workers have firsthand knowledge of task demands and are more likely to adopt interventions they helped design, improving both accuracy and buy-in.
