CIEE Ergonomic Intervention & Solutions 2

Question 1

A warehouse worker reports wrist pain from repetitive scanning. Which engineering control should be prioritized first?

Accepted Answer

Reposition the scanner to reduce wrist deviation

Answer

Engineering controls that eliminate or reduce the hazard at the source are the preferred hierarchy-of-controls solution over PPE or administrative measures.

Question 2

Which type of intervention directly modifies the physical work environment to reduce ergonomic risk?

Accepted Answer

Workstation redesign

Answer

Workstation redesign is an engineering control that physically modifies the environment, unlike administrative controls such as rotation or training.

Question 3

An assembly line requires workers to reach overhead for 60% of their cycle. What is the most effective ergonomic solution?

Accepted Answer

Lower the work surface or use a lift assist device

Answer

Repositioning the work within the power zone (between hip and shoulder height) via engineering controls eliminates the overhead-reach hazard.

Question 4

When evaluating a proposed ergonomic intervention, which metric most directly measures its effectiveness?

Accepted Answer

Reduction in musculoskeletal disorder (MSD) incident rate

Answer

A reduction in MSD incident rate directly demonstrates that the intervention has lowered injury risk, which is the primary goal.

Question 5

A sit-stand workstation intervention is most effective when:

Accepted Answer

Workers alternate positions roughly every 30–60 minutes

Answer

Research supports position changes every 30–60 minutes to prevent static loading from both prolonged sitting and standing.
