Question 1

The NIOSH Lifting Equation (1994 revision) was designed to be applied in which specific work scenario?

Accepted Answer

Two-handed, symmetrical lifts of objects with good coupling in mild thermal environments

Answer

The 1994 NIOSH Lifting Equation was validated for smooth, two-handed symmetric lifts with good coupling under mild thermal and humidity conditions.

Question 2

A Recommended Weight Limit (RWL) of 20 kg and an actual load of 30 kg yields a Lifting Index (LI) of 1.5. This value indicates:

Accepted Answer

Some workers may be at elevated risk; the task warrants ergonomic redesign

Answer

An LI above 1.0 indicates that the task may pose an elevated injury risk for some workers and ergonomic improvements should be considered.

Question 3

Under OSHA's Recordkeeping Rule (29 CFR 1904), a work-related musculoskeletal disorder requires entry on the OSHA 300 Log when it results in:

Accepted Answer

Days away from work, restricted work, job transfer, medical treatment beyond first aid, or loss of consciousness

Answer

OSHA's recordkeeping criteria require logging injuries or illnesses that result in days away, restricted work, job transfer, medical treatment beyond first aid, or loss of consciousness.

Question 4

Which ergonomics program element is considered the most critical 'gateway' for ensuring that hazards get identified and prioritized for control?

Accepted Answer

Worksite analysis / job hazard identification

Answer

Worksite analysis is the foundational element that identifies and prioritizes ergonomic hazards; without it, training and controls lack direction.

Question 5

In ergonomics program management, the 'hierarchy of controls' places which type of control as most effective for reducing MSD risk?

Accepted Answer

Engineering controls that eliminate or redesign the hazard

Answer

Engineering controls are ranked highest in the hierarchy because they physically eliminate or reduce the hazard at its source rather than relying on behavior.
