AEP Workplace Design and Intervention Flashcards

In office ergonomics, the recommended viewing distance from a worker's eyes to the computer monitor is approximately:

Answer: 18–30 inches

A monitor distance of 18–30 inches (arm's length) reduces eye strain while maintaining comfortable neck posture.

What is the primary ergonomic benefit of a split or contoured keyboard design?

Answer: Reduces ulnar deviation and wrist extension

Split keyboards allow each hand to be positioned more naturally, reducing ulnar deviation of the wrists compared to a standard flat keyboard.

For a worker who alternates between sitting and standing, an adjustable-height desk is recommended to transition to standing approximately how often?

Answer: Every 20–30 minutes

Transitioning between sitting and standing every 20–30 minutes helps maintain circulation and reduce static loading on the spine.

An anti-fatigue mat is MOST beneficial for workers who:

Answer: Stand on hard flooring for extended periods

Anti-fatigue mats encourage subtle leg movements and reduce lower limb fatigue for workers who stand on hard surfaces for long durations.

Which anthropometric measurement is MOST relevant when determining the appropriate height of a work surface for a seated operator?

Answer: Elbow height seated

Elbow height seated determines the optimal work surface height to allow the worker to maintain a neutral elbow and shoulder posture.

Which lighting level (in foot-candles) is commonly recommended for general office tasks like reading and writing under OSHA and IES guidelines?

Answer: 30–50 foot-candles

The Illuminating Engineering Society (IES) recommends approximately 30–50 foot-candles for general office task areas.
