CEAS Ergonomic Interventions & Solutions Flashcards

When should a CEAS specialist recommend a footrest for a seated workstation?

Answer: When the chair cannot be lowered enough for the worker's feet to rest flat on the floor

A footrest is indicated when the chair must be raised to achieve proper elbow height, leaving the worker's feet dangling without floor contact.

Which lighting adjustment is most effective at reducing digital eye strain at computer workstations?

Answer: Position the monitor perpendicular to windows and use indirect or diffused overhead lighting

Orienting the monitor perpendicular to windows eliminates direct glare and veiling reflections, while diffused lighting reduces harsh contrast between the screen and surroundings.

A CEAS specialist recommends voice recognition software to reduce keyboard use for a worker with carpal tunnel syndrome. This is an example of which type of ergonomic control?

Answer: Engineering control (technology substitution)

Replacing keyboard input with voice recognition is a technology-based engineering control that physically reduces repetitive hand and wrist exposure.

What is the ergonomic benefit of a negative-tilt keyboard tray?

Answer: Promotes neutral or slightly extended wrist posture by angling the keys away from the user

A negative tilt (front of keyboard higher than the back) encourages a neutral or slightly extended wrist position, reducing flexion and carpal tunnel pressure.

Which type of ergonomic intervention targets repetitive motion injury risk through product redesign?

Answer: Engineering control via tool or equipment redesign

Redesigning tools or equipment to better fit the task and the worker is an engineering control that directly reduces biomechanical exposure at the source.

After implementing ergonomic interventions at a workstation, what is the most important follow-up action for a CEAS specialist?

Answer: Conduct a post-intervention assessment to verify effectiveness and worker acceptance

Post-intervention follow-up confirms that changes reduced risk factors, verifies correct use by the worker, and identifies any remaining or new concerns.
