Question 1

Which hierarchy of controls is considered the most effective method for reducing ergonomic hazards?

Accepted Answer

Engineering controls (elimination/substitution)

Answer

Engineering controls such as elimination or substitution address the hazard at its source and are the most effective level in the hierarchy of controls.

Question 2

What is 'neutral posture' in ergonomics?

Accepted Answer

Body position where joints are naturally aligned and biomechanical stress is minimized

Answer

Neutral posture refers to natural joint alignment that minimizes stress on muscles, tendons, and joints during work activities.

Question 3

What is the purpose of an early intervention program in occupational injury prevention?

Accepted Answer

To address minor musculoskeletal symptoms before they become serious injuries

Answer

Early intervention programs identify and treat minor symptoms early, preventing progression to disabling injuries and reducing lost workdays.

Question 4

Contact stress in ergonomics refers to:

Accepted Answer

Pressure on soft tissues from hard or sharp surfaces during work

Answer

Contact stress occurs when hard or sharp edges exert pressure on soft tissue areas like wrists or palms, potentially causing nerve and tissue damage.

Question 5

Which workplace intervention best addresses awkward posture as an ergonomic risk factor?

Accepted Answer

Adjusting workstation height and tool design to maintain neutral posture

Answer

Adjusting workstation height and redesigning tools to maintain neutral body posture directly eliminates the biomechanical root cause of awkward posture injuries.
