Question 1

When selecting a power screwdriver for assembly work, which grip style best reduces wrist deviation?

Accepted Answer

Inline (pencil) grip for horizontal surfaces

Answer

An inline grip keeps the wrist in a neutral position when driving fasteners on horizontal surfaces, minimizing ulnar and radial deviation.

Question 2

A worker uses vibrating hand tools for 4 hours daily. Which glove feature MOST reduces risk of hand-arm vibration syndrome (HAVS)?

Accepted Answer

Anti-vibration padding meeting ISO 10819 requirements

Answer

Anti-vibration gloves meeting ISO 10819 are specifically tested and rated to attenuate vibration transmission to the hand and reduce HAVS risk.

Question 3

Which characteristic of scissors makes them most ergonomically appropriate for left-handed users?

Accepted Answer

Offset blade orientation matching left-hand cutting action

Answer

Left-handed scissors have blades offset so the cutting edge faces correctly when held in the left hand, preventing the wrist twist that causes strain.

Question 4

A warehouse team must move pallets weighing up to 500 lbs. Which powered equipment selection criterion is MOST important from an ergonomic standpoint?

Accepted Answer

Operator posture and visibility while driving

Answer

Operator posture and sightlines directly affect musculoskeletal loading and fatigue during prolonged powered equipment use.

Question 5

For repetitive pinch-grip tasks on a production line, which tool handle modification would MOST reduce pinch force requirements?

Accepted Answer

Increasing handle diameter to allow a power grip

Answer

A larger handle diameter converts a high-force pinch grip into a lower-force power grip, significantly reducing fingertip and thumb forces.
