When selecting a power screwdriver for assembly work, which grip style best reduces wrist deviation?
Answer: Inline (pencil) grip for horizontal surfaces
An inline grip keeps the wrist in a neutral position when driving fasteners on horizontal surfaces, minimizing ulnar and radial deviation.
A worker uses vibrating hand tools for 4 hours daily. Which glove feature MOST reduces risk of hand-arm vibration syndrome (HAVS)?
Answer: Anti-vibration padding meeting ISO 10819 requirements
Anti-vibration gloves meeting ISO 10819 are specifically tested and rated to attenuate vibration transmission to the hand and reduce HAVS risk.
Which characteristic of scissors makes them most ergonomically appropriate for left-handed users?
Answer: Offset blade orientation matching left-hand cutting action
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.
A warehouse team must move pallets weighing up to 500 lbs. Which powered equipment selection criterion is MOST important from an ergonomic standpoint?
Answer: Operator posture and visibility while driving
Operator posture and sightlines directly affect musculoskeletal loading and fatigue during prolonged powered equipment use.
For repetitive pinch-grip tasks on a production line, which tool handle modification would MOST reduce pinch force requirements?
Answer: Increasing handle diameter to allow a power grip
A larger handle diameter converts a high-force pinch grip into a lower-force power grip, significantly reducing fingertip and thumb forces.
Which feature of an ergonomic stapler most directly reduces peak hand force during stapling?
Answer: Extended lever arm that distributes force over a wider range of motion
A longer lever arm increases mechanical advantage, spreading the required force over a greater distance and reducing peak force exerted by the user.
When evaluating pliers for electrical maintenance work, which factor is MOST relevant to reducing contact stress?
Answer: Insulated handles with a diameter between 1.25 and 2 inches
Handles in the 1.25–2 inch diameter range with insulation cushion pressure points on palm and fingers while also providing electrical protection.
