Question 1

What is the recommended approach when pushing or pulling a load?

Accepted Answer

Push rather than pull where possible, keep the force at waist height, and maintain good footing

Answer

Pushing is generally safer than pulling because you can use your body weight to help and maintain better posture. Force should be applied at waist height, and good footing is essential to avoid slipping.

Question 2

What mechanical aid can reduce manual handling risk for moving loads across a flat surface?

Accepted Answer

A trolley, pallet jack, or hand truck

Answer

Trolleys, pallet jacks, and hand trucks are mechanical aids that significantly reduce the physical effort required to move loads across flat surfaces, reducing the risk of manual handling injuries.

Question 3

What is 'kinetic lifting' technique?

Accepted Answer

A lifting method that uses momentum and proper body mechanics to reduce strain during repetitive lifting tasks

Answer

Kinetic lifting uses the body's natural momentum and proper posture to reduce strain, particularly useful in repetitive lifting tasks. It emphasises smooth, continuous movement rather than static lifting.

Question 4

What environmental factor can increase manual handling risk on a NZ construction site?

Accepted Answer

Wet or uneven ground surfaces that affect footing and balance

Answer

Wet, muddy, or uneven ground affects a worker's stability and balance during manual handling, increasing the risk of slips, trips, and loss of control of the load.

Question 5

Why is twisting while lifting particularly dangerous?

Accepted Answer

Because it places the spine under combined loading — compression plus rotation — which greatly increases injury risk

Answer

Twisting while lifting combines compressive and rotational forces on the spine, greatly increasing the risk of disc injuries. Workers should move their feet to turn rather than twisting at the waist.
