Question 1

What is the purpose of a manual handling risk assessment?

Accepted Answer

To identify hazardous operations and determine what control measures are needed to reduce injury risk

Answer

A manual handling risk assessment identifies all potentially hazardous manual handling operations, assesses the risks using the TILE framework, and determines what control measures are needed to reduce the risk of injury as far as reasonably practicable.

Question 2

How does 'load instability' increase manual handling risk?

Accepted Answer

An unstable load may shift unexpectedly, causing the worker to make sudden compensating movements that increase injury risk

Answer

An unstable load (such as a container with liquid, a bundle of loose materials or a load with an unknown centre of gravity) can shift during handling, causing the worker to make sudden, uncontrolled movements to compensate, increasing the risk of muscle strain and loss of control.

Question 3

What is 'stooped working posture' and why is it a risk factor for back injury?

Accepted Answer

Working with the spine bent forward; it places excessive compressive and shear forces on the lumbar discs

Answer

Stooped posture (bending forward at the waist) places the lumbar spine under significantly increased compressive and shear forces. Prolonged or repeated stooped posture, especially with manual handling, greatly increases the risk of disc damage and lower back pain.

Question 4

What is the effect of frequent twisting during lifting operations?

Accepted Answer

Twisting combines bending and rotation forces on the spine, significantly increasing the risk of disc and muscle injury

Answer

Twisting while lifting combines compressive forces from the load with rotational forces on the intervertebral discs and supporting muscles. This combination significantly increases injury risk, especially to the lumbar spine.

Question 5

What does the 'L' in TILE stand for in manual handling risk assessment?

Accepted Answer

Load

Answer

The 'L' in TILE stands for Load — the characteristics of the object being moved, including its weight, size, shape, centre of gravity, stability and whether it has handles. Load characteristics significantly affect manual handling risk.
