Question 1

What is the significance of 'cumulative loading' in manual handling?

Accepted Answer

Repeated handling of loads throughout a shift can accumulate stress on the body, increasing injury risk even if each individual lift is within guidelines

Answer

Cumulative loading refers to the total physical stress imposed on the body by repeated handling operations throughout a shift or over time. Even loads within guideline weights can cause injury if handled repeatedly, as the body has insufficient recovery time.

Question 2

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

Accepted Answer

Individual

Answer

The 'I' in TILE stands for Individual — the characteristics of the worker undertaking the task, including their physical capability, health status, pregnancy, fitness level and any previous musculoskeletal conditions that may increase their risk.

Question 3

Which construction task commonly causes hand-arm vibration syndrome (HAVS)?

Accepted Answer

Using vibrating tools such as breakers, grinders and compactors

Accepted Answer

Tingling and numbness in the fingers, especially after using vibrating tools

Answer

Early symptoms of HAVS include tingling and numbness in the fingers (often more noticeable after using vibrating tools or in cold conditions), followed later by blanching (whitening) of the fingers, known as vibration white finger.

Question 5

What is the Exposure Action Value (EAV) for hand-arm vibration under the Control of Vibration at Work Regulations 2005?
