Question 1

What is the guideline maximum weight for a woman lifting close to the body at waist height according to HSE filter figures?

Accepted Answer

16 kg

Answer

The HSE guideline filter figures suggest a maximum of approximately 16 kg for a woman lifting close to the body at elbow/waist height. This compares to 25 kg for men in the same position. These are not absolute limits but trigger points for detailed assessment.

Question 2

Which of the following is a health effect commonly associated with prolonged DSE use without adequate breaks?

Accepted Answer

Temporary eye strain and visual fatigue

Answer

Prolonged DSE use without adequate breaks commonly causes temporary eye strain (asthenopia), visual fatigue, headaches, and dry eyes. While these are usually temporary and resolve with rest, they can significantly affect comfort and productivity. Upper limb disorders and back pain are also associated risks.

Question 3

In manual handling, what does 'kinetic lifting technique' involve?

Accepted Answer

Keeping the back straight, bending the knees, keeping the load close, and using leg muscles to lift

Answer

The kinetic lifting technique involves maintaining a straight back, bending at the knees, keeping the load close to the body, and using the strong leg muscles rather than the weaker back muscles to power the lift. This reduces compressive forces on the lumbar spine.

Question 4

What type of risk assessment is specifically required by Regulation 4 of the Manual Handling Operations Regulations 1992?

Accepted Answer

A specific manual handling assessment considering task, load, working environment and individual capability

Answer

Regulation 4 requires a specific manual handling risk assessment that considers the task, the load, the working environment, and individual capability (the TILE factors). This is distinct from a general workplace risk assessment under the Management Regulations.

Question 5

Which of the following is an example of a secondary preventive measure for musculoskeletal disorders?

Accepted Answer

Health surveillance to detect early symptoms before they become serious

Answer

Health surveillance is a secondary prevention measure — it aims to detect early signs of musculoskeletal disorders before they develop into serious conditions. Primary prevention eliminates or reduces the hazard, while tertiary prevention involves rehabilitation after injury has occurred.
