CSO Ergonomics and Manual Handling 2

Question 1

When working at a computer workstation, which of the following describes the recommended ergonomic posture?

Accepted Answer

Back straight, feet flat on the floor, and the monitor top at or slightly below eye level

Answer

A neutral posture — straight back, feet flat, monitor near eye level — minimizes static muscle load and prevents neck and back strain during computer work.

Question 2

Which type of injury is most commonly associated with improper manual handling in the workplace?

Accepted Answer

Back and musculoskeletal injuries

Answer

Improper manual handling — particularly poor lifting technique — is the leading cause of back and musculoskeletal injuries in the workplace.

Question 3

Before attempting to lift a heavy load manually, what is the most important first step?

Accepted Answer

Plan the lift: assess the load weight, clear the travel path, and determine if mechanical aid or assistance is needed

Answer

Planning the lift — assessing weight, clearing the path, and deciding on the right method — prevents injury before the physical work begins.

Question 4

When carrying a load, what is the recommended arm position to minimize strain?

Accepted Answer

Arms close to the body with elbows bent at approximately 90 degrees

Answer

Keeping arms close to the body with elbows bent at 90 degrees maintains a neutral posture and reduces the load's leverage effect on the spine and shoulders.

Question 5

What is a 'team lift'?

Accepted Answer

A coordinated lift performed by two or more workers to safely handle a load too heavy or awkward for one person

Answer

A team lift involves two or more workers sharing a load that exceeds a single person's safe lifting capacity, reducing individual strain and injury risk.
