Manual Handling
Musculoskeletal injuries from manual handling are the most common workplace injuries in construction. This section covers correct lifting techniques, team lifting procedures, mechanical aids (trolleys, hoists, forklifts), hazardous manual task risk factors (repetition, sustained postures, high force), and ergonomic principles for construction work.

Review these sample questions before starting the practice test.
Q1: What is manual handling?
- A. Any activity requiring a person to use physical force to lift, push, pull, carry, or hold an object or person β
- B. Using a manual (handbook) on site
- C. Only lifting heavy objects
- D. Operating hand tools
Manual handling includes any activity involving physical force to lift, lower, push, pull, carry, move, hold, or restrain something, including repetitive tasks and sustained postures.
Q2: What is the recommended maximum weight for one person to lift?
- A. There is no fixed limit β assess each task based on risk factors β
- B. 50 kg
- C. 100 kg
- D. 10 kg
There is no single fixed weight limit. The safe lifting capacity depends on multiple factors including the load, posture, frequency, distance, grip, and individual capability.
Q3: What is the correct lifting technique?
- A. Bend your back and keep legs straight
- B. It does not matter as long as the load is light
- C. Lift quickly with a jerking motion
- D. Bend your knees, keep back straight, hold load close to body, avoid twisting β
Correct lifting technique involves bending the knees, keeping the back straight, holding the load close to the body, using leg muscles, and avoiding twisting movements.
Q4: What risk factors increase the chance of manual handling injuries?
- A. Working outdoors
- B. Repetitive movements, awkward postures, heavy loads, vibration, and sustained force β
- C. Working alone
- D. Using new tools
Key risk factors for manual handling injuries include repetitive movements, awkward or sustained postures, heavy or bulky loads, vibration, rapid or sudden force, and poor environmental conditions.
Q5: What type of injury is most commonly associated with poor manual handling?
- A. Musculoskeletal disorders (MSDs) such as back injuries, strains, and sprains β
- B. Hearing loss
- C. Chemical burns
- D. Sunburn
Musculoskeletal disorders (MSDs) are the most common injuries from poor manual handling, particularly lower back injuries, shoulder strains, and repetitive strain injuries.
Q6: Before lifting a load, what should you assess?
- A. The colour of the load
- B. Only whether you feel strong enough
- C. The weight, size, shape, grip, distance to carry, and whether mechanical aids are available β
- D. Nothing β just lift it
Before lifting, assess the weight, size, shape, grip points, carrying distance, pathway obstacles, and whether mechanical aids (trolleys, forklifts) could be used instead.
Q7: What is a mechanical aid in the context of manual handling?
- A. A first aid kit
- B. A construction helmet
- C. A safety sign
- D. Equipment such as trolleys, forklifts, hoists, or conveyors that reduce physical effort β
Mechanical aids include trolleys, hand trucks, forklifts, hoists, conveyors, and pallet jacks β equipment that reduces or eliminates the need for manual lifting.
Q8: When team lifting, what is the most important factor?
- A. All team members wearing the same colour hi-vis
- B. Clear communication, coordinated movements, and a designated leader to call the lift β
- C. Having at least 10 people
- D. The strongest person lifts the heaviest end
Team lifting requires clear communication with a designated person to coordinate the lift (calling "lift on three"), and all members must move together in a coordinated manner.
