What makes a Manual Task Hazardous?

Five Key Risk Factors


One or more of the following 5 risk factors will mean the manual task is hazardous and can cause injury to a worker.

The term hazardous manual task is defined in NSW WHS Regulation 5 as:

a task that requires a person to lift, lower, push, pull, carry or otherwise move, hold or restrain any person, animal or thing that involves 1 or more of the following:

  1. Repetitive or sustained force
  1. High or sudden force
  1. Repetitive movement
  1. Sustained or awkward posture
  1. Exposure to vibration.


Manual Task Injuries to Workers Occur in Two Ways


  1. Gradual wear and tear to joints, ligaments, muscles, and discs between the vertebrae of the spine, caused by repeated or continuous use of the same body parts, including static body positions
  2. Sudden damage caused by strenuous activity, or unexpected movements such as when loads being handled move or change position suddenly.

Injuries can also occur due to a combination of these mechanisms, for example, body tissue that has been weakened by cumulative damage may be vulnerable to sudden injury by lower forces.
