Everyone Has a Body & Does Manual Tasks
Manual tasks may contain risks that:
cause “sudden damage” to a person’s musculoskeletal system, or
create injuries after a period of “gradual wear and tear”.
Those people in our neighbourhood who skateboard from the top of a flight of stairs to the basketball court below come in to the “sudden damage” category. So do other people who play high impact sports such as rugby union, rugby league, AFL and so on.
Most people do not play high impact sports. But many people do manual tasks at work, at home, or at play, that contain risks that create “gradual wear and tear” injuries. These injuries tend to become evident in their later working life and affect their ability to function at work and may affect your workers compensation costs now.
The injury that reveals itself at your workplace today may have been contributed to by the “gradual wear and tear” of doing hazardous manual tasks during out of work hours or in their previous employment.
How do Manual Task Injuries Occur?
The Hazardous Manual Tasks Code of Practice tells us at page 5, that these injuries can occur in two ways:
➢ “gradual wear and tear to joints, ligaments, muscles and inter-vertebral discs
caused by repeated or continuous use of the same body parts, including static
body positions, or
➢ 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 the above mechanisms.”
What Type of Injuries do Worker Experience?
The type of injuries may include;
➢ “sprains and strains of muscles, ligaments and tendons
➢ back injuries, including damage to the muscles, tendons, ligaments, spinal discs,
nerves, joints and bones
➢ joint and bone injuries or degeneration, including injuries to the shoulder, elbow,
wrist, hip, knee, ankle, hands and feet
➢ nerve injuries or compression, for example carpal tunnel syndrome
➢ muscular and vascular disorders as a result of hand–arm vibration
➢ soft tissue injuries including hernias, and
➢ chronic pain.
These injuries are known as musculoskeletal disorders (MSDs). These are the most common workplace injuries across Australia.”
What Manual Tasks Contain Risks?
As explained in the Hazardous Manual Tasks Code of Practice at page 5:
“A hazardous manual task is a task requiring a person to lift, lower, push, pull, carry or otherwise move, hold or restrain any person, animal or thing involving one or more of the following:
➢ repetitive or sustained force
➢ high or sudden force
➢ repetitive movement
➢ sustained or awkward posture, or
➢ exposure to vibration.
These hazards directly stress the body and can lead to an injury.”
Training for Work and Home Manual Tasks
Whatever training you deliver to workers about manual tasks it should also be aimed at workers gaining the reality, understanding, and motivation to eliminate or control the risks of hazardous manual tasks at work and out-of-work.
In order to enhance the reality and understanding of those being trained on manual task risks we recommend that training includes the basics of the musculoskeletal system.
