Manual handling hazards are one of the leading causes of workplace injuries in Australia, contributing to musculoskeletal disorders (MSDs), fatigue, and long-term health risks. From lifting and pushing to repetitive movements and awkward postures, these everyday tasks can quickly become hazardous when done unsafely.

Understanding the different types of manual handling hazards is essential for employers, workers, and WHS managers who want to prevent injuries, comply with safety legislation, and build healthier workplaces. Identifying risks early and applying practical controls can reduce injury rates, improve productivity, and support long-term worker wellbeing.

What Are Manual Handling Hazards?

Manual handling hazards refer to workplace activities that involve lifting, carrying, pushing, pulling, holding, or restraining objects, people, or animals. These tasks may seem routine, but when they involve repetitive strain, excessive force, or poor technique, they can cause serious injuries such as sprains, strains, fractures, and long-term musculoskeletal disorders (WMSDs).

 

In Australia, hazardous manual tasks are recognised under workplace health and safety (WHS) laws because of their high risk for injury. Employers have a legal duty to identify, assess, and control these hazards to keep workers safe. Workers also have a responsibility to follow safe practices and report risks when they arise.

 

Understanding the different types of manual handling risks and how they occur can help organisations implement targeted injury prevention strategies. Proactively addressing these hazards reduces claims, downtime, and healthcare costs while promoting a safer, healthier workplace.

Categories of Manual Handling Hazards in the Workplace

Not all manual handling tasks carry the same level of risk. Workplace health and safety (WHS) guidelines highlight specific hazard categories that contribute most to injuries. These risks should be identified early, allowing employers to take proactive measures such as implementing structured manual handling training. Doing so helps lower injury rates and contributes to a safer, more efficient workplace.

Repetitive Movement Hazards

Repetitive tasks, such as constant lifting, bending, or twisting, place stress on the same muscle groups and joints. Over time, this can result in cumulative strain injuries and long-term musculoskeletal disorders. In fact, repetitive strain is one of the most common workplace injuries in Australia, often linked to unsafe manual handling techniques.

So, what type of hazard is repetitive movement?

It is classified as a repetitive movement hazard, a specific kind of manual handling hazard that arises when workers perform the same actions repeatedly without adequate breaks or ergonomic support. 

 

Common examples include packing boxes on a production line, repetitive scanning at checkouts, or continuous data entry with poor ergonomics. These tasks highlight how repetitive movement becomes hazardous when the body is subjected to ongoing strain, especially in environments where safe handling practices are not followed.

Sustained & Sudden Force Hazards

Applying sustained force, such as holding a heavy item for an extended period, or sudden force, like catching a falling object, can put significant strain on muscles, tendons, and ligaments. These types of physical exertion often result in acute injuries, including sprains, strains, or even fractures.

In the context of workplace safety, what is a sustained force in manual handling?

It refers to the continuous physical effort required to grip, carry, or support a load without taking breaks. This kind of prolonged exertion becomes especially hazardous when dealing with heavy or awkward items. When sustained force is combined with the sudden force injury risk of unexpected movements, the likelihood of harm increases significantly.

 

Practical examples include holding tools overhead for extended periods, suddenly pulling jammed equipment, or pushing a heavy trolley up an incline. Each of these scenarios demonstrates how both sustained and sudden forces can quickly escalate into serious manual handling hazards if not properly managed.

Awkward Posture Hazards

When workers operate in awkward or sustained postures, such as bending, twisting, reaching, or working above shoulder height, the spine and joints experience unnatural strain. Prolonged exposure increases the likelihood of chronic back pain, shoulder injuries, and neck disorders, making awkward posture hazards one of the most common causes of long-term musculoskeletal issues.

Why are repetitive movements and awkward postures considered high risk?

Both expose the body to continuous stress without proper recovery time, leading to fatigue, cumulative strain, and eventual injury. Awkward postures also make it harder for muscles and joints to function efficiently, which accelerates the damage caused by repetitive tasks. Implementing effective awkward posture control measures, such as ergonomic workstation design, use of adjustable equipment, or rotating job tasks, helps reduce these risks significantly.

 

Common examples include stocking shelves at high or low levels, working in confined spaces, or prolonged crouching on construction sites, all of which highlight how posture-related hazards contribute to workplace injuries if left unmanaged.

Whole-Body & Hand-Arm Vibration Hazards

Exposure to vibration from power tools, machinery, or vehicles can cause serious long-term health issues if not properly managed. Whole-body vibration hazards typically come from operating equipment like forklifts or heavy vehicles, placing strain on the spine and increasing the risk of chronic back pain. Hand-arm vibration hazards, on the other hand, result from using tools such as jackhammers or handheld drills, which can damage circulation, grip strength, and nerve function.

How can we distinguish the difference between whole-body and hand-arm vibration hazards?

The key distinction lies in how the vibration enters the body. Whole-body vibration spreads through the seat or platform and mainly affects the spine, while hand-arm vibration is transmitted directly through handheld tools and impacts the arms, hands, and fingers. 

 

Examples include forklift drivers exposed to vehicle vibrations and construction workers using jackhammers or drills for extended periods. Without proper controls, both forms of vibration can lead to irreversible health conditions, making early prevention critical.

Ergonomic Risk Factors in Manual Handling

Injuries in manual handling aren’t always the result of heavy loads. Many stem from ergonomic risk factors in manual handling that place unnecessary stress on the body. Poor workplace design, unsuitable tools, and tasks that force the body into unsafe positions all contribute to workplace ergonomic hazards and increase the likelihood of work-related musculoskeletal disorders (WMSDs).

What are the ergonomic risk factors for manual handling?

Some key ergonomic risk factors in manual handling include:

 

  • Repetitive or sustained actions (lifting, pushing, or pulling without recovery time).
  • Awkward working heights or layouts that force workers to bend, twist, or reach excessively.
  • Inappropriate tools or equipment that require extra force or poor grip.
  • Workplace design flaws, such as narrow spaces, poor seating, or unadjustable desks.

 

These are the most significant WMSD ergonomics risks that tend to cause chronic injuries if unmanaged.

Addressing ergonomic hazards requires more than quick fixes. It involves structured ergonomic assessments, redesigning workstations, introducing adjustable equipment, and rotating tasks to balance physical strain. Workplaces that invest in strong ergonomic practices not only reduce injury rates and compensation claims but also improve productivity, employee morale, and long-term safety outcomes.

Risk Assessment and Control Measures

To create safer workplaces, employers must move beyond raising awareness and take proactive steps by conducting structured risk assessments for hazardous manual tasks. A manual handling risk assessment involves identifying the task, evaluating the associated risks, and implementing practical control measures to reduce the chance of injury.

 

A strong risk assessment looks at:

  • The nature of the task – frequency, duration, and intensity.
  • The load being handled – weight, stability, or awkward shape.
  • The working environment – space, lighting, flooring, and temperature.
  • The worker – their physical capacity, skills, and training.

How can employers create safer workplaces for hazardous manual tasks?

The answer lies in carrying out thorough risk assessments and applying the hierarchy of controls. According to WorkSafe guidelines on hazardous manual handling, controls should follow the hierarchy of risk management:

 

  1. Elimination: Remove the hazardous task entirely if possible.
  2. Substitution: Replace manual processes with safer alternatives (e.g., using lifting devices).
  3. Engineering controls: Redesign workstations, provide adjustable tools, or improve ergonomics.
  4. Administrative controls: Rotate tasks, limit exposure time, and provide manual handling training.
  5. Personal protective equipment (PPE): Gloves, supportive braces, or vibration-dampening gear where applicable.

Employers also have a legal responsibility under WHS legislation to conduct these assessments and ensure ongoing compliance. Failure to do so can increase injury risks, compensation claims, and lost productivity.

 

At AusRehab, we help businesses carry out comprehensive workplace assessments to spot risks, ensure suitable duties align with workers’ capacity, and recommend workplace adjustments where needed to support long-term health, compliance, and a safe return to work for injured workers.

Prevention Strategies & Injury Reduction

Applying Workplace Injury Prevention Strategies

 

Workers can lower injury risks by adopting injury prevention strategies in the workplace, such as using lifting aids, trolleys, or adjustable equipment. Rotating between tasks, redesigning workstations to reduce awkward reaches, and taking regular breaks all help minimise repetitive strain and fatigue.

 

Building a Safety-Focused Culture

 

A workplace that encourages open reporting, regular toolbox talks, and visible leadership commitment makes it easier for workers to practise safe habits daily. This culture ensures that safe manual handling techniques are reinforced consistently.

 

Using Ergonomics to Identify Risks

Practical ergonomic assessments help employers identify subtle risk factors, such as desk height, repetitive mouse use, or vibration exposure. Adjustments as simple as new seating, anti-fatigue mats, or ergonomic tools can drastically cut injury rates.
