Manual Handling
Injury Expert Witness
Independent expert opinion on manual handling and lifting injury claims in workers' compensation and public liability proceedings. Risk factor analysis, ergonomic assessment, code of practice compliance and reasonably practicable control evaluation.
Manual Handling Expert Witness Scope
Manual handling injuries are the most common type of workplace injury in Australia. They include injuries from lifting, lowering, pushing, pulling, carrying and otherwise moving objects or people, as well as injuries from sustained awkward postures, repetitive movements and the use of force. These injuries occur across every industry, from warehousing and construction to healthcare and retail.
The expert witness role in manual handling matters is to assess whether the duty holder identified the manual handling risks present in the work, whether the controls implemented were adequate and consistent with the Manual Handling Code of Practice, and whether the training provided to workers was sufficient for the tasks they were required to perform.
Karim Ali provides independent expert opinion on manual handling matters for plaintiff and defendant solicitors and insurers. Instructions are accepted in both workers' compensation and public liability proceedings before courts, tribunals and the Personal Injury Commission.
Common Manual Handling Injury Types
- Spinal and lower back injuries from lifting and carrying loads
- Shoulder, neck and upper limb injuries from overhead work and reaching
- Knee and hip injuries from prolonged kneeling, squatting or awkward postures
- Repetitive strain and overuse injuries from sustained repetitive tasks
- Crush and contact injuries from loss of control of loads being moved
- Patient and resident handling injuries in healthcare and aged care
- Cumulative injuries from years of physically demanding work
Manual handling expert opinions are instructed across warehousing, logistics, construction, healthcare, aged care, retail and manufacturing. Karim has experience across all of these sectors.
Manual Handling Risk Factor Analysis
The Manual Handling Code of Practice identifies specific risk factors that increase the likelihood of injury from manual handling tasks. The expert analysis assesses which risk factors were present in the work, to what degree and whether they were adequately addressed by the duty holder.
The presence of multiple risk factors significantly increases the injury risk. The analysis considers how each factor interacted with the others and whether the combination of factors made the task unreasonably hazardous.
The amount of physical effort required to perform the task, including the weight of the load, the force required to push or pull, and the body weight that must be supported. Tasks requiring excessive force are a primary risk factor for musculoskeletal injury.
The frequency with which a task or movement is repeated over the course of a work period. High repetition combined with force or awkward posture significantly increases injury risk and is a primary cause of cumulative musculoskeletal disorders.
The position of the body during the task, including bending, twisting, reaching and overhead work. Awkward or sustained postures place stress on muscles, tendons, ligaments and joints beyond their comfortable and safe range of motion.
The physical work environment, including space available to perform the task, temperature and humidity, floor surfaces, lighting and the availability and condition of mechanical aids. Adverse environmental conditions increase the risk associated with all other risk factors.
Control Measures Assessed in Manual Handling Matters
The expert analysis assesses whether the controls implemented by the duty holder were adequate and whether higher-order controls were reasonably practicable in the circumstances. Controls are assessed against the hierarchy of controls required under the WHS regulations.
Assessment of whether mechanical aids such as forklifts, pallet jacks, hoists, trolleys and patient lifters were available, suitable for the task and used by workers. Where mechanical aids were not provided, the analysis assesses whether they were reasonably practicable given the nature of the work.
Assessment of whether the task design and workplace layout minimised manual handling risks, including the positioning of storage, the height of work surfaces, the use of gravity to assist movement and the availability of adequate space to perform the task safely.
Assessment of whether team lifts were required for loads that were too heavy, awkward or difficult for a single person, and whether procedures for team lifting were documented, trained and followed. The adequacy of supervision of team lift procedures is also assessed.
Assessment of whether workers received adequate instruction on safe manual handling techniques, including specific training for the tasks they were required to perform. Generic manual handling training is distinguished from task-specific instruction where the nature of the work required it.
Assessment of whether job rotation and rest break arrangements were in place to reduce cumulative exposure to repetitive manual handling. In matters involving repetitive strain or cumulative injury, the work scheduling arrangements are a key element of the adequacy assessment.
Assessment of whether loads were appropriately sized, weighted, packaged and labelled for safe handling, and whether any weight limits were communicated to workers. Load management arrangements are assessed against the requirements of the Manual Handling Code of Practice.
Manual Handling Code of Practice Compliance
The Managing the Risk of Musculoskeletal Disorders at Work Code of Practice (formerly the Manual Tasks Code of Practice) provides detailed guidance on how duty holders should identify, assess and control manual handling risks. The expert analysis assesses whether the duty holder's practices were consistent with the requirements of the code.
The code of practice is admissible in legal proceedings as evidence of what is known about manual handling hazards and the ways of controlling them. Departure from the code is relevant to whether the duty holder acted reasonably.
- Identification of manual handling hazards in the workplace
- Risk assessment methodology applied to manual handling tasks
- Selection and hierarchy of control measures
- Consultation with workers on manual handling risk controls
- Review of controls following incidents or changes to work
- Record keeping requirements for risk assessments and training
Documents Typically Reviewed
The expert opinion is based on a review of all available documents. The following are those most commonly reviewed in manual handling matters.
- Manual handling and musculoskeletal risk assessments for the task
- Safe work method statements covering the relevant work
- Training records and competency assessments for workers
- Incident reports and prior injury records for the task or area
- Workplace inspection records and hazard reports
- Equipment maintenance and inspection records for lifting aids
- Job role descriptions and physical task requirements
- WorkSafe or WHS regulator investigation reports
- Photographs and video of the task or work area
- Medical reports and functional capacity assessments

Does the WHS expert opinion overlap with the medical expert opinion?
The opinions are complementary but address different questions. The medical expert addresses the nature of the injury, its causation in a medical sense and the plaintiff's capacity for work. The WHS expert addresses whether the work was performed safely, whether the duty holder's controls were adequate and whether the work system created a foreseeable risk of the type of injury sustained. Both opinions are typically required in manual handling proceedings.
-
Can the expert give opinion on a cumulative injury claim?
Yes. Cumulative manual handling injuries involve exposure to risk factors over an extended period. The analysis in these matters assesses the work tasks performed over the relevant period, the risk factors present in each task, the adequacy of controls across that period, and whether the cumulative exposure created a foreseeable risk of musculoskeletal injury. These matters often require review of job descriptions, task histories and records spanning several years.
-
Is the analysis different for patient handling in healthcare?
Patient handling matters have some specific characteristics. The load being moved is a person, which introduces unpredictability and limits the degree to which the task can be mechanised. The analysis addresses the duty holder's patient handling procedures, the availability of patient handling equipment, staff training and the adequacy of pre-task patient assessments. Karim has experience in healthcare manual handling matters involving hospitals, aged care facilities and community care settings.
-
Can the worker's technique be addressed in the opinion?
Yes. Where the worker's lifting technique is in issue, the analysis addresses whether the technique used was appropriate and whether the training provided was adequate to produce correct technique in practice. Where a worker was not trained in safe technique or was trained but the training was inadequate for the task, this is relevant to whether any departure from correct technique was itself a consequence of the employer's failure.
