Falls from Height
Expert Witness
Expert opinion on falls from height incidents in Australian courts and tribunals. Scaffold collapses, ladder falls, roof access, open edges and mezzanine falls. Hierarchy of controls assessment, fall protection adequacy review and code of practice compliance.
Falls from Height Expert Witness Scope
Falls from height are the leading cause of fatalities in Australian workplaces. They occur across construction, maintenance, warehousing, telecommunications and other industries where workers access elevated areas. The severity of these incidents and the high standard of care required by law make them among the most frequently litigated categories of workplace injury.
The expert witness role in falls from height matters is to assess whether the duty holder applied the hierarchy of controls for work at height, whether the fall protection measures in place were adequate, whether the training and competency requirements were met and whether the applicable code of practice and regulations were followed.
Karim Ali provides independent expert opinion on falls from height matters for plaintiff and defendant solicitors and insurers, in both workers' compensation and public liability proceedings. As head of occupational safety at Origin Energy, Karim has direct operational experience managing working at height risks in complex industrial environments.
Key Issues in Falls from Height Claims
- Whether the risk of a fall was reasonably foreseeable in the circumstances
- Whether the duty holder applied the hierarchy of controls for work at height
- Whether fall prevention systems were installed and adequate for the work
- Whether fall arrest equipment was provided, fitted and maintained correctly
- Whether workers were trained and assessed as competent for working at height
- Whether the Safe Work Method Statement for the task was adequate
- Whether scaffolding was erected and inspected in accordance with the regulations
- Whether the construction-specific working at height duties were met
Falls from height matters frequently involve a site inspection to assess the physical conditions at the incident location. Expert opinion is delivered as an expert witness report compliant with the applicable court code of conduct.
Common Fall from Height Scenarios
Falls from height occur in a wide range of workplace settings and involve a variety of access methods and elevated work areas. The following scenarios are those most commonly instructed in expert witness proceedings.
-
Scaffolding Falls and Collapses
Falls from or through scaffold platforms, scaffold collapses and incidents involving inadequate scaffold erection. Assessment covers scaffold design, erection standards, inspection requirements and the obligations of the principal contractor and scaffold erector.
-
Ladder Falls
Falls from portable ladders and fixed access ladders, including assessment of whether ladder use was the appropriate access method for the task, whether the ladder was set up correctly and secured, and whether ladder use for the task was permitted under the applicable code of practice.
-
Roof and Edge Falls
Falls from unprotected roof edges, through fragile roof materials and through unguarded openings. Assessment covers edge protection requirements, the obligation to identify and protect roof penetrations and fragile surfaces, and the adequacy of fall arrest systems where edge protection was not practicable.
-
Mezzanine and Platform Falls
Falls from mezzanine floors, elevated platforms, loading docks and storage racking. Assessment covers the adequacy of guardrails, gates, toe boards and other edge protection, and whether access and egress arrangements were adequate for the level of traffic and work performed at the elevated area.
-
Elevated Work Platforms
Incidents involving scissor lifts, boom lifts, cherry pickers and other elevated work platforms, including falls from the platform, tip-overs and incidents caused by platform failure or operator error. Assessment covers operator training, platform maintenance, site assessment and supervision requirements.
Hierarchy of Controls for Working at Height
The WHS Regulations require duty holders to apply the hierarchy of controls for work at height. The expert analysis assesses whether the duty holder applied the hierarchy in the correct sequence and whether higher-order controls were considered and ruled out on legitimate grounds before lower-order controls were adopted.
Redesigning the work so that it can be performed at ground level without the need to work at height. Assessment considers whether the task could have been designed differently to remove the need to access the elevated area entirely.
Using engineering controls to prevent a fall, such as installing permanent edge protection, guardrails, cover boards over openings, and fixed access platforms. These controls protect all workers regardless of their actions and are preferred over personal protective equipment.
Safe work method statements, work permits, restricted access areas, supervision arrangements and procedures for working at height where engineering controls are not practicable. Administrative controls rely on worker compliance and are less reliable than physical controls.
Fall arrest harnesses, inertia reels, fall restraint lanyards and similar PPE. PPE is the lowest order of control and is appropriate only where higher-order controls are not reasonably practicable. The adequacy of fall arrest systems depends on correct selection, fitting, anchoring, inspection and maintenance.
Fall Arrest vs Fall Restraint Analysis
Where personal fall protection equipment is used, the expert analysis distinguishes between fall restraint systems and fall arrest systems. These serve different purposes and their adequacy is assessed differently. Selecting the wrong system type is itself a safety failure.
The analysis assesses whether the correct system type was selected for the task, whether the anchor point was adequate for the forces involved, whether the equipment was in good condition, whether the worker was trained in its correct use and whether the system was capable of performing its intended function in the specific work environment.
- Selection of appropriate system type for the task and environment
- Anchor point adequacy for the forces generated in a fall arrest
- Lanyard or connecting component type, length and condition
- Harness fit, condition and pre-use inspection
- Rescue plan in the event of a fall and suspension trauma risk
- Worker training and competency for the specific system used
Understanding the Difference
A system that physically prevents the worker from reaching the fall hazard. The lanyard length is set so the worker cannot reach the unprotected edge. No fall occurs and no arrest forces are generated. Simpler and generally preferred where work permits.
A system that arrests a fall after it has begun. The worker can reach the edge and fall, but the system stops them before they hit a lower level. Generates significant arrest forces on the body, anchor and connecting components. Requires rescue plan.

Does Karim need to inspect the site in a falls from height matter?
A site inspection is recommended in many falls from height matters because the physical dimensions of the elevated area, the anchor point locations, the edge protection details and the access arrangements are often central to the analysis. Where the site conditions are adequately documented in photographs and plans, an opinion can be formed without a physical inspection. Karim advises on whether an inspection is warranted after reviewing the available materials.
-
Can a structural or mechanical engineer be involved as well?
Yes. Falls from height matters sometimes require input from structural engineers where scaffolding collapse or platform failure is in issue, or from mechanical engineers where an elevated work platform malfunctioned. The WHS expert opinion and the engineering opinion address different questions. Karim can coordinate his inspection and opinion with other expert disciplines where instructed to do so.
-
Does the analysis apply to ladder falls as well as scaffold and roof falls?
Yes. Ladder falls are a common category of working at height incident. The analysis addresses whether ladder use was the appropriate access method for the task, whether a safer alternative was reasonably practicable, whether the ladder was suitable, set up correctly and secured, and whether the worker was adequately trained. The Managing the Risk of Falls at Workplaces Code of Practice addresses ladder use specifically and is applied in the analysis.
-
Is a SWMS required for all work at height?
Work at height above 2 metres is classified as high-risk construction work under the WHS Regulations and requires a Safe Work Method Statement. The analysis assesses whether a SWMS was required for the work, whether one was prepared, and if so whether it was adequate for the specific task and conditions. Where no SWMS was prepared for work that required one, this is relevant to the duty holder's compliance with the regulations.
