Ladder SWMS — Safe Work Method Statement for Ladder Use on Construction Sites
A Safe Work Method Statement (SWMS) for ladder use is a mandatory safety planning document required under the Work Health and Safety (WHS) Regulation 2025 whenever a ladder places a worker at risk of falling more than 2 metres. Portable ladders are the most common — and most misused — means of access on Australian construction sites. Safe Work Australia injury data consistently identifies ladder falls as a leading cause of lost-time injury in construction, and the pattern is stubbornly consistent across every jurisdiction: the ladder was the wrong tool for the task, the setup was incorrect, the base was unsecured, or the worker over-reached from the side rails. In almost every serious ladder incident the root cause is not a defective ladder — it is a selection and use decision made before the ladder left the vehicle. Under the WHS Regulation 2025, the hierarchy of controls places the ladder as the last-resort access method for work at height. Before selecting a ladder, the risk assessment must demonstrate that higher-order controls — eliminating the need for height access, prefabricating at ground level, installing an elevating work platform, or erecting a scaffold — are not reasonably practicable for the specific task. The Code of Practice: Managing the Risk of Falls at Workplaces (2021) is explicit that a ladder is acceptable only where the work is of short duration, the worker can maintain three points of contact, the task is light (no significant push, pull, or lateral force), and no other control is reasonably practicable. These four conditions are cumulative, not alternative. Ladder selection and use in Australia is governed by the AS 1892 series — AS 1892.1:2018 for performance and geometric requirements, AS 1892.2 for timber ladders, and AS 1892.5:2020 for the selection, safe use, and care of portable ladders. Domestic-rated ladders are not permitted on construction or industrial sites — only industrial-rated ladders (rated to 120 kg minimum) are acceptable. Where electrical hazards are present, a fibreglass or non-conductive ladder is mandatory because metal ladders in contact with an overhead conductor are lethal. The SWMS must nominate the specific ladder duty rating, material, and type, and the site inspection procedure for verifying condition before each shift. This pre-filled ladder SWMS template has been developed in accordance with the WHS Act 2011, WHS Regulation 2025, the Code of Practice: Managing the Risk of Falls at Workplaces (2021), AS 1892.1:2018, and AS 1892.5:2020. It is designed for construction contractors, principal contractors, and PCBUs whose workers use ladders on site for short-duration access and light work. The template provides a compliant framework that must be reviewed, customised for the specific site and task, and developed in consultation with workers before use. A generic SWMS that has not been made site-specific does not satisfy the requirements of the WHS Regulation and is routinely cited as a compliance failure in regulator prosecutions.

Hazards
| Hazard | Consequence | Likelihood |
|---|---|---|
| Fall from ladder due to over-reaching beyond the side rails | Over-reaching shifts the worker's centre of gravity outside the base of support of the ladder and induces a lateral tipping failure. Outcomes include fracture of wrist, forearm, ribs, and pelvis, head injury from impact with the ground, spinal injury, and death. Safe Work Australia injury data identifies over-reaching as the most common proximate cause of ladder-related fall injuries. A ladder fall from as little as 1.5 metres onto concrete has produced fatal head injuries. The instinctive response to a tipping ladder is to try to regain balance, which usually results in a harder landing than if the worker had pushed away from the structure. | Likely (B) — over-reaching is a habitual pattern that increases with fatigue, task pressure, and workers' perception that repositioning a ladder is a time-cost they can avoid |
| Ladder base slip or slide on smooth, wet, polished, or contaminated surfaces | Extension ladders are inherently unstable if the base moves. When the ladder base slides outward on a smooth or wet surface, the ladder rotates downward and the worker falls an amount equal to the ladder's length along an arc. On polished concrete, tile, or oily surfaces, even a small disturbance can initiate the slide. The ladder feet themselves provide limited friction on these surfaces. Base slip is a common feature in coronial findings on ladder fatalities. | Possible (C) — elevated on wet construction surfaces, polished concrete slabs, and gravel or loose aggregate |
| Fall due to incorrect ladder setup angle outside the 4:1 ratio specified in AS 1892.5:2020 | An extension ladder set too steep (angle greater than 75 degrees from horizontal) places the worker's weight directly above the base and can induce a backward tipping failure when the worker shifts body position. A ladder set too shallow (angle less than 70 degrees) places excessive horizontal load at the base, which slides out under the weight of the worker. Both failure modes produce uncontrolled falls, typically with the worker striking the ground head-first or landing on the upper back and shoulders. | Possible (C) — compliance with the 4:1 rule is widely understood but inconsistently practised |
| Ladder structural failure during use — rung collapse, side rail fracture, locking catch failure, foot detachment | Ladder structural failure during active use produces a sudden uncontrolled fall from the height at which the failure occurred. Domestic-rated ladders used on construction sites are a common source of structural failure because their design load and fatigue life are unsuitable for sustained commercial use. Fibreglass side rails crack internally when exposed to UV without being visible on the surface. Rope-and-pulley extension locks wear and release unexpectedly. Aluminium rung-to-rail joints fatigue and fail under repeated load. | Unlikely (D) for an inspected industrial-rated ladder — but Possible (C) where ladders are not formally inspected, where domestic-rated ladders are used, or where ladders remain in service past their replacement date |
| Workers below struck by tools, fasteners, or materials dropped from a ladder user | A dropped tool or component from as little as 3 metres carries enough kinetic energy to cause skull fracture and traumatic brain injury to a worker below. A 1.5 kg hammer dropped from 5 metres impacts with force equivalent to several times its static weight. Dropped objects are a persistent site hazard wherever ladder work occurs above active work areas or pedestrian routes, and exclusion zones are frequently absent or ignored. | Possible (C) — elevated when tool management is not enforced or when other trades work in proximity |
| Electrical contact between a metal ladder and an overhead power line, live electrical service, or exposed conductor | Contact between a metal or wet timber ladder and an energised conductor is almost always fatal. Distribution voltage conductors (11 kV to 33 kV) deliver an immediately lethal electrical shock. Even 230 V contact from a stripped cable or damaged light fitting can cause cardiac arrest and electrocution. The worker on the ladder, any worker on the ground touching the ladder, and any metallic structure the ladder is leaning against can all enter the fault path. Multiple fatalities occur each year in Australia from ladder-to-overhead-line contact during construction, tree pruning, and maintenance work. | Unlikely (D) — but consequence is catastrophic; risk elevated on urban sites with close overhead distribution lines and on any worksite with exposed electrical services |
| Manual handling injury from lifting, carrying, repositioning, and raising extension ladders | Industrial extension ladders exceeding 6 metres in length can weigh 20 to 30 kilograms and are awkward for a single worker to raise and lower vertically. The raising action places a peak load on the lower back at the moment of transition from the horizontal to the vertical. Acute lower back strain, lumbar disc injury, and shoulder injury are common outcomes, and cumulative strain over a career causes chronic musculoskeletal conditions that are a leading cause of workers compensation claims. Raising a tall extension ladder alone is a recognised high-risk activity that AS 1892.5 identifies as requiring two workers. | Likely (B) — single-worker ladder raising is endemic despite the two-person guideline |
| Falls during transition from ladder to an adjacent working surface such as a roof, scaffold, or platform | The transition from a ladder to a roof or platform is the single most hazardous moment of the climb. The worker must release three points of contact from the ladder, step across to the adjacent surface, and re-establish grip on the new surface. At this moment the ladder is most likely to slip, the worker is most likely to lose balance, and the adjacent surface may not provide the expected handhold. A large share of ladder-fall serious injuries occur at this transition point. | Possible (C) — elevated when the ladder does not extend 1 metre above the landing point or when the landing point lacks a handhold |
| Slips on ladder rungs from contaminated boot soles, wet rungs, or mud | Mud, oil, paint, or water on the rungs or on the worker's footwear reduces the friction at the foot-rung contact and can initiate a slip. The worker may recover with a hand-grip save but is more likely to fall some distance before regaining three points of contact or strike the ground with full force. Dirty boot soles are a preventable factor that is rarely addressed in pre-use checks. | Possible (C) — routine on wet construction sites and when workers transition between mud and clean surfaces |
Controls (Hierarchy of Controls)
Recent Prosecutions
SafeWork NSW inspectors visited 1,218 construction worksites as part of a targeted falls-from-heights enforcement programme, with a particular focus on ladder use, scaffold integrity, and edge protection. The programme issued 1,499 improvement notices, 727 prohibition notices, and 352 penalty notices totalling $972,000 in fines. Common ladder-related findings included untagged and unmaintained ladders, domestic-rated ladders used in commercial settings, ladders used as work platforms for sustained tasks, and absence of a site-specific SWMS for work at height.
2024 — SafeWork NSW Falls from Heights Enforcement Programme Media Release 2024
A maintenance company was fined $33,000 following a SafeWork NSW prosecution in relation to a fall-from-height incident involving a worker who fell from a ladder while performing routine building maintenance. The court accepted that the PCBU failed to provide a safe system of work, did not prepare a SWMS for the high-risk construction work, and had not ensured the ladder was secured or the fall hazard was otherwise controlled. The prosecution followed a compliance review triggered by the injured worker's workers compensation claim.
