Fall through asbestos roof (10 September 2018)
10 September 2018
Fall from height through roof
A 26 year-old labourer was on the roof of a home helping remove asbestos cement corrugated roof sheeting when one of the sheets gave way and he fell approximately 4 metres.
The fall-arrest system used did not prevent the worker from hitting the wooden floor below. The worker sustained a suspected broken wrist.
SafeWork NSW and NSW Ambulance responded to the incident and the worker was taken to hospital and received treatment for his injuries.
The site is located at Newcastle East. The activity being undertaken at the time was the removal of asbestos roof sheeting on a residential dwelling. The site is under the control of a principal contractor with a sub-contractor engaged to undertake demolition and asbestos removal at the site.
SafeWork NSW Inspectors responded to the incident
Our Prosecution Guidelines outline our approach to prosecutions and Safe Work Australia’s National Compliance and Enforcement Policy provides guidance on their approach to compliance.
These documents set out factors that will be considered in determining the investigative approach and appropriate outcome.
Businesses and workers are reminded of their duty to identify hazards and manage risks to health and safety in accordance with the provisions of the Work Health and Safety Act 2011 and Work Health and Safety Regulation 2017.
Each year SafeWork NSW respond to incidents where workers have died or been seriously injured from falls from heights. Many of these incidents involve falling through roof material. Asbestos cement roof sheeting is known to become brittle with age.
Businesses are reminded to consider reasonable and practicable control measures to manage the risk of falls.
Before starting work on an existing roof, carry out an inspection (from below) to determine:
- the presence and condition of non-trafficable sheeting such asbestos cement sheeting and other brittle roof sheeting such as sky lights or plastic roof sheeting
- for residential properties, the spacing and condition of roof purlins or trusses, including any gaps in purlins
- for commercial properties, the presence and condition of safety mesh.
When determining whether roofs are safe to walk on, consider that product materials may become brittle with age and fixings may become less rigid over time.
Control measures to prevent a person from falling through a non-trafficable roof or skylight include:
- plan to work from below whenever possible
- plan the work to avoid accessing unsafe or non-trafficable areas
- work from an elevated work platform or boom lift to avoid standing on the roof itself
- install temporary work platforms (crawling boards) and roof ladders as appropriate
- install barriers (such as guard rails or covers) that are secured and labelled with warning signs
- install safety mesh when installing the roof sheeting
- install a fall arrest system (harness system) which has adequately-installed anchorage points, along with training and instruction in the use.
- ensure workers using an adjustable length (traveller) fall arrest system are competent and aware that the rope line is to have minimal slack, to protect then in the event they fall through, when walking or working on roofs and are aware of the pendulum effect when using single anchorage points.
Ensure the selected control measures are being consistently applied and review the control measures as work progresses.
