Working Safely on Fragile Roofs

Skylight Covers and Walkway

Falls from heights still continue to be one of the biggest causes of serious injury or fatality in the workplace. Safe Work statistics show that falls contribute to the death of one person and serious injury of about 300 workers every two weeks.

Most of us understand that working with two metres of an exposed edge requires the use of a fall arrest harness system. But what about the hidden dangers. As they can be hard to identify, working on or around fragile or brittle surfaces exposes workers to a risk of a fall through a surface, that may normally be considered safe.

Recent reports out of the UK state that falls through fragile surfaces account for 22% of all fall from height fatal injuries in the construction industry. This has been highlighted in South East Queensland by a recent fatal accident as well as a number of serious falls including one of about 14m.

As they can be hard to identify, working on or around fragile or brittle surfaces exposes workers to a risk of a fall through a surface, that may normally be considered safe.

Safe Work Australia noted that there are several materials which present a greater risk of becoming fragile. These include asbestos roofing sheets, polycarbonate or plastic, fibre cement sheets, wood slabs, glass and metal sheets. This is certainly not an exhaustive list. Safe Work Australia states that “all roofs should be treated as fragile until a competent person has confirmed they are not”.

Likewise, skylights are not designed to support the weight of a person. They should always have guardrail protection, skylight protectors or safety wire mesh installed. Corrugated polycarbonate sheeting is rarely structural and not suitable to walk on. Ultraviolet light may cause further degradation of the sheets.

Control Measures

Control measures, to prevent falls through fragile roofs, are like those used for general roof work and include using:

  • An elevating work platform so workers can avoid standing on the roof itself
  • Barriers such as guardrails or covers that are secured and labelled with a warning
  • Guardrails fitted to all work and access staging or platforms
  • A harness system with adequate anchorage points, along with appropriate training and supervision.

Care must be taken if safety mesh is relied on for fall protection. You must ensure it:

  • Conforms to AS/NZS 4389:2015 Roof safety mesh
  • Is installed by a competent person in a safe manner and in accordance with the manufacturer’s instructions
  • Has its integrity inspected by a competent person prior to roof maintenance or removal

Permanent warning signs should be installed at every likely access point to the roof warning of the presence of fragile roofing materials.
