Falls through fragile roof surfaces, particularly rooflights and fibre-cement roofs, are one of biggest causes of serious injuries. Work at height is by nature high risk, but work on fragile surfaces is even more dangerous. Effective precautions must be taken for all work on or near fragile surfaces, no matter how short the duration. Accidents can be avoided as long as suitable equipment is used and those carrying out the work are provided with adequate information, training and supervision.
Access onto a roof is often required for maintenance, inspection, cleaning or general repairs. Fragile surfaces are typically found on factories and warehouses and can include:
- Roof lights and skylights
- Corroded metal sheets
- Non-reinforced fibre cement sheets
- Roof slates and tiles
- Glass such as wired glass
Working on fragile surfaces
The principles of working on fragile surfaces are exactly the same as any other form of work at height, you need to apply the hierarchy of control to ensure that the work can be carried out safely.
In an ideal world, the preferred option is to avoid working at height, but this isn’t always possible, so the next consideration would be to look at methods which could allow work to be carried out without actually stepping onto the fragile roof itself, such as Mobile Elevating Work Platforms (MEWPs).
If access onto the fragile roof cannot be overcome then you will need to conduct a thorough Risk Assessment and look at how the area can be accessed safely, and then put into place measures that can alleviate the distance and consequences of a potential fall.
This can be done in a number of ways, such as protecting the edge of the roof with guardrail, using staging or platforms with edge protection on the roof to spread the load or by protecting fragile roof lights and skylights with a cover to prevent access onto the surface itself.
When access is needed from the eaves to the ridge, mesh walkways spread the load across the support battens, giving workers a safer working position.
A safe working platform for fragile roofs
Mesh walkways are a great option when access is needed to run from the eaves to ridge. It provides the benefit of spreading the weight across the support battens, allowing the workers to confidently move along the full length of the system. Opting for a solution that is made from high grade aluminium ensures the structure is robust, lightweight, and easily transportable.
Board-Walk open mesh walkway
Board-Walk - our open mesh walkway system has been designed specifically to allow work to be carried out safely on fragile and industrial roofs. The system allows access from the eaves to ridge, whilst spreading the load on support battens to provide the user with a safer working position. The system is lightweight and easily portable, making it ideal for use on fragile roofs. The Board-Walk system is compliant with EN12811-1.
Board-Walk is modular and features 1m, 2m, 3m & 4m sections which are quickly and easily linked together and an integral full length work positioning line. Single or double sided handrails, a roof hook and a valley stop end are all available as extras.
