What are the flame retardant properties of the surfacing? As part of BS EN 1177, safety surfaces are tested to ensure that if a small source of ignition, such as a lit cigarette or vandals, no damage will be caused to the surface. However, if a fire is started by vandals, you should consider how the surface will react to prolonged exposure to burning debris. Matta surfacing is flame retardant in such situations, ensuring that your playground & surfacing installation is protected as much as possible.
