Framing and roofing

Before doing any work on a roof, workers at height must install safety equipment to protect themselves from the risk of sliding or falling. The type of system is determined by the length of the intervention. When the intervention is long, safety should be ensured with collective protection which eliminates all risk of falling; when the intervention is limited and short, safety is ensured with individual protection (Personal Protective Equipment is necessary in both cases if the building has not previously been equipped with collective protection, as it will protect the workers who install it).

In the absence of collective protection, the risk of falling is real, and the worker must use a fall arrest system (composed of an energy absorber, a mobile fall arrester and a lifeline).

If collective protection is present (safety nets, etc.), the worker can install a work positioning system (adjustable lanyard).
