20 FRAMING AND ROOFING A safety device must be put in place before working on a roof for protection in case of slips or falls. The type of system is determined by the length of the operation. If the operation is long, it should be protected by collective protection in order to eliminate any risk of falling. If it is a short-term, temporary operation, individual protection is used. PPE is generally necessary for installing the collective protection, if the building is not already equipped with it. In this situation, there is a great risk of falling. Each person must use a fall arrest system (for example, energy absorber with mobile fall arrester and safety rope). If collective protection is present and adequate for fall protection, a work positioning system with adjustable lanyard is the perfect solution. VERTEX BEST and VIZIR SHADOW With its strong chinstrap, the VERTEX BEST helmet sets the standard in head protection for workers at height.

Its six-point webbing suspension ensures comfort, and its CenterFit adjustment system adjusts the headband and keeps it centered on the head. The VIZIR SHADOW visor ensures eye protection and integrates perfectly into the helmet. It has a level 2.5 solar protection filter with anti-scratch and anti-fog treatments.
