The fundamental function of a safety handle for fire doors is to guarantee opening of the door itself during and after a fire. At any time, the rescue teams must in fact be able to open the doors that separate the areas at risk. It is therefore crucial that functionality and resistance are guaranteed both for the door and for the components of the same. The regulation in force for this area establishes increasingly restrictive provisions to protect safety. (Official Journal no. 271 of 18.11.2004).
