AUG Risk Analysis

But de la reunion : Prendre en compte: Définir l’emplacement des AUG en fonction des chemins d’évacuation mais aussi des risques et de l’implantation des équipements Définir l’emplacement des points d’éclairage de balisage en fonction des chemins d’évacuation et de l’implantation des équipements Prendre en compte: Ce qui ne doit pas être coupé sur AUG (cheminements dédiés et repérages équipements selon IS5) Combien de chaines AUG sont à implémenter (identification / localisation par les pompiers) fosses – hall cote JURA – hall cote Salève –galerie ? A noter que les AUG dans l’extension doivent avoir la même logique de déclenchement que EHN1 actuel (IS5)

Rappel règles HSE : AUG: The General Emergency Stop (often referred to as AUG, Arrêt d’Urgence Generale) is a level 3 alarm button, which shall cut the electrical power at 18 kV level and inform the fire brigade (see also IS5). It does not trigger the evacuation alarm. The AUG red buttons shall be placed along the corridors about every 25 m, taking into account the AUGs placed on the outside of the PPEs /PPXs (access safety doors of the beam zones), of the ground floor, the first floor, the upper gallery and in the underground galleries of the building. AUL: The AUL shall cut the electrical power of the local area. Such a local area could be a single barrack (e.g. for beam instrumentation (BI) or a clean room or a work shop) or a user’s control room barrack (or group of) together with the associated beam zone(s). The AUL button is placed in the beam zone and the associated barracks. There could be several AUL buttons per barrack group and beam zone (depending on the size). There are also equipment stop button(s), which are not discussed here (e.g. workshops, racks…) and which shall not be confused with an AUL. The AUL only cuts the power of the socket outlets and fixed users’ installations in the respective zone, but does not cut the power of beam line instrumentation (BI) and magnets in there. Latter elements are only stopped using the AUG. BI barracks shall be equipped with their individual AUL.
