The main messages I can draw from this, is to encourage subscription to the adequate safety training for you and the people concerned in your section, and to ask you to make sure that untrained/inexperienced persons are not left alone in a potentially hazardous zone (in that case, I'm especially thinking of the future Russian teams that will install BI equipment in the LHC). Cheers, Roland ---------------------------------------------------------------------------- ---- From: Paolo Cennini [mailto:Paolo.Cennini@cern.ch] Sent: Wednesday, February 15, 2006 17:25 To: ab-mgt-abic (List for AB Installation Committee) Subject: Commissioning of electrical Equipments On Feb 15, 2006, at 5:13 PM, Paolo Cennini wrote: During the commissioning of Electrical Equipments, starting in this period after a long shut-down, the risk of electrical dangers is increased. The aims of this note is to remind the safety rules to be followed for the persons non specialized needing to access area where some Electrical Equipments are operational. The complete information on this subject could be found in the SC web site (Code C1.6 and 7, and Safety Instruction IS24) and on the site Legifrance http://www.legifrance.gouv.fr/texteconsolide/SHHDD.htm It is important to notice that most of the equipments in the accelerator tunnels are non-standard, and therefore the elements used to ensure the Protection of Personnel should be agreed by the SC. In case the appropriate protections are in place, no particular training is required for the persons accessing the area with the equipments switched ON. In case the parts used to protect the equipments are not in agreement with the safety standards, the presence nearby of non qualified persons is not allowed unless this equipments are formally "hors tension" (Décret 88-1056, 48 and 49). In case the access is needed with equipments switched ON, the non qualified persons could be accompanied by an authorized person (Décret 88-1056, 25). The hierarchy is responsible to ensure that the persons requested to intervene in a potentially dangerous area are correctly trained (Décret 88-1056, 46 II). The courses needed to obtain the required qualification are organized by the SC. Concerning the safety on the field (complementary to the formal qualification), the most important guidelines to be followed under the present circumstances are: - Clear definition of the area where the tests are done. - Installation of warning signals (to be removed at the end of the test). - Mechanical lock of the concerned areas. - Scheduling provided in advance to avoid overlaps between the electrical tests and other activities in the same areas. - Spread of information on the planned electrical tests. - Direct information to the person on the dangers specifics to the area. - Instructions to the CCC in case an intrusion in the area is detected. Hoping this short note will help to work in the best possible safety conditions, best regards, your DSO. ---------------------------------------------------------------------------- -------------------------------------------------- Pendant la mise en service des appareillages électriques, qui commence dans cette période après un long arrêt, le risque lié à des dangers électriques est plus élevé que d'habitude. L'objectif de cette note est de rappeler les règles de sécurité qui doivent être suivies par le personnel non spécialisé pour accéder au secteur dans lesquels des appareillages électriques sont opérationnels. L'information complète à ce sujet peut être trouvée dans le site Web de SC (code C1.6 et 7, et instruction de sécurité IS24) et sur le site Legifrance http://www.legifrance.gouv.fr/texteconsolide/SHHDD.htm Il est important de noter que la plupart des équipements dans les tunnels d'accélérateur sont non standard, en conséquence les éléments employés pour assurer la protection du personnel doivent être agréés par SC. Dans le cas d'équipements protèges selon les normes, il n'y a pas des restrictions pour accéder dans les zones avec d'équipements sous tension. Au cas où les pièces employées pour protéger les équipements ne seraient pas en accord avec les normes de sécurité, la présence des personnes non qualifiées en proximité n'est pas autorisée, à moins que ce les équipements soient mis formellement "hors tension" (Décret 88-1056, 48 et 49). Dans le cas de besoin d'accès avec des équipements sous tension, les personnes non qualifiées peuvent être accompagnées par une personne habilitée (Décret 88-1056, 25). La hiérarchie est responsable d'assurer que les personnes intervenant dans un secteur potentiellement dangereux soient correctement formées (Décret 88-1056, 46 II). Les cours pour obtenir les qualifications exigées sont organisés par SC. Pour ce qui concerne la sécurité sur place (complémentaire à la qualification formelle), les directives les plus importantes à suivre dans les circonstances actuelles sont : - définition précise du secteur où les essais sont faits. - installation des signaux d'alarme (qui doivent être enlevés à la fin des essais). - fermeture à clef des secteurs intéressés. - établissement du programme défini à l'avance pour éviter des chevauchements entre les essais électriques et d'autres activités dans les mêmes secteurs. - diffusion d'information sur les essais électriques prévus. - l'information directe à la personne sur les détails de dangers au secteur. - instructions au CCC au cas de détection d'une intrusion dans le secteur. En espérant que cette note aidera à travailler dans les meilleures conditions de sécurité possibles, meilleures salutation, votre DSO. -----Original Message----- From: Enrico BRAVIN [mailto:enrico.bravin@cern.ch] Sent: Friday, 17 March 2006 12:34 To: Roland Garoby Cc: Jean-Jacques Gras; Alan Burns; Bernd Dehning; Claude Fischer; Jens Spanggaard; Rhodri Jones; Uli Raich Subject: Re: Habilitations Electriques Hello, I had a discussion with people in my section this morning concerning this subject. I might have missed something, but I have not a clear picture of who needs it or if this has been clarified (that's why I never sent the list). Apparently (info from L.Rinolfi) everybody entering the machines needs it! (or better at least one person in a team operating on the machine needs it which practically is the same). I have heard (again from Luis) that there are courses starting next week and the list of participants must come from the GL. Other people have followed a course proposed on EDH. Are these the same thing? If the situation is the one depicted by L.Rinolfi I think everyone in the section (probably group) should be put on the list of Roland. -Enrico Roland Garoby wrote: >> Jean-Jacques, >> >> It certainly needs clarification, else everyone entering the tunnel will >> be concerned.
