Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 3 1. Scope of “Safety” at CERN Safety at CERN includes  Occupational health, hygiene,  Environmental protection,  new  Work safety, operational safety,  Safety of equipment and installations.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 4 2. Safety Policy at CERN  The safety policy is defined in the document SAPOCO-42  Everyone at CERN (= staff members, users, collaborators, contractors…) is place under the authority of the DG.  Everyone must be trained/informed about safety ( Read the Safety Plans )  Anyone facing an hazardous situation must report about it.  Think Safety – Work Safely !

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 5 2. Safety Policy at CERN  Responsibilities in matter of safety follow the managerial line; each supervisor/project leader is responsible for his team/project.  Safety Officers (DSO, FGSO, RSO…) are nominated to help supervisors.  Safety Commission and Safety Committees give advice and control. DG / CEO PH Dept Head Tech. Coord. / GLIMOS Project Leader Project Engineer Designers, staff, users…

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 6 2. Safety Policy at CERN  Responsibilities in matter of safety follow the managerial line; each supervisor/project leader is responsible for his team/project.  At Point-2, the installation of the Experiment is under the responsibility of TS Dep-t. Hence, the reporting line of safety is the following: DG / CEO TS Dept Head Experimental Area Manager WP Engineer WP Supervisor Workers, technicians, users…

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 7 2. Safety Policy at CERN Safety Officers for ALICE :  GLIMOS = Group Leader in Matter of Safety checks the design and co-ordinates all safety aspects. Disseminates and collects the info related to safety. GLIMOS = Marc. Tavlet, Deputy = Hans Taureg Note : general phone No for GLIMOS =  INB link-person co-ordinates the aspects of the “Installation Nucleaire de Base” (mainly traceability) J-P. Vanuxem

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 8 2. Safety Policy at CERN Safety Officers for ALICE :  FGSO = Flammable Gas Safety Officer, checks the design and installation of (flammable) gas distribution. Ch. Gregory  RSO = Radiation Safety Officer, checks the safety related to ionizing and non-ionizing sources, including lasers. M. Tavlet  TSO’s = Territorial Safety Officers checks the daily safety aspects. At Pt 2, TSO = Sebastien Evrard deputy = Didier Anstett For other TSO’s, consult “Safety Officers Support” on the web

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 9 2. Safety Policy at CERN Some exerts from SAPOCO-42 :  Each of us must work so as to run the least possible risk and, to this end, must actively obtain a maximum amount of information to enable us to do so.  Anyone who introduces new equipment, materials or techniques must check any safety problems which may arise with their Group Leader (or GLIMOS) and Divisional Safety Officer (DSO ), and if necessary seek the advice of the Safety Commission... [# 1.10]  Supervisors are responsible for all matters of safety, occupational health, and protection of the environment connected with their activities or project […] ensuring that [collaborators] are kept fully informed of and if necessary trained in the safety aspects of their work.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 10 3.Safety Rules  CERN, as an International Organization, has settled its own safety rules, based on European Directives or on rules in force in the host states.  In case CERN regulations are lacking or incomplete, the regulations of the host state concerned are applicable.  Ex.: Road traffic rules

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 11 4.Safety for Experiments Some exerts from SAPOCO-42 : 4.3.Anyone in charge of a project must establish a safety structure which includes an appropriate delegation of task together with the corresponding authority. 4.8.Project Leaders are responsible for safety in their project. They must ensure that all safety requirements have been taken into account from the design stage and subsequently at all stages of their project’s development through to its dismantling and final disposal.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 12 4.Safety for Experiments Some more exerts from SAPOCO-42 : 5.1.Experiments, facilities, and tests must comply with the safety regulations in force at CERN in connection with the construction, operation, and disposal of equipment. 5.4.For safety matters, an experiment or test is represented by a Group Leader in Matter of Safet (GLIMOS), who is responsible for safety, with the necessary authority Visitors are bound by their presence on the Organization’s site to comply with the safety regulations.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 34 Electricity  Electrical hazards (electrocution, damage to property) are to be encountered almost everywhere.  Persons carrying out work on electrical installations must have the necessary qualifications.  Safety Code C1, "Electrical Safety Code", lays down the regulations concerning electrical construction work and for the installation and use of electrical equipment.  Safety Instruction IS 24, "Regulations applicable to Electrical Installations", specifies the standards in force on the CERN sites.  In practice : If you don’t know, don’t touch !

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 35 Fire  Safety Code E, "Fire Protection  Fires  activities creating "hot spots  "fire permit" - person requesting the work - TSO responsible for the area  The combustion of plastics containing halogens, sulphur or phosphorous releases corrosive gases that often cause more damage than the fire itself.  Safety Instructions IS 41 and IS 23  Know the location of the alarm systems and fire-fighting equipment in the vicinity of your workplace and know how to use them.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 36 Transport, Lifting  Use as much as possible the official services for transportation of heavy materials and delicate equipment  “demande de transport interne” on EDH They have the know-how and an insurance.  The use of lifting equipment (cranes, forklifts…) requires training and qualification !

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 37 Handling, Manipulation  Think before acting !  Watch your hands !

38  Read the Material Safety Data Sheet, MSDS  hazards, precautions, emergency procedures  Delimit the zone before work commences,  Ventilate the work place,  Wear the appropriate gloves as well as an apron and safety goggles.  Use the minimum amount of chemicals for the job.  Fire extinguisher, absorbent product (Hi-dri…) at hand.  Eye wash must be present at the work place.  Store (unused) chemicals in appropriate containers.  In case of doubt, contact SC/GC. Chemicals

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 39 Radiation in test beams  Safety Code F = Radiation Protection Manual  Working in “controlled areas” observe the information on the panels wear your CERN film badge organise your work as to minimise the exposure of personnel. never remove shielding, protections or locking systems report any anomalies to the person responsible for the equipment. Any material leaving an accelerator area may have been activated. It must therefore be checked by SC-RP.

Induction Safety Course for ALICE Collaborators - Marc TAVLET / GLIMOS 40 Radiation from sources  Safety Code F = Radiation Protection Manual  Radioactive sources must be registered by SC-RP  Transport and shipping of sources must be organised by SC-RP  Wear your CERN film-badge whie working with sources  The SC-RP Group is responsible for the elimination of all radioactive waste.
