2. Safety Policy at CERN

• The safety policy is defined in the document
  SAPOCO-42
• http//safety-commission.web.cern.ch/safety-comm
  ission/sapoco42/index.html
• 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 !

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.

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

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 projects development through to
  its dismantling and final disposal.

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...
• 5.6. Visitors are bound by their presence on the
  Organizations site to comply with the safety
  regulations.

• 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.

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 !

37
Handling, Manipulation

  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.

• 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.

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 http//service-rp-shipping.we
  b.cern.ch/service-rp-shipping/
• Wear your CERN film-badge whie working with
  sources
• The SC-RP Group is responsible for the
  elimination of all radioactive waste.
