Safety Instruction

IS 22 - Rules for the safe use of lasers at CERN (1994) en fr
The radiation produced by lasers may be hazardous to the human eye and skin. It may also present fire or explosion risks. Lasers have been classified according to their exposure hazards. Conditions for use and warning labels and notices are recorded.
IS 36 - Safety Rules for the Use of Static Magnetic Fields at CERN (2005) en fr
Studies on workers exposed to static magnetic fields have indicated various subjective symptoms and functional disturbances. This instruction recalls some of the technical hazards encountered, and informs on exposure limits and on the safety procedures for operating magnets. Following the publication of Directive 2013/35/EU of the European Parliament and of the Council of 26 June 2013, the exposure limits for occupational exposure defined in paragraphs 5 and 6 of IS36 rev. 2 shall be amended as defined below. All other provisions of IS36 Rev. 2 remain valid including the principle that exposure shall be kept “As Low as Reasonably Achievable (ALARA)”. Occupational exposure limits: Exposure limits under normal working conditions are B = 2 T and B = 8 T for localised limbs exposure, B being the magnetic flux density. Exposure below the above indicated limits does not require a specific medical authorisation or follow-up. (Memo EDMS 1466042)
