Everybody is responsible for safety. CERN has a formal safety policy and the Staff Rules and Regulations require you to be familiar with, and to comply with it.

Safety Communications Noticeboard

Regular Safety Communications for the IT Dept can be found on CERN Notifications at IT Dep Safety Communications.

IT-specific risks

For most people in IT, the greatest danger is from the usual occupational hazards---slipping, falling and the risk of fire. So, make sure you know the evacuation procedures and behave sensibly - don't climb up on a wobbly chair to reach the top of your bookcase! (Simple falls are the most common form of accidents at CERN.)

The machine room in areas in B513 and B613 have special risks:

  • the false floor - removing false floor tiles creates a hazard for others and care is needed when working under the false floor.
  • lifting heavy objects - recommendations are given in the 'Related Document' section.
  • special equipment - such as the STK silos or the motorised "clerk" used for lifting palettes - operating instructions for the server lifting equipment are contained in the 'Related Document' section.
  • electrical risks - not all sockets are protected with differential circuit breakers. 
  • noise - a document describing noise awareness measures for the CERN Data Centre is given in the 'Related Document' section
  • last, but not least, a fire here puts the CERN programme at risk.

People with access to the machine room must be aware of the rules that apply here.

Office environment

Safety at CERN also covers issues of ergonomics - your office environment should be comfortable and not damaging to your health.

So, make sure your chair is safe and that your desk is set up correctly for using a keyboard and monitor - see Adjusting Your Workstation.
