25.1. Unauthorised entry in BA 1

  • A worker from a

contractor company entered the BA1 site with a member of his family on a Saturday morning

  • He is identified by

the Guards and escorted off-site.

  • His hierarchy has

been notified

4.2.: Safety Barrier removed

  • A safety barrier

blocked PM 56 to prevent access into a cryogenic hazard area

  • An unknown,

unauthorised person removed the barrier

  • Later, an

unsuspecting staff member entered the hazard area by PM 56

Statistical Indicators

  • Most accident victims are contractor’s personnel, but

accidents are 6 times less severe as usual

  • The excellent preparation of the works and the

thorough training of the workers by the CERN LS-1 teams was worth the effort.
