NOTICE OF START OF WORK (AOC)

Work to be done by contractors on the CERN site must be announced by means of a Notice of Start of Work called AOC (Avis d'Ouverture de Chantier, pdf) issued by the work supervisor (member of the CERN personnel supervising the work or outside supervisor mandated by the Organization).

The AOC forms is an important part of the risk prevention plan. The AOC is sent to all CERN services and all persons concerned, both to obtain their comments and to inform them and draw their attention to the risks and any constraints associated with the worksite (see Safety Instruction 39).

If in case of doubt about the need for an AOC, supervisors must consult SC-GS-SI.
