    This Safety Guideline is intended to assist with understanding and applying General Safety Instruction GSI-SH-1 "Visits on the CERN site", version 2. This guideline is partly based on comments, questions and remarks gathered during the consultation phase of the Safety Rules drafting process.

  • SG-SH-2-0-1

    Guide for the implementation of GSI-SH-2 - Lone working

    This Safety Guide is an aid to the understanding and application of General Safety Instruction GSI-SH-2 - Isolated Work, version 1.
    This guide is based in part on the comments, questions and comments gathered during the consultation phase as part of the GSI-SH-2 General Safety Instruction - Isolated Work, or following its publication .

  • SG-SH-4-0-1

    Noise at the workplace

    This Safety Guideline provides guidance as to the implementation of Safety Rule GSI-SH-4 “Protection of Workers against Noise” in particular with regard to the evaluation of the Noise exposure risk of Workers and Noise control.

Safety Forms (SF)

  • Disabling of level 3 alarm

  • OHS-0-0-3

    Identification of occupational risks

  • SF-OHS-0-0-1 et 0-0-2

    Risk assessment

    The purpose of these Safety Forms is to aid in the implementation of the risk assessment process laid down in the framework of the Safety Regulation SR-OHS - Occupational Health and Safety.

  • SF-SH-0-0-8

    Event

    This Safety Form is to be completed by the organiser of an event to inform the HSE Unit and provide the data needed for defining security requirements.

    When necessary safety inspections (general, electrical, structural, etc.) will take place before the start of the event.

    To help you in organising your event, the Safety Guide "15 key issues to address the safety aspect of your event" is available on the official website of safety rules (https://edms.cern.ch/document/1274277/4).

  • SF-SH-1-0-1
