The purpose of this Safety Regulation is to define the principles governing the declaration and management, including the notification, classification, analysis and follow-up, of Safety Incidents at CERN with a view to mitigate their consequences, both immediate and long term, and to avoid re-occurrence through corrective actions and sharing of lessons learnt.

The purpose of this Specific Safety Instruction is to define the principles governing the classification, investigation, analysis and follow-up of Major Safety Incidents.

The object is to define safety alarms and to establish general rules for the installation, maintenance, disabling, and layout of safety alarm systems generating level 3 alarms. The EDH version of the disabling form is now mandatory.

Description of the two types of emergency stops (general and local emergency stops), definition of the buildings or areas to be equipped, and effects due to these emergency stops on power supplies or accelerators. Exceptions and rules for safety equipment.

This Safety Guideline provides guidance as to the implementation of the CERN Safety Regulation “Responsibilities in matters of Safety Incident Management at CERN” (hereafter SR-SIM).

In some cases the regulatory framework of a certain domain can be exhaustive and challenging to implement. This document provides further interpretation on CERN safety requirements, related to evacuation procedure and principles on the French territory of the CERN site, as well as recommendations on best practices to be used on CERN sites.
