Prévention des incendies dans le cas des structures de panneaux sandwich à âme isolante pour utilisation en intérieur Directives pour la sélection, l’installation et l’utilisation (2004)
La présente note donne les prescriptions de sécurité pour la conception, la construction et l'utilisation de structures de panneaux sandwich à âme isolante. Elle fournit également des mesures complémentaires pour l'adoption, en tant qu'âme isolante, de matériaux dont l'utilisation est soumise à l'Instruction de Sécurité IS 41.

Fire prevention for enclosed spaces in large halls (2001)
Recommendations for the choice of materials, installations and use of these large halls, and reminder of fire prevention actions to be taken.
Safety Instructions (IS)
- IS 23
Criteria and Standard Test Methods for the Selection of Electric Cables and Wires with Respect to Fire Safety and Radiation Resistance (2005)
This instruction is based on the latest standards and recommendations to ensure a very high level of safety against hazards associated with smoke, toxicity and corrosivity from burning plastics. It summarizes the required properties for the different materials and cable types and is applicable to all types of cables and wires and other insulated parts to be used in CERN installations.
- IS 41
The use of plastic and other non-metallic materials at CERN with respect to fire safety and radiation resistance (2005)
This instruction is intended to ensure a very high level of safety and must be applied to all new installations at CERN, including modifications to existing installations. CERN attaches great importance to the hazards associated with the density, toxicity and corrosiveness of smoke from burning plastics. The document is complemented by tables of standards and specifications for the selection of plastics, and guidelines for their use.
- IS 48
Fire prevention for cables, cable trays and conduits (2001)
This Safety Instruction defines rules and other preventive measures for cable fires. It lists the most common fire risks for cables and conduits. Mandatory precautions are specifically aimed at preventing cable fires in physics experiments where confined spaces, higher vicinity risks and lack of effective electrical protections add up to an increased risk of ignition.
Fire protection (1995)
This code sets out the fire prevention and protection rules and procedures to be followed in order to ensure primarily the safety and well-being of anyone and to protect the property on CERN's premises. It lays down the procedures to be observed concerning the construction, alteration and use of buildings or installations, the safety standards for furniture and contents of buildings and the procedure applicable to the fire permit for work with "hot" tools. It gives information on fire-detection and extinguishing appliances and provides essential information in the event of a fire.

Office buildings fire protection
This document provides a summary of the fire Safety requirements applicable to "office buildings" at CERN. These requirements are based on the French and Swiss legislation and standards.
- SG FS-0-0-2
Smoke extraction systems
To provide guidance for compliance with Fire Safety requirements for smoke extraction systems installed in surface buildings located in French territory.
Safety Forms (SF)
The FIRE PERMIT is drawn up in order to prevent the risk of fire or explosion created by ‘hot’ tools (mainly welding torches and electric arc-welding equipment). For every item of work of this kind, the person who execute it must be an authorised operator and must be in possession of a properly completed and signed FIRE PERMIT. It does not apply to work done at permanent work-stations at CERN. CERN's endorsement does not in any way release the operator from his responsibilities. Also see code E.

Evacuation procedure and principles for CERN sites on French territory
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.
