CERN Accelerating science

This Safety Guideline is intended to provide practical advice for the identification of hazardous chemical agents. Safety Regulation SR-C, Chemical agents requires the identification to be followed-up with an assessment of the risks and the adoption of suitable prevention and protection measures. All relevant information must be recorded in the Safety Form C-0-0-1, Chemical risk assessment.

In accordance with Safety Regulation SR-C, Chemical agents, this Safety Guideline is intended to assess the level of risk from inhalation and determine the control measures appropriate for a given activity involving hazardous chemical agents. It is a simplified assessment method which can be used together with the requirements for the monitoring of exposure to hazardous chemical agents in workplace atmospheres given in General Safety Instruction GSI-C3, Monitoring of exposure to hazardous chemical agents in workplace atmospheres.

This Safety Guideline provides guidance for the handling and use of lead.
Reminder: As lead is a hazardous substance, the general prevention principles (Substitution, Technical Protection measures, Organisational measures, Personal protective measures - STOP principle) apply (cf. SR-C).

This Safety Guideline is intended to provide practical advice concerning the steps to be taken if you use hazardous substances which have been registered under REACH.

This Safety Guideline is aimed at those people who, in the course of their duties, handle nanomaterials or those who are responsible for putting in place control measures for activities involving nanomaterials.

In accordance with General Safety Instruction GSI-C1, Prevention and Protection Measures, this Safety Guideline is intended to give directives concerning the storage of hazardous chemical agents. Chemical agents must be stored either in a central storage area or in the chemical laboratory or workshop. Workbenches or fume cupboards must not be used for the storage of chemical agents, but rather for placing chemical agents which are in use. At the end of the working day chemical agents must be returned to storage, either to a cabinet in the laboratory or else to the central storage area.

This Safety Guideline is intended to indicate the chemical protective gloves available in the CERN stores and to provide advice on their choice, use and maintenance.

This Safety Guideline is intended to provide users of LEV systems with practical advice on how to ensure their system is effective as a control measure for preventing exposure.

This Safety Guideline is intended for use with all activities which involve flammable substances and which may give rise to explosive atmospheres and so explosion hazards. It provides practical advice for the implementation of protection measures.

This Safety Guideline is intended for use with all activities involving flammable substances which may give rise to explosive atmospheres and hence explosion hazards. It describes the method to be used for the assessment which must be recorded using the Safety Form C-2-0-1, Explosion Risk Assessment.

This Safety Guideline is intended to provide FGSOs with practical advice on how to perform and record the classification of hazardous areas.

This Safety Guideline is intended to set out advice relating to the design, installation and maintenance of Safety lighting installations in buildings (or institutions) not receiving public.

Safety Guideline under revision. For any questions please contact the HSE Unit: safety-rules.secretariat@cern.ch.

To provide guidance for compliance with Fire Safety requirements for smoke extraction systems installed in surface buildings located in French territory.

This Safety Guideline provides guidance as to the implementation of Safety Rule
SSI-FS-2-1 “Fire Safety and Radiation Resistance Requirements for Cables” (hereafter “SSI-FS-2-1”) in particular with regard to the certification and selection of Cable materials.

In accordance with General Safety Instruction GSI-M-4 Cryogenic equipment, this Safety Guideline is intended to provide advice on the safe use of cryogenic equipment and its conformity. This Safety Guideline is aimed at those people who, in the course of their duties, work with cryogenic equipment or those who are responsible for putting in place control measures for activities involving cryogenics.

This Safety Guideline provides guidance for the implementation of General Safety Instruction GSI-NIR-1 “Exposure to Static Magnetic Fields” (hereafter “GSI-NIR-1”). Static Magnetic Fields (SMF) are electromagnetic fields with a fundamental frequency (c.f. Annex 2 - section 6.2) between 0 and 1 Hz.

The purpose of this Safety Guideline 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.

This Safety Guide is a help for tender writers. It makes it possible to integrate aspects related to safety into the tender documents.
This guide is based on a summary of the responses provided by the HSE unit when verifying over 800 tenders.
The application of this guide does not relieve the writer from contacting HSE specialists as early as possible in the writing process and sending calls or requests for offers to the HSE unit.
This Safety Guide cancels and replaces the Safety Guide GS-0-0-1 

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.

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 .

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.

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).

This Safety Guidelline sets out the requirements to be met for any work on the roof. For specific cases or in case of any questions, please contact the HSE Unit (safety.info@cern.ch)
