Safety rules for the domain of Chemical, Cryogenic and Biological Safety

Safety rules according to the new classification

SR-C - Chemical agents en fr
The purpose of this Safety Regulation is to set out the minimum requirements for the protection of persons from risks to their occupational health and safety arising, or likely to arise, from the effects of hazardous chemical agents that are present at the workplace or used in any CERN activity.
This Safety Regulation applies to all CERN activities involving hazardous chemical agents.
This Safety Regulation does not apply to CERN activities:

• involving chemical agents which are hazardous solely by virtue of their radioactive properties, or solely because they are at a high or low temperature or a high pressure (which are dealt with in other Safety Regulations);
• involving any of the hazardous chemical agents: 2-naphtylamine and its salts, 4-aminodiphenyl and its salts, benzidine and its salts, 4-nitrodiphenyl, as defined in Annex III of Council Directive 98/24/EC;
• involving chemical agents which only meet the criteria for classification as dangerous for the environment (which are dealt with in another Safety Regulation).

GSI-C1 - Prevention and protection measures en fr

It sets out the minimum requirements which prevention and protection measures must satisfy in order to ensure the protection of persons from risks to their occupational health and safety arising, or likely to arise, from the effects of hazardous chemical agents that are present at the workplace or used in any CERN activity.

GSI-C2 - Explosive atmospheres en fr
This General Safety Instruction applies to all CERN activities involving hazardous chemical agents where explosive atmospheres are present or may be present. It sets out the minimum requirements to ensure the protection of persons from risks to their occupational health and safety arising, or likely to arise, from explosive atmospheres.

GSI-C3 - Monitoring of exposure to hazardous chemical agents in workplace atmospheres en fr

Until the implementation of the provisions of this Safety Regulation and General Safety Instructions, the corresponding provisions of Safety Code "Chemical" (Safety Code B) and Safety Code "Flammable gas" (Safety Code G) shall continue to apply.

Safety rules according to the old classification

Safety Instruction IS 43 - Asbestos - Dangers and precautions (2003) en fr
The purpose of this safety instruction is to remind the CERN personnel of the safety instructions prohibiting the use of asbestos, of those concerning the management of asbestos in situ and those governing activities entailing a risk of exposure to asbestos.

Safety Instruction IS 47 - The use of cryogenics fluids (1998) en fr
The cooling and operation of superconducting RF cavities and magnet systems for particle accelerators and magnets for detectors requires large quantities of cryogenic fluids. These fluids may generate health hazards for cryogenic personnel (asphyxiation, burns, etc.). A number of precautions or measures must be taken to prevent accidents and injuries, for instance: protective clothing, vent lines, alarm and shutdown systems or pressure relief devices.

In the event of any contradiction between Safety rules established according to the classification of SAPOCO 42, version February 2003, and Safety rules established according to the classification of SAPOCO, rev. November 2006, the latter shall prevail.

Safety Guidelines and Forms for the domain of Chemical, Cryogenic and Biological Safety

Safety Guideline C-0-0-1 - Identification of hazardous chemical agents en
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.

Safety Guideline C-0-0-2 - Chemical risk assessment (Inhalation) en
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.

Safety Guideline C-0-0-3 - Lead en
This Safety Guideline is intended to establish guidelines for the safe use and handling of lead and its compounds at CERN, and to give advice where lead may be present at CERN.

Safety Guideline C-1-0-1 - Storage of hazardous chemical agents en
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.

Safety Guideline C-1-0-2 - Chemical protective gloves en
This Safety Guideline is intended to indicate the chemical protection gloves available in the CERN stores and to provide advice on their choice, use and maintenance.

Safety Guideline C-2-0-1 - Explosion protection measures en
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.

Safety Guideline C-2-0-2 - Identification and prevention of explosion hazards en
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.
