Chemical Safety (C)

SR-C – Chemical Agents

The purpose of this Safety Regulation is to define the minimum Safety requirements for the protection of persons from risks to their 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.

It applies to any CERN activity involving hazardous chemical agents.

GSI-C-1 – Prevention and protection measures

The purpose of this General Safety Instruction is to define the minimum Safety requirements which prevention and protection measures must satisfy in order to ensure the protection of persons from risks to their 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.

It applies to any CERN activity involving hazardous chemical agents.

GSI-C-2 – Explosive atmospheres

The purpose of this General Safety Instruction is to define the minimum Safety requirements to ensure the protection of persons from risks to their occupational health and safety arising, or likely to arise, from explosive atmospheres.

It applies to all CERN activities involving hazardous chemical agents where explosive atmospheres are present or may be present.

GSI-C-3 – Monitoring of exposure to hazardous chemical agents in workplace atmospheres

The purpose of this General Safety Instruction is to define the minimum Safety requirements regarding the monitoring of exposure to hazardous chemical agents in workplace atmospheres.

It applies to all CERN activities where hazardous chemical agents are present or are likely to be present in workplace atmospheres. 

IS 42 – Compressed gas bottles (1995)

Safety rules for the transport, use and storing of cylinders to avoid fire or explosion hazards.

IS 43 – Asbestos – Dangers and precautions (2003)

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.

IS 49 – Avoiding chemical pollution of water (2002)

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.

SG C-0-0-1 – Identification of hazardous chemical agents

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.

SG C-0-0-2 – Chemical risk assessment (Inhalation)

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.

SG C-0-0-3 – Safe Handling and Storage of Lead at CERN

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).

SG C-0-0-4 – REACH

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.

SG C-0-0-5 – Safe handling and disposal of nanomaterials

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.

SG C-0-0-6 – Beryllium

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

SG C-1-0-1 – Storage of hazardous chemical agents

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.

SG C-1-0-2 – Chemical protective gloves

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.

SG C-1-0-3 – Practical guide for users of local exhaust ventilation (LEV) systems

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.

SG C-2-0-1 – Explosion protection measures

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.

SG C-2-0-2 – Identification and prevention of explosion hazards

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.

SG C-2-0-3 – Practical guide for classification of hazardous areas

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