Generally, no account needs to be taken of substances if they are present in following amounts, unless another lower limit has been specifically given:  less than 0.1% by weight for substances classified as very toxic T+, or toxic T  less than 1% for substances classified as harmful Xn, corrosive C, irritant Xi,  Information such as "non-toxic", "not harmful" should not be used in the labels. The pictorial symbol indicating danger is drawn in black and the background colour should be orange. The dimensions of the label:

International, regional, and national classification and labelling systems are already established and tested in practice.  The United Nations Recommendations on the Transport of Dangerous Goods is widely recognized and used among the UN member states.  An example of a system that has been designed for use in several countries is the classification and labelling system of the European Communities (EC).  Several functioning national systems, such as those of Canada and USA, may also be used as models for national systems.  This guide could be used as training material or at places of work when individual labels are checked or prepared using the data on chemical substances listed in Annex 4. It may also serve as reference material, or as a manual, providing basic safety information on these substances. This guide describes the labelling system used in the countries of the European Union (EU) as an example and the United Nations Recommendations on the Transport of Dangerous Goods is also briefly presented. This document consists of:  EU symbols and indications of danger  EU standard risk phrases (R-phrases)  EU standard safety phrases (S-phrases)  list of dangerous substances with the classification and labelling requirements  IARC list of cancer causing substances, carcinogens  list of chemicals with properties potential to cause major hazard  list of some substances and products which are subject to a ban or restrictions in EU countries  UN list of hazard classes for transport of dangerous goods  UN symbols for transport of dangerous goods  2. Identification and Classification The objective is to identify the hazardous properties of chemicals which may constitute a risk during normal handling or use, risks to health, property or the environment. The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage. These have their own specifications and requirements for labelling. 3. What is a hazardous chemical ? The following properties contribute to risk to health resulting from acute, repeated or prolonged exposure:  very toxic or toxic  harmful  corrosive  irritant  cancer causing  hazards to reproduction  can cause non-heritable birth defects  sensitizing  Fire and explosion hazards may be classified as follows  explosive  oxidizing  extremely flammable  highly flammable  flammable  The following properties present a hazard to the environment and are:  toxic to living organisms  persistent in the environment  bioaccumulative  Also substances and preparations that cannot be classified by using the above system may be regarded as dangerous if they have properties which are hazardous to health, to living organisms or if they can damage property. 4. How to pass on the information to users? All chemicals, both substances and preparations, should have a clear marking to indicate their identity. The packages and containers of dangerous substances and preparations should, in addition to marking only, to have a label with required information. The label should draw attention to the inherent danger to persons handling or using the chemical. Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5. Where to find information about hazardous chemicals? The chemical supplier, manufacturer or importer, should be able to provide detailed information and a Safety Data Sheet. In certain countries, such as those of the EU, the manufacturer or importer has the obligation to find and give adequate information about a chemical for assessment of the health and environmental hazards of his chemical for handling and for its labelling. Safety data sheets have been prepared on many dangerous substances and preparations by manufacturers. These should go together with the product to the occupational user. The information in these is not always validated or checked. On pure substances International Chemical Safety Cards are available. These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used.

The hazard classification and labelling process is an essential tool for establishing an effective information transfer so that the degree of the hazard the chemical represents for man and the environment can be recognized, the correct preventive actions be chosen, and safe use achieved. The International Labour Organization (ILO) has adopted the Convention No. 170 and Recommendation No. 177 on `Safety in the use of chemicals at work' in 1990. International, regional, and national classification and labelling systems are already established and tested in practice.  The United Nations Recommendations on the Transport of Dangerous Goods is widely recognized and used among the UN member states.  An example of a system that has been designed for use in several countries is the classification and labelling system of the European Communities (EC).  Several functioning national systems, such as those of Canada and USA, may also be used as models for national systems.  This guide could be used as training material or at places of work when individual labels are checked or prepared using the data on chemical substances listed in Annex 4. It may also serve as reference material, or as a manual, providing basic safety information on these substances. This guide describes the labelling system used in the countries of the European Union (EU) as an example and the United Nations Recommendations on the Transport of Dangerous Goods is also briefly presented. This document consists of:  EU symbols and indications of danger  EU standard risk phrases (R-phrases)  EU standard safety phrases (S-phrases)  list of dangerous substances with the classification and labelling requirements  IARC list of cancer causing substances, carcinogens  list of chemicals with properties potential to cause major hazard  list of some substances and products which are subject to a ban or restrictions in EU countries  UN list of hazard classes for transport of dangerous goods  UN symbols for transport of dangerous goods  2. Identification and Classification The objective is to identify the hazardous properties of chemicals which may constitute a risk during normal handling or use, risks to health, property or the environment. The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage. These have their own specifications and requirements for labelling. 3. What is a hazardous chemical ? The following properties contribute to risk to health resulting from acute, repeated or prolonged exposure:  very toxic or toxic  harmful  corrosive  irritant  cancer causing  hazards to reproduction  can cause non-heritable birth defects  sensitizing  Fire and explosion hazards may be classified as follows  explosive  oxidizing  extremely flammable  highly flammable  flammable  The following properties present a hazard to the environment and are:  toxic to living organisms  persistent in the environment  bioaccumulative  Also substances and preparations that cannot be classified by using the above system may be regarded as dangerous if they have properties which are hazardous to health, to living organisms or if they can damage property. 4. How to pass on the information to users? All chemicals, both substances and preparations, should have a clear marking to indicate their identity. The packages and containers of dangerous substances and preparations should, in addition to marking only, to have a label with required information. The label should draw attention to the inherent danger to persons handling or using the chemical. Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5. Where to find information about hazardous chemicals? The chemical supplier, manufacturer or importer, should be able to provide detailed information and a Safety Data Sheet. In certain countries, such as those of the EU, the manufacturer or importer has the obligation to find and give adequate information about a chemical for assessment of the health and environmental hazards of his chemical for handling and for its labelling. Safety data sheets have been prepared on many dangerous substances and preparations by manufacturers. These should go together with the product to the occupational user. The information in these is not always validated or checked. On pure substances International Chemical Safety Cards are available. These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used. The explanation of the letter symbols appearing in the attached lists are given below. Each letter symbol refers to a danger symbol or pictogram in Annex 1:

Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5. Where to find information about hazardous chemicals? The chemical supplier, manufacturer or importer, should be able to provide detailed information and a Safety Data Sheet. In certain countries, such as those of the EU, the manufacturer or importer has the obligation to find and give adequate information about a chemical for assessment of the health and environmental hazards of his chemical for handling and for its labelling. Safety data sheets have been prepared on many dangerous substances and preparations by manufacturers. These should go together with the product to the occupational user. The information in these is not always validated or checked. On pure substances International Chemical Safety Cards are available. These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used. The explanation of the letter symbols appearing in the attached lists are given below. Each letter symbol refers to a danger symbol or pictogram in Annex 1:

The key to have the symbol picture is in Annex 1. The key to have a sentence in words is for the risk phrases in Annex 2. and for the safety phrases in Annex 3.

The first and most essential step leading to safe use of chemicals is to know their identity, to their hazards to health and the environment and the means to control them. This knowledge should be available with reasonable effort and cost. Furthermore, this inherently complex knowledge must be organized in such a way that essential information on the hazards and corresponding protective measures can be identified and conveyed to the user in a form that is easy to understand. The hazard classification and labelling process is an essential tool for establishing an effective information transfer so that the degree of the hazard the chemical represents for man and the environment can be recognized, the correct preventive actions be chosen, and safe use achieved. The International Labour Organization (ILO) has adopted the Convention No. 170 and Recommendation No. 177 on `Safety in the use of chemicals at work' in 1990. International, regional, and national classification and labelling systems are already established and tested in practice.  The United Nations Recommendations on the Transport of Dangerous Goods is widely recognized and used among the UN member states.  An example of a system that has been designed for use in several countries is the classification and labelling system of the European Communities (EC).  Several functioning national systems, such as those of Canada and USA, may also be used as models for national systems.  This guide could be used as training material or at places of work when individual labels are checked or prepared using the data on chemical substances listed in Annex 4. It may also serve as reference material, or as a manual, providing basic safety information on these substances. This guide describes the labelling system used in the countries of the European Union (EU) as an example and the United Nations Recommendations on the Transport of Dangerous Goods is also briefly presented. This document consists of:  EU symbols and indications of danger  EU standard risk phrases (R-phrases)  EU standard safety phrases (S-phrases)  list of dangerous substances with the classification and labelling requirements  IARC list of cancer causing substances, carcinogens  list of chemicals with properties potential to cause major hazard  list of some substances and products which are subject to a ban or restrictions in EU countries  UN list of hazard classes for transport of dangerous goods  UN symbols for transport of dangerous goods  2. Identification and Classification The objective is to identify the hazardous properties of chemicals which may constitute a risk during normal handling or use, risks to health, property or the environment. The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage. These have their own specifications and requirements for labelling. 3. What is a hazardous chemical ? The following properties contribute to risk to health resulting from acute, repeated or prolonged exposure:  very toxic or toxic  harmful  corrosive  irritant  cancer causing  hazards to reproduction  can cause non-heritable birth defects  sensitizing  Fire and explosion hazards may be classified as follows  explosive  oxidizing  extremely flammable  highly flammable  flammable  The following properties present a hazard to the environment and are:  toxic to living organisms  persistent in the environment  bioaccumulative  Also substances and preparations that cannot be classified by using the above system may be regarded as dangerous if they have properties which are hazardous to health, to living organisms or if they can damage property. 4. How to pass on the information to users? All chemicals, both substances and preparations, should have a clear marking to indicate their identity. The packages and containers of dangerous substances and preparations should, in addition to marking only, to have a label with required information. The label should draw attention to the inherent danger to persons handling or using the chemical. Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5.

This document consists of:  EU symbols and indications of danger  EU standard risk phrases (R-phrases)  EU standard safety phrases (S-phrases)  list of dangerous substances with the classification and labelling requirements  IARC list of cancer causing substances, carcinogens  list of chemicals with properties potential to cause major hazard  list of some substances and products which are subject to a ban or restrictions in EU countries  UN list of hazard classes for transport of dangerous goods  UN symbols for transport of dangerous goods  2. Identification and Classification The objective is to identify the hazardous properties of chemicals which may constitute a risk during normal handling or use, risks to health, property or the environment. The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage. These have their own specifications and requirements for labelling. 3. What is a hazardous chemical ? The following properties contribute to risk to health resulting from acute, repeated or prolonged exposure:  very toxic or toxic  harmful  corrosive  irritant  cancer causing  hazards to reproduction  can cause non-heritable birth defects  sensitizing  Fire and explosion hazards may be classified as follows  explosive  oxidizing  extremely flammable  highly flammable  flammable  The following properties present a hazard to the environment and are:  toxic to living organisms  persistent in the environment  bioaccumulative  Also substances and preparations that cannot be classified by using the above system may be regarded as dangerous if they have properties which are hazardous to health, to living organisms or if they can damage property. 4. How to pass on the information to users? All chemicals, both substances and preparations, should have a clear marking to indicate their identity. The packages and containers of dangerous substances and preparations should, in addition to marking only, to have a label with required information. The label should draw attention to the inherent danger to persons handling or using the chemical. Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5. Where to find information about hazardous chemicals? The chemical supplier, manufacturer or importer, should be able to provide detailed information and a Safety Data Sheet. In certain countries, such as those of the EU, the manufacturer or importer has the obligation to find and give adequate information about a chemical for assessment of the health and environmental hazards of his chemical for handling and for its labelling. Safety data sheets have been prepared on many dangerous substances and preparations by manufacturers. These should go together with the product to the occupational user. The information in these is not always validated or checked. On pure substances International Chemical Safety Cards are available. These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used. The explanation of the letter symbols appearing in the attached lists are given below. Each letter symbol refers to a danger symbol or pictogram in Annex 1:

The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage.

These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used. The explanation of the letter symbols appearing in the attached lists are given below. Each letter symbol refers to a danger symbol or pictogram in Annex 1:

The International Labour Organization (ILO) has adopted the Convention No. 170 and Recommendation No. 177 on `Safety in the use of chemicals at work' in 1990. International, regional, and national classification and labelling systems are already established and tested in practice.  The United Nations Recommendations on the Transport of Dangerous Goods is widely recognized and used among the UN member states.  An example of a system that has been designed for use in several countries is the classification and labelling system of the European Communities (EC).  Several functioning national systems, such as those of Canada and USA, may also be used as models for national systems.  This guide could be used as training material or at places of work when individual labels are checked or prepared using the data on chemical substances listed in Annex 4. It may also serve as reference material, or as a manual, providing basic safety information on these substances. This guide describes the labelling system used in the countries of the European Union (EU) as an example and the United Nations Recommendations on the Transport of Dangerous Goods is also briefly presented. This document consists of:  EU symbols and indications of danger  EU standard risk phrases (R-phrases)  EU standard safety phrases (S-phrases)  list of dangerous substances with the classification and labelling requirements  IARC list of cancer causing substances, carcinogens  list of chemicals with properties potential to cause major hazard  list of some substances and products which are subject to a ban or restrictions in EU countries  UN list of hazard classes for transport of dangerous goods  UN symbols for transport of dangerous goods  2. Identification and Classification The objective is to identify the hazardous properties of chemicals which may constitute a risk during normal handling or use, risks to health, property or the environment. The user of the chemicals is also to be introduced to the hazards they present and given the basic information, in a suitable manner, such as using a properly made label. In this document one component chemical is called a substance, a mixture composed of two or more substances is called a preparation. The hazards of preparations can be assessed using the information on hazards of their component substances. (See example 2.) For classification purposes the degree of hazard depends not only on the properties of a dangerous substance but also on the level of exposure. This refers to the concentration of hazardous components in the mixtures. In order to assess a preparation it is essential to know also the quantities of its hazardous minor components. The EU classification and labelling system used here as an example can be applied to dangerous substances and preparations. However, this system should not be applied to medical or veterinary products, cosmetics, munitions or explosives, pesticides specified elsewhere, waste and foodstuffs or animal feedstuffs in the finished stage. These have their own specifications and requirements for labelling. 3. What is a hazardous chemical ? The following properties contribute to risk to health resulting from acute, repeated or prolonged exposure:  very toxic or toxic  harmful  corrosive  irritant  cancer causing  hazards to reproduction  can cause non-heritable birth defects  sensitizing  Fire and explosion hazards may be classified as follows  explosive  oxidizing  extremely flammable  highly flammable  flammable  The following properties present a hazard to the environment and are:  toxic to living organisms  persistent in the environment  bioaccumulative  Also substances and preparations that cannot be classified by using the above system may be regarded as dangerous if they have properties which are hazardous to health, to living organisms or if they can damage property. 4. How to pass on the information to users? All chemicals, both substances and preparations, should have a clear marking to indicate their identity. The packages and containers of dangerous substances and preparations should, in addition to marking only, to have a label with required information. The label should draw attention to the inherent danger to persons handling or using the chemical. Symbols and pictograms have been established for each hazard category listed above. The symbol forms an integral part of the label and gives an immediate idea of the types of hazards that the substance or the preparation may cause. (Annex 1) To specify the type of danger pertinent standard risk phrases should also be included in the label. (Annex 2) Advice on the precautions necessary in the handling of chemicals are given with standard safety phrases also included in the label. (Annex 3) 5. Where to find information about hazardous chemicals? The chemical supplier, manufacturer or importer, should be able to provide detailed information and a Safety Data Sheet. In certain countries, such as those of the EU, the manufacturer or importer has the obligation to find and give adequate information about a chemical for assessment of the health and environmental hazards of his chemical for handling and for its labelling. Safety data sheets have been prepared on many dangerous substances and preparations by manufacturers. These should go together with the product to the occupational user. The information in these is not always validated or checked. On pure substances International Chemical Safety Cards are available. These contain validated basic information, which may be used also for preparing safety data sheets on chemical preparations or products. Lists of classified chemicals exist in several national legislations and regulations which provide information on local requirements in the handling of dangerous chemicals. The information for classification, and labels, may be obtained from tests, from literature, from practical experience and from information requirements by international rules on the transport of dangerous substances and wastes. Some sources of information are listed in the bibliography. 6. How to classify for a label? The label is the basic tool to keep the user informed on the classification and the most important safety precautions. This information must be given if the preparation contains at least one substance classified as dangerous to man or the environment or if the preparation is otherwise regarded as dangerous, e.g. flammable, explosive. (Annex 4) In EU countries the label must clearly show  the trade name  the name and the address, including telephone number, of the manufacturer, the importer or the distributor  the chemical name of the substance (in the case of a preparation, the chemical names of the hazardous components)  danger symbols  risk phrases (R-phrases)  safety phrases (S-phrases)  the quantity of the contents of the package or container  The labels should be in the national, official language(s). The label should show the chemical names of substances that are primarily responsible for the hazards. As a general rule a maximum of four chemical names on the label should be sufficient. In some cases, more than four names may be necessary; for example all cancer causing substances in the preparation must be identified and the corresponding R- and S-phrases presented on the label. If the preparation contains one or more of the substances requiring the following R-phrases, both the name of the substance and the R-phrase should be mentioned in the label:  R39, R40, R42, R43, R42/43, R45, R46, R47, R48, R49, R60, R61, R62, R63, R64  As a general rule a maximum of four R-phrases and four S- phrases should suffice to describe the risks and to formulate the most appropriate safety advice. Symbols showing the most serious hazards should be chosen where more than one danger symbol has to be assigned. As a general rule a maximum of two danger symbols are used. The explanation of the letter symbols appearing in the attached lists are given below. Each letter symbol refers to a danger symbol or pictogram in Annex 1:
