What is CLP?
The CLP Regulation, or Classification, Labeling and Packaging of Substances and Mixtures, is a European Union (EU) regulation that standardizes the classification, labeling, and packaging of chemicals. It aims to ensure a high level of protection for human Health and the Environment by providing clear and consistent information about the hazards associated with chemicals.
Key Features of CLP
- Harmonized Classification: CLP establishes a harmonized system for classifying chemicals based on their physical, health, and environmental hazards. This ensures consistent classification across the EU.
- Standardized Labeling: The regulation mandates specific labeling requirements for chemicals, including hazard pictograms, signal words, hazard statements, and precautionary statements. These labels provide clear and concise information about the risks associated with the chemical.
- Safety Data Sheets (SDS): CLP requires the provision of Safety Data Sheets (SDS) for all chemicals. SDSs contain detailed information about the chemical, including its properties, hazards, safe handling procedures, and emergency response measures.
- Pre-emptive Approach: CLP adopts a pre-emptive approach to Chemical Safety, requiring manufacturers and importers to classify, label, and package chemicals before they are placed on the market.
Classification of Chemicals under CLP
CLP classifies chemicals based on their potential hazards into 16 hazard classes:
| Hazard Class | Description |
|---|---|
| Physical Hazards | |
| Explosive | Substances or mixtures that can explode under specific conditions. |
| Flammable liquids | Liquids that easily ignite and burn. |
| Flammable solids | Solids that easily ignite and burn. |
| Flammable gases | Gases that easily ignite and burn. |
| Oxidizing gases | Gases that can cause or contribute to combustion. |
| Oxidizing liquids | Liquids that can cause or contribute to combustion. |
| Oxidizing solids | Solids that can cause or contribute to combustion. |
| Self-reactive substances and mixtures | Substances or mixtures that can undergo a dangerous exothermic reaction. |
| Pyrophoric liquids | Liquids that ignite spontaneously in air. |
| Pyrophoric solids | Solids that ignite spontaneously in air. |
| Self-heating substances and mixtures | Substances or mixtures that can heat up spontaneously. |
| Substances and mixtures that in contact with water emit flammable gases | Substances or mixtures that react with water to produce flammable gases. |
| Health Hazards | |
| Acute toxicity | Substances or mixtures that can cause immediate or short-term health effects. |
| Skin corrosion/irritation | Substances or mixtures that can cause skin damage. |
| Serious eye damage/eye irritation | Substances or mixtures that can cause eye damage. |
| Respiratory sensitization | Substances or mixtures that can cause allergic reactions in the Respiratory System. |
| Skin sensitization | Substances or mixtures that can cause allergic reactions on the skin. |
| Germ cell mutagenicity | Substances or mixtures that can damage genetic material. |
| Carcinogenicity | Substances or mixtures that can cause cancer. |
| Reproductive toxicity | Substances or mixtures that can affect fertility or development. |
| Specific target organ toxicity – single exposure | Substances or mixtures that can cause damage to specific organs after a single exposure. |
| Specific target organ toxicity – repeated exposure | Substances or mixtures that can cause damage to specific organs after repeated exposure. |
| Aspiration hazard | Substances or mixtures that can cause lung damage if aspirated. |
| Environmental Hazards | |
| Hazardous to the aquatic environment – acute | Substances or mixtures that can cause short-term harm to aquatic organisms. |
| Hazardous to the aquatic environment – chronic | Substances or mixtures that can cause long-term harm to aquatic organisms. |
Labeling Requirements under CLP
CLP requires specific labeling Elements for chemicals, including:
- Hazard Pictograms: Standardized pictograms representing the different hazard classes.
- Signal Words: “Danger” or “Warning,” indicating the severity of the hazard.
- Hazard Statements: Phrases describing the specific hazards associated with the chemical.
- Precautionary Statements: Instructions on how to safely handle, store, and use the chemical.
- Supplementary Information: Additional information about the chemical, such as its chemical name, CAS number, and supplier information.
Example of a CLP Label
| Pictogram | Signal Word | Hazard Statement | Precautionary Statement |
|---|---|---|---|
| Flammable liquid | Danger | H225: Highly flammable liquid and vapor. | P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. |
Safety Data Sheets (SDS)
SDSs are comprehensive documents that provide detailed information about the chemical, including:
- Identification: Chemical name, CAS number, supplier information.
- Hazard Identification: Classification of the chemical according to CLP.
- Composition/Information on Ingredients: Chemical composition of the mixture.
- First-Aid Measures: Instructions on how to provide first aid in case of exposure.
- Fire-Fighting Measures: Information on how to extinguish fires involving the chemical.
- Accidental Release Measures: Procedures for handling accidental spills or releases.
- Handling and Storage: Safe handling and storage practices.
- Exposure Controls/Personal Protection: Measures to protect workers from exposure to the chemical.
- Physical and Chemical Properties: Physical and chemical characteristics of the chemical.
- Stability and Reactivity: Information on the chemical’s stability and reactivity.
- Toxicological Information: Health effects of the chemical.
- Ecological Information: Environmental effects of the chemical.
- Disposal Considerations: Safe disposal methods for the chemical.
- Transport Information: Information on the safe transportation of the chemical.
- Regulatory Information: Relevant regulatory information.
- Other Information: Additional information about the chemical.
Benefits of CLP
