A Material Safety Data Sheet should be structured in order to present the information of chemical hazard in clear form and must include relevant information about the following topics: Section 1: Chemical Product and Company Identification Names the material and relates the MSDS with the label and shipping documents. Must also have a mailing address and telephone number for the manufacturer or distributor. Section 2: Composition, Information on Ingredients: Identifies the hazardous components of the material. If non-hazardous ingredients are listed, they should be listed separately. Chemical Abstract Service (CAS) and UN transport code numbers should be included. If the identity of any ingredient is claimed to be a trade secret, it should be so indicated in this section. Section 3: Hazards Identification: Describes the material's appearance, odour, and health, physical, and environmental hazards that may be of concern for emergency response personnel. Section 4: First Aid Measures: This section should include emergency and first aid procedures. It should be in layman's language, easy to understand, and procedures for each potential route of exposure should be included. A "Notes to Physicians" subsection should be included if such information is available. Section 5: Fire Fighting Measures: This section should describe fire and explosive properties of the material, extinguishing media to be used, and fire-fighting instructions. It applies to anyone who may be in the area of the fire. Section 6: Accidental Release Measures: This section should have information needed to prevent or minimize adverse effects on employees, neighbours, property, and the environment, including waterways. It is intended for emergency response personnel. Section 7: Handling and Storage: This section provides guidelines for minimizing any potential hazards from storing the material. It should include information to minimize handling when appropriate, and conditions such as temperature, inert atmosphere, and conditions to avoid. Section 8: Exposure Controls, Personal Protection: Discusses the degree of engineering control that may be needed when handling the material, and the personal protective equipment that should be used if there is a potential for exposure above the regulatory or suggested limits. Section 9: Physical and Chemical Properties: These properties should be included to assist users to determine proper handling and storage. Appearance, odour, physical state (liquid, solid, gas), pH, vapour pressure and density, melting and freezing point, solubility, and specific gravity should be included. Additional properties may be included if they are useful. Section 10: Stability and Reactivity: This section should describe conditions that may result in a potentially hazardous reaction, such as evolution of hazardous gases, production of heat, or other hazardous conditions. Section 11: Toxicological Information: This section should include any known information resulting from animal testing or human experience on the toxicity of the material. Also included would be information on its potential for causing cancer. Data should be included for acute, subchronic, and chronic exposures, if available. Section 12: Ecological Information: This section should list impacts to the environment that may occur if the material is released to the environment, or in evaluating waste treatment practices. Section 13: Disposal Considerations: This section is intended to provide guidance to environmental and other technical people responsible for waste management for the product. Section 14: Transport Information: This section should provide information concerning classification for shipping the material. The information of this transport which need to be considered include: (1) Regulation and control (2) Classification and codes (3) Packing and labeling (4) Transport containers (5) Hazard (6) Basic emergency planning The transport of chemicals is an international activity and international codes assume a crucial role. In a MSDS the main international code of shipping should be included: ONU number, UN transport code, ADR, European Road Carriage Agreement, RID, International Rail Carriage Regulations, IMDG, International Maritime Dangerous Goods
