Section 12 — Ecological information provides information to evaluate the environmental impact of the chemical s if it were released to the environment. Section 13 — Disposal considerations provides guidance on proper disposal practices, recycling or reclamation of the chemical s or its container, and safe handling practices. Section 14 — Transport information includes guidance on classification information for shipping and transporting of hazardous chemical s by road, air, rail, or sea.
Section 15 — Regulatory information identifies the safety, health, and environmental regulations specific for the product that is not indicated anywhere else on the SDS. Section 16 — Other information indicates when the SDS was prepared or when the last known revision was made. The SDS may also state where the changes have been made to the previous version.
Who develops or prepares the MSDS? The manufacturer of the product is the one who prepares the MSDS for the product. What does an MSDS contain? A Material Safety Data Sheet MSDS is a document that contains information on the potential hazards health, fire, reactivity and environmental and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. What are the 9 categories of MSDS?
The MSDS contains important information about chemicals and their effects, proper handling and other areas of concern. Manufacturer's Contact Information. Hazardous Ingredients. Physical Data. Reactivity Data. Information required in this section includes: Necessary first-aid instructions by relevant routes of exposure inhalation, skin and eye contact, and ingestion. Description of the most important symptoms or effects, and any symptoms tha are acute or delayed.
Recommendations for immediate medical care and special treatment needs when necessary. Section 5: Fire-Fighting Measures. Information required in this section includes: Recommendations of suitable extinguishing equipment, and information about extinguishing equipment that is not appropriate for a particular situation.
Advice on specific hazards that develop from the chemical during a fire, such as any hazardous byproducts created when the chemical burns. Recommendations of special protective equipment or precautions for firefighters. Section 6: Accidental Release Measures. Emergency procedures, including instructions for evacuations, consulting experts when needed, and appropriate protective clothing.
Methods and materials used for containment e. Clean up procedures e. Section 7: Handling and Storage. Information required in this section includes: Precautions for safe handling, including recommendations for handling incompatible chemicals, minimizing release into the environment, and providing advice on general hygiene practices e.
Recommendations on the conditions for safe storage, including any incompatibilities. Provide advice on specific storage requirements e. Appropriate engineering controls i. Recommendations for personal protective measures to prevent illness or injury from exposure, such as personal protective equipment PPE e.
Any such special requirements for PPE, protective clothing or respiratory protection e. Section 9: Physical and Chemical Properties. The minimum required information required in this section includes: Appearance physical state, color, etc. Section Stability and Reactivity. Information required in this section includes: Reactivity Description of the specific test data for the chemical s.
This data can be for a class or family of the chemical if the data adequately represents the anticipated hazard of the chemical s , where available. Chemical Stability Indication of whether the chemical is stable or unstable under normal ambient temperature and conditions while in storage and being handled. Description of any stabilizers that may be needed to maintain chemical stability.
Indication of any safety issues that may arise should the product change in physical appearance. Other Indication of the possibility of hazardous reactions, including a statement whether the chemical will react of polymerize, which could release excess pressure of heat, or create other hazardous conditions.
Also, a description of the conditions under which a hazardous reaction may occur. The first step in preparing an MSDS is to collect information about the material and its components including physical, chemical and environmental characteristics, and toxicity information. The collected information is then evaluated and assessed to determine the potential physical fire and reactivity , health and environmental hazards associated with the material.
Then, using professional judgement, the product is classified according to the hazard criteria specified in legislation of the country where the product will be used. This legislation defines the criteria for categorizing controlled products into various classes. Several classes have subclasses to provide more specific information about particular kinds of hazards. The CPR should be consulted to find out what the criteria are that are used to classify chemical products as flammable versus combustible or toxic versus very toxic, and so on.
The supplier must use professional, scientific judgement when evaluating the test results of the product or, where appropriate, a product with similar properties. The supplier also has the duty to report any hazard information of which he or she is "aware or ought reasonably to be aware" [see subsections 12 11 and 33 2 of the CPR]. The toxicology information must be presented in such a way "so as not to mislead a person as to the nature or extent of the hazard posed by the controlled product" [subsection Those who prepare MSDSs for chemical products used in workplaces in other countries should consult the legislation in those jurisdictions to find out their requirements for product classification, labelling and information to be disclosed in MSDSs.
Since then several guidelines and standards have been prepared. This standard specifies:. The objective of this standard is to "create consistency in providing information on safety, health and environmental matters for chemical products". The GHS addresses the classification of chemicals by types of hazard health, fire, reactivity, environmental and proposes harmonized hazard communication elements labels and safety data sheets.
It is intended that the GHS will be adopted worldwide. Canadian regulatory authorities have said that they will accept the heading format if all the information required by the CPR is included.
It was prepared by a committee with user input from numerous labour representatives, government officials, professional associations, industry associations and academic groups. The standard has information about the appearance and readability of MSDSs. It explains where technical and non-technical language should be used to optimize MSDS usefulness to different groups of readers.
For example, medical information can be provided under the subheading "Notes to the Physician" in the section "First Aid Measures". Non-technical language should be used in sections intended for use by the employee e.
It also provides advice about font types and sizes, page layouts and so on that make MSDSs easier to read. The standard also provides a list of commonly used phrases and the extensive glossary to help suppliers write MSDSs clearly without an extensive use of technical terms or jargon. For example, the phrase ". To prevent skin contact, "wear chemical resistant clothing such as gloves, apron, boots or whole body suits made from Neoprene, as appropriate" is more precise and helpful than "wear chemical resistant clothing".
