This section tells you who wrote the MSDS, their address and telephone number, and the date when it was written or last revised. An MSDS is valid for three years after it is produced or last revised. There may be additional sections in an MSDS with more information on environmental effects. There are many sources of additional information, including The Canadian Chemical Producers Association,The Canadian Centre For Occupational Health and Safety, industry associations, universities, environmental organizations, federal and provincial ministries, the library and the Internet. As well, there are chemical, health and environmental indexes in the library, on disc or on the Internet.
Many databases are now on the Internet.
If you do not have home or office access, your local library or educational institution can probably provide access to the Internet for you, even if you do not know how to operate a computer. Some Internet sites may charge a fee for services provided. These searches will provide a list of appropriate information sources. Both libraries and the Internet have chemical and environmental abstracts that list most of the available information sources under appropriate categories. If you cannot get information on regulated or unregulated ingredients in a product, you can look in a chemical formula text book that lists typical formulas for many products.
