How Do I Read MSDS?

A material safety data sheet (MSDS) is created to provide specific information about chemicals designated hazardous by the Occupational Safety and Health Administration. While the government does require a MSDS to contain certain information about the chemical, the format differs from company to company. Here is what you need to know about reading the MSDS.

  1. Manufacturer and Basic Product Information

    • Most MSDSs contain information about the manufacturer, including full company name, physical address and phone numbers. Also listed at or near the top of the page, you will find the product name and federal classification numbers, including the Federal Supply Class (FSC) and National Item Identification Number (NIIN), which do not always appear on a MSDS.

    Product Composition and Physical Data

    • MSDSs contain listings of the hazardous contents, formulas and characteristics of all chemicals, including color, odor and appearance, contained within the product. This information will help in identification of a product in the event of spills or leakage.

    Safety and Hazard Information

    • Each MSDS contains information on what to do in case of contamination, fire, spills or contact with the human body. It will list specific health hazards and procedures for reducing or eliminating danger after exposure to the hazardous chemicals contained within the product. The MSDS also provides direction on cleanup and disposal of the product.

    Storage and Handling Information

    • Directions for proper storage, including light levels, temperature and requirements for separation from other chemicals are included on the MSDS. Proper handling techniques are also indicated, including what safeguards, such as goggles, gloves and other protective wear, are needed.

    Where to Find the MSDS

    • While specific procedures may vary, any company that uses or manufactures hazardous chemical products must provide labeling and MSDSs to any workers that will be exposed and provide proper training in usage and handling of these substances. If you are unsure of where to find MSDS information, ask your supervisor or human resources administrator for more information.
