MSDS forms are required for a wide range of products, chiefly chemicals, under laws of the U.S., Canada, and many other nations. They’re intended to protect occupational health and safety. Material Safety Data Sheets are specific to each chemical agent. They contain manufacturer contact information, hazardous ingredients, fire safety, explosion and reactivity data, health hazards, precautions for safe handling, and use and control measures, such as protection for skin, eyes or lungs. They are the sophisticated cousins of the cautions-and-warnings labeling on consumer products.

The U.S. government offers an online database that includes abbreviated information from the Material Safety Data Sheets of hundreds of products by brand name. This service is available at the Household Products Database, which is sponsored by the National Institutes of Health.
