Links to free material safety data sheets are available on the Occupational Safety & Health Administration (OSHA) and Mine Safety and Health Administration (MSHA) websites, reports the U.S. Department of Labor. An information services company called 3E hosts a database of millions of links to free material safety data sheets at MSDS.com.
According to the Hazard Communications Standard, revised in 2012, manufacturers, distributors and importers of hazardous chemicals must provide safety data sheets, formerly known as material safety data sheets, for each product, states OSHA. As of 2015, the safety data sheet must be in a 16-section format. Sections one through eight contain general identification and handling procedures, sections nine through 11 and 16 have scientific and technical information, and sections 12 through 15 deal with classification and labeling. If those dealing with hazardous chemicals do not have safety data sheets, OSHA recommends contacting the manufacturer.
