HMIRS is the central repository for Material Safety Data Sheets (MSDS) for the United States Government military services, civil agencies and their contractors. HMIRS access is restricted to U.S. government employees and government-sponsored contractors. It is not open to the general public, however a civilian version is commercially available (see below). This system was previously called HMIS through May 2002, but the name was changed, in part, to avoid conflict with other similarly-named systems: HMISÂ® which is most commonly known for its familiar colored bar labeling scheme.
