From the press release:
The U.S. Department of Labor today announced enhancements to its online enforcement database designed to improve public access to and understanding of the department’s enforcement actions. The updated website includes a number of new features, including map displays of inspection and violation data from the department’s Occupational Safety and Health Administration and its Mine Safety and Health Administration, as well as the ability to view individual inspection records and the enforcement history of a particular company or mine….
…In addition to mapping capabilities, the updated site allows users to easily view important agency metrics; perform keyword searches; filter data by year, violations or penalties; and export search results or an entire data set into downloadable formats. A new “labs” feature allows users to create data visualizations and animations using several decades of MSHA data.
