Where Ralph Johnson et al stands on silica, penalties, and injury rate

MSHA's standard limits respirable silica to 50 micrograms per cubic metre, but MSHA publishes dust and quartz as separate files and never the silica figure itself. We derive it per sample, score it against the limit, and set the operator's injury rate against a benchmark built from the full MSHA operator record. With the 26-year penalty trail, contest posture, and fatality history. Delivered as a PDF with the underlying data as CSV.

The federal record itself stays free on this site. What costs money, and why.
