Email me when a new MSHA incident is filed at any mine Al Meyers controls.
THE VICTIM HAD BEEN HAND-MUCKING AT THE BOTTOM OF THE SHAFT PRIOR TO SIGNALING THE SURFACE TO BE HOISTED OUT. THE SURFACE ATTENDANT DESCENDED THE SHAFT AFTER THE HOIST RIGGING ARRIVED AT THE S URFACE WITHOUT THE VICTIM ON IT. HE FOUND THE VICTIM UNCONSCIOUS, WITH NO VITAL SIGNS, NEAR THE BOTTOM OF THE SHAFT. THE AUTOPSY REPORT INDICATED IT WAS CARBON MONOXIDE POISONING.
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.
