Avísenme cuando se presente un nuevo incidente de la MSHA en cualquier mina que controle Rigsby & Barnard Quarry Inc et al.
THE MILL WAS SHUT DOWN FOR THE LUNCH PERIOD. THE CRUSHER OPERATOR ASKED THE SUPERINTENDER TO LOOK AT THE BELT FROM THE PRIMARY CRUSHER SCREENS TO THE SECONDARY CRUSHER TO DETERMINE THE CAUSE O F SPILLAGE FROM THE BELT. THE SUPERINTENDENT GOT UP ON THE CONVEYOR AND FELL OFF, 14 FEET TO THE GROUND.
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.
