Email me when a new MSHA incident is filed at any California Portland Cement Company mine.
UVICTIM WAS WORKING IN CLINKER BUILDING ON A PLATFORM ON A TRAVELING CRANE DECK. THE CRANE DECK WAS IN A STATIONARY POSITION AND THE VICTIM WAS USING A 6\ LONG STEEL BAR PRYING ON A RAIL. THE BAR SLIPPED AND THE VICTIM FELL BACKWARDS OFF THE DECK ONTO THE GROUND BELOW. THE GROUND WAS LOCATED APPROX. 70\ BELOW THE PLATFORM AND THE BIC VICTIM WAS KILLED INSTANTLY.
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.
