THE FALTALY INJURED PERSON WAS USING THE BUCKET OF THE SCOOP TO HOLD DOWN A HEAD DRIVE THAT WAS BALANCED IN THE CENTER ON CRIB BLOCKS. THE LEFT SIDE OF THE SCOOP BUCKET SLIPPED OFF THE HEAD DR IVE. WHEN THAT HAPPENED THE OPERATOR'S SIDE WAS THROWN INTO THE MINE ROOF CATCHING HIS HEAD AND NECK BETWEEN SCOOP AND ROOF.

ⓘ
This rate is recorded citations divided by MSHA inspection hours, per 100 hours. It reflects inspection effort, not mine size or production.ⓘ
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.ⓘ
Shares are computed over citations that carry the MSHA gravity and negligence coding; a small share of records are uncoded.ⓘ
A sample is a point in time compliance measurement, not an individual exposure history. These figures describe MSHA sampling records and do not establish causation or personal dose.Respirable coal dust
ⓘ
Respirable coal dust and silica figures cover coal facilities. Dust compliance is measured against the current 1.5 mg/m3 standard; samples predating the 2014 standard are included, so compliance rates are a coarse historical signal.

1 recordedWhere Ralph Napier 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.
