ⓘ
Esta tasa son las citaciones registradas divididas entre las horas de inspección de la MSHA, por cada 100 horas. Refleja el esfuerzo de inspección, no el tamaño de la mina ni la producción.ⓘ
Las diferencias entre las multas propuestas y las pagadas reflejan tanto acuerdos y reducciones en conferencia como montos aun adeudados. Pendiente es el saldo que se debe actualmente.ⓘ
Las proporciones se calculan sobre las citaciones que llevan la codificación de gravedad y negligencia de la MSHA; una pequeña parte de los registros no está codificada.ⓘ
Esta tasa son los casos de lesión reportables por cada 100 trabajadores a tiempo completo por año, calculada como 200,000 por los casos dividido entre las horas-empleado reportadas por el operador a la MSHA. Los casos son lesiones que la MSHA clasificó en grado 01 a 07; se excluyen los eventos de solo accidente que no lesionaron a nadie, y también las lesiones de contratistas, cuyas horas no corresponden a una sola mina. Las tasas comienzan en el año 2000, cuando inicia el reporte trimestral de empleo, y se omiten por debajo de 20,000 horas en un año.| Año | tasa de casos totales | días perdidos | mortales |

Where Martin Marietta Materials Inc 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.
