ⓘ
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 |

Lawrenceburg Quarry & Mill se ubica en Lawrence County, Tennessee, donde la categoría minera del Censo representa el 0.1% del empleo del condado.
ⓘ
Las cifras del condado provienen de la Encuesta sobre la Comunidad Estadounidense de la Oficina del Censo de EE. UU., estimaciones quinquenales agrupadas, por lo que la edición de 2023 abarca de 2019 a 2023. La categoría del Censo es 'minería, explotación de canteras y extracción de petróleo y gas', que es más amplia que la jurisdicción de la MSHA e incluye a trabajadores de petróleo y gas que ninguna mina emplea. Estas cifras describen el condado circundante, no esta mina, y no son un factor en ningún incidente específico.ⓘ
Citaciones por millón de horas-empleado reportadas.
