Muestreo de salud
Una muestra es una medicion de cumplimiento en un momento dado, no un historial de exposicion individual. Estas cifras describen registros de muestreo de MSHA y no establecen causalidad ni dosis personal.
Polvo respirable de carbon
Las cifras de polvo respirable de carbon y silice corresponden a instalaciones de carbon. El cumplimiento del polvo se mide frente a la norma actual de 1.5 mg/m3; se incluyen muestras anteriores a la norma de 2014, por lo que las tasas de cumplimiento son una senal historica aproximada.
