SIERRA BLANCA recorded 3.89 reportable injury cases per 100 full-time workers in 2002.

Injury rate, 2002
This rate is reportable injury cases per 100 full-time-equivalent workers per year, computed as 200,000 times cases divided by MSHA operator-reported employee-hours. Cases are injuries MSHA graded degree 01 through 07; accident-only events that hurt no one are excluded, and so are contractor injuries, whose hours do not attach to a single mine. Rates begin in 2000, when quarterly employment reporting starts, and are withheld below 20,000 hours in a year.

fatality rate
Below average. The US metal and nonmetal mining average was 4.17 and the all-US-mining average was 5.05 cases per 100 workers.
In Texas, metal and nonmetal mining averaged 3.17 cases per 100 workers that year.
Under 100,000 employee-hours were reported that year, so a single case moves the rate by two or more. Read the figure as approximate.

2001 * 15.87 15.87 0.000
2000 * 3.84 3.84 0.000
* Fewer than 100,000 employee-hours that year; the rate is less stable.

SIERRA BLANCA sits in Hudspeth County, Texas, where the Census mining category is 0.0% of county employment.

Local economic context
County figures come from the US Census Bureau's American Community Survey, 5-year pooled estimates, so the 2023 vintage covers 2019 through 2023. The Census category is 'mining, quarrying, and oil and gas extraction', which is broader than MSHA jurisdiction and includes oil and gas workers no mine employs. These figures describe the surrounding county, not this mine, and are not a factor in any specific incident.
