Health sampling
ⓘ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.
Metal and nonmetal contaminants (personal samples)
ⓘMany samples are screening measurements of substances with no applicable exposure limit; they are counted as samples but excluded from every over-limit figure. Over-limit shares use only limit-tested samples.

Cedarapids 3042 Jaw Crusher S/N 289-05-2 sits in Humboldt County, Nevada, where the Census mining category is 20.1% 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.

Employee was working off of an 8'step ladder tightening bolts. While over reaching the wrench slipped and employee fell about 5' to the ground. Employee was not tied off and over reaching, and did not maintain 3 points of contact. Ladders are not work platforms. These contributing factors are what caused his injuries, laceration to his head and one broken rib.
