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.

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.

Hyd. hoses on conv were too short; came off. Safety valve was activated, stopping conv from moving. Cat skid steer was used to hold conv to reconnect hoses. An oil leak caused conv to start settling. EE's arm was positioned in conv in order to reconnect the hoses; not realizing conv was slowly settling. The conv was on his arm when he realized what was happening, pinning it.
