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.

PORTABLE CRUSHER sits in Lac qui Parle County, Minnesota, where the Census mining category is 0.2% 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.

October 25, 2023MN · Metal/Non-Metalcrusher attendant/operator, pan feeder operator/workerMACHINERY
The operator tried to dislodge clay buildup from a return roller on the top return belt on the crusher. The crusher was running at this time. The operator tried to lay a 12" pry bar against the roller to knock the clay off. The operator inserted the pry bar too far which caused the belt to grab the bar and pull the operator's left hand and wrist in between the belt and roller.
