citations per 100 inspection hours
ⓘThis rate is recorded citations divided by MSHA inspection hours, per 100 hours. It reflects inspection effort, not mine size or production.
Rate withheld: 340 inspection hours is too few for a stable rate. A minimum of 1,000 inspection hours is required.

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.

PLANT #102 sits in Kalamazoo County, Michigan, where the Census mining category is 0.1% 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.

Quarterly safety rates
ⓘCitations per million reported employee-hours. Rates begin in 2000, when MSHA's quarterly employment data starts; earlier incidents are counted but cannot be rate-adjusted. Quarters under 100,000 reported hours are greyed: too few hours for a stable rate.

September 13, 2024MI · Metal/Non-Metallaborer, blacksmith, bull gang, parts runner, roustabout, pick-up man, pitmanSLIP OR FALL OF PERSON
Employee was working on some gravel equipment. he finished and was climbing down the ladder. He said he missed the bottom step of the ladder, and he rolled his left ankle over when he stepped on the ground. He thought he sprained it, but he broke the left fibula bone.
EE was doing maintenance on jaw crusher. He was standing on step ladder, with his feet about 2' off the ground, when the wrench slipped, causing him to lose his balance. An angle iron bracket that holds the control box (box was removed for access) went into his armpit, causing a cut. He never fell, but was able to remain standing until help arrived, about 30 seconds later.
