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: 906 inspection hours is too few for a stable rate. A minimum of 1,000 inspection hours is required.

MSHA sampling at Marett Mine shows 100% of 88 respirable coal dust samples met the 1.5 mg/m3 standard.
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.
Respirable coal dust
ⓘRespirable coal dust and silica figures cover coal facilities. Dust compliance is measured against the current 1.5 mg/m3 standard; samples predating the 2014 standard are included, so compliance rates are a coarse historical signal.

It describes the sampled workplace, not what reached the miner's ear: hearing conservation programs and the hearing protection worn during the shift are recorded separately and are not reflected here.

Marett Mine recorded 3.83 reportable injury cases per 100 full-time workers in 2011.
Injury rate, 2011
ⓘ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
About average. The US coal mining average was 3.83 and the all-US-mining average was 3.08 cases per 100 workers.
In Pennsylvania, coal mining averaged 4.31 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.

Marett Mine sits in Butler County, Pennsylvania, where the Census mining category is 0.5% 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.

March 31, 2011PA · Coalbulldozer operator, universal operator, heavy equipment operator, operating engineerSLIP OR FALL OF PERSON
The employee was exiting an excavator, climbing down the tracks to the step. He slipped from the step and fell to the ground landing on his lunch box. There was, according to other employees, some mud on the step. The employee was angry in leaving his equipment, due to the fact that he was to quit operating one piece and start operating another.
The employee was working on the outside of a hopper that became jammed with material. He was using a pry bar to clear material from the hopper (were it discharges onto a belt). The employee had the bar resting on his shoulder using his legs for power. Later in the day a pain developed and continued to get worse. He went to the local E.R. & was diagnosed with tendonitis/strain.
