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.

St. Marys Sand recorded 0.00 reportable injury cases per 100 full-time workers in 2023.
Injury rate, 2023
ⓘ
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.0.00

fatality rate
Below average. The US metal and nonmetal mining average was 1.78 and the all-US-mining average was 2.10 cases per 100 workers.
In Georgia, metal and nonmetal mining averaged 1.26 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.

St. Marys Sand sits in Charlton County, Georgia, 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.Charlton County, Georgia · Population 12,711

Employee was washing out around the scale when EE felt discomfort on right leg above the ankle near the top of where EE's pull on boots came too. The area looked red and a little festered so EE was sent to the doctor. The doctor diagnosed it as an abscess and prescribed an antibiotic. the employee returned to work at full duty.

HANDLING OF MATERIALS
Winona Sand & Gravel · Struck by... (Not Elsewhere Classified)
EE's were replacing the head pulley on a conveyor belt. The roller and shaft are conn. to a housing with an electric motor. When the last bolt was removed the housing rotated down, it impacted the EE on the upper thigh and calf on his right leg. The weight of the housing impacting his leg caused a puncture to his calf and the bolt hit his femur.
