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

WECO has $5K in proposed MSHA penalties and $470 outstanding across 0 contested dockets.
Penalty disposition

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.

WECO recorded 2.90 reportable injury cases per 100 full-time workers in 2025.
Injury rate, 2025
ⓘ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 and are withheld below 20,000 hours in a year. Employment reports reach back to 1983, but those earlier years come from MSHA's archived file format and are not used in rates.

fatality rate
Above average. The US metal and nonmetal mining average was 1.65 and the all-US-mining average was 1.98 cases per 100 workers.
In Puerto Rico, metal and nonmetal mining averaged 2.64 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.

WECO sits in Vega Alta Municipio, Puerto Rico, where the Census mining category is 0.0% 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; earlier incidents are counted but not rate-adjusted, though reported hours reach back to 1983. Quarters under 100,000 reported hours are greyed: too few hours for a stable rate.
