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.

Arizona #1 recorded 3.96 reportable injury cases per 100 full-time workers in 2013.
Injury rate, 2013
ⓘ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
Above average. The US metal and nonmetal mining average was 2.46 and the all-US-mining average was 2.99 cases per 100 workers.
In Arizona, metal and nonmetal mining averaged 2.37 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.

Arizona #1 sits in Coconino County, Arizona, 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.

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.

While riding the conveyance down the shaft at a slow pace, employee tried knocking off a piece of timber from the shaft steel set getting his right index finger caught between conveyance and guide resulting in a laceration requiring 8 sutures.
Crew was using a cutting torch to remove inaccessable guide bolts; a piece of molten metal inadvertantly fell down the shaft. It is unknown what was smoldering as the shaft is under rehabilitation at this time and it is unsafe to travel down the shaft to extinguish the fire.
