PORTABLE CRUSHER #25 recorded 0.00 reportable injury cases per 100 full-time workers in 2005.
Injury rate, 2005
ⓘ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
No reportable injury cases in any year shown. Employee-hours were reported in each of those years, so these are true zeros rather than missing data. Citations, listed in the compliance record above, are inspector-found violations and are counted separately from worker injuries.
Below average. The US metal and nonmetal mining average was 3.76 and the all-US-mining average was 4.21 cases per 100 workers.
In Arizona, metal and nonmetal mining averaged 3.92 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.

PORTABLE CRUSHER #25 sits in Maricopa 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 working on the cone crusher top assembly, employee A was holding bolt with wrench. Employee B was loosening nut with an impact wrench; when torque was applied to the nut employee A lost grip on wrench causing wrench to make contact with employee B's face resulting in damage to mouth requiring five external stitches and 2 internal stitches.

While working near the jaw crusher a rock fell and hit the miner a glancing blow to the left shoulder. The primary contributing factor was the miners location - too close to the jaw. After a trip to the clinic on his way home, it was determined that the only damage was bruising. The miner returned to work the next day to regular duty. There was no time loss, but he saw a doctor.
