Trend analysis for Michigan Department of Corrections
Between 2018 and 2020, Michigan Department of Corrections's Total Case Rate worsened from 2.0 to 30.5 recordable injuries per 100 full-time workers, a 1396% increase across 2 years of OSHA reporting.
The safest year on record was 2018, at a TCR of 2.0, while 2020 saw the highest rate, at 30.5, a spread of 28.5 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.
Summed across those 3 reporting years, Michigan Department of Corrections recorded 13 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 3-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2020)
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
60 DART incidents × 200,000 ÷ 393,245 hours worked = 30.52 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
