Trend analysis for Mitsubishi Chemical Carbon Fiber & Composites
Between 2017 and 2020, Mitsubishi Chemical Carbon Fiber & Composites's Total Case Rate improved from 4.1 to 1.2 recordable injuries per 100 full-time workers, a 71% decrease across 3 years of OSHA reporting.
The safest year on record was 2020, at a TCR of 1.2, while 2017 saw the highest rate, at 4.1, a spread of 2.9 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 2 reporting years, Mitsubishi Chemical Carbon Fiber & Composites recorded 9 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 2-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)
What is the DART rate formula?
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.
2 DART incidents × 200,000 ÷ 336,208 hours worked = 1.19 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
