The safest year on record was 2020, at a TCR of 1.6, while 2021 saw the highest rate, at 15.4, a spread of 13.9 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 8 reporting years, Dee Zee Main recorded 76 total injuries and illnesses, with no fatalities reported in any of those years.

DART Rate, Transparent Calculation (2023)
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.
4 DART incidents × 200,000 ÷ 640,570 hours worked = 1.25 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
