Trend analysis for Jefferson North Assembly Plant
Between 2016 and 2019, Jefferson North Assembly Plant's Total Case Rate held roughly steady from 3.1 to 3.0 recordable injuries per 100 full-time workers, a 4% decrease across 3 years of OSHA reporting.
The safest year on record was 2017, at a TCR of 2.6, while 2016 saw the highest rate, at 3.1, a spread of 0.5 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 4 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 4 reporting years, Jefferson North Assembly Plant recorded 474 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 4-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 (2019)
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.
99 DART incidents × 200,000 ÷ 9,687,367 hours worked = 2.04 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
