Trend analysis for General Dynamics Electric Boat
Between 2016 and 2021, General Dynamics Electric Boat's Total Case Rate worsened from 3.1 to 4.6 recordable injuries per 100 full-time workers, a 48% increase across 5 years of OSHA reporting.
The safest year on record was 2016, at a TCR of 3.1, while 2021 saw the highest rate, at 4.6, a spread of 1.5 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 6 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 6 reporting years, General Dynamics Electric Boat recorded 1,990 total injuries and illnesses and 1 fatality. Readers comparing establishments should weigh the 6-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 (2021)
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.
453 DART incidents × 200,000 ÷ 24,632,583 hours worked = 3.68 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
