The safest year on record was 2024, at a TCR of 9.8, while 2023 saw the highest rate, at 10.3, a spread of 0.4 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 2 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 2 reporting years, Marble's Gun Sights, Inc. recorded 6 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 (2024)
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.
0 DART incidents × 200,000 ÷ 60,919 hours worked = 0.00 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
