Trend analysis for North America : Grinnell Doors
Between 2021 and 2023, North America : Grinnell Doors's Total Case Rate held roughly steady from 8.2 to 7.8 recordable injuries per 100 full-time workers, a 4% decrease across 2 years of OSHA reporting.
The safest year on record was 2022, at a TCR of 6.7, while 2021 saw the highest rate, at 8.2, a spread of 1.4 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 3 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 3 reporting years, North America : Grinnell Doors recorded 63 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 3-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 (2023)
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.
19 DART incidents × 200,000 ÷ 613,583 hours worked = 6.19 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
