Trend analysis for Tul-Tulsa-Maintenance Base
Between 2017 and 2019, Tul-Tulsa-Maintenance Base's Total Case Rate improved from 7.5 to 5.2 recordable injuries per 100 full-time workers, a 31% decrease across 2 years of OSHA reporting.
The safest year on record was 2019, at a TCR of 5.2, while 2017 saw the highest rate, at 7.5, a spread of 2.3 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, Tul-Tulsa-Maintenance Base recorded 662 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 (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.
155 DART incidents × 200,000 ÷ 9,925,451 hours worked = 3.12 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
