2,119 Caisson (i.e., drilled buildin establishmentsSafer than 36% of graded establishments in this industry, whose median TCR is 2.0.

Trend analysis for McKinney Drilling Company
Between 2016 and 2019, McKinney Drilling Company's Total Case Rate worsened from 2.4 to 3.4 recordable injuries per 100 full-time workers, a 41% increase across 3 years of OSHA reporting.
The safest year on record was 2016, at a TCR of 2.4, while 2019 saw the highest rate, at 3.4, a spread of 1.0 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, McKinney Drilling Company recorded 47 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)
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.
7 DART incidents × 200,000 ÷ 824,044 hours worked = 1.70 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
