Trend analysis for Plumbing Masters
Between 2016 and 2017, Plumbing Masters's Total Case Rate worsened from 13.9 to 18.7 recordable injuries per 100 full-time workers, a 34% increase across 1 year of OSHA reporting.
The safest year on record was 2016, at a TCR of 13.9, while 2017 saw the highest rate, at 18.7, a spread of 4.8 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, Plumbing Masters recorded 7 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 (2017)
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.
5 DART incidents × 200,000 ÷ 64,207 hours worked = 15.57 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
