Trend analysis for Clean Harbors Environmental Services, Inc.
Between 2018 and 2019, Clean Harbors Environmental Services, Inc.'s Total Case Rate held roughly steady from 1.2 to 1.2 recordable injuries per 100 full-time workers, a 5% decrease across 1 year of OSHA reporting.
The safest year on record was 2019, at a TCR of 1.2, while 2018 saw the highest rate, at 1.2, a spread of 0.1 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, Clean Harbors Environmental Services, Inc. recorded 188 total injuries and illnesses and 1 fatality. 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 (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.
47 DART incidents × 200,000 ÷ 17,023,642 hours worked = 0.55 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
