Trend analysis for DW Zinser Company, Inc.
Between 2016 and 2020, DW Zinser Company, Inc.'s Total Case Rate held roughly steady from 6.7 to 6.8 recordable injuries per 100 full-time workers, a 1% increase across 4 years of OSHA reporting.
The safest year on record was 2018, at a TCR of 5.1, while 2020 saw the highest rate, at 6.8, a spread of 1.7 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, DW Zinser Company, Inc. recorded 6 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 (2020)
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.
0 DART incidents × 200,000 ÷ 29,619 hours worked = 0.00 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
