Trend analysis for Mapei West Chicago
Between 2016 and 2024, Mapei West Chicago's Total Case Rate improved from 3.0 to 2.1 recordable injuries per 100 full-time workers, a 27% decrease across 8 years of OSHA reporting.
The safest year on record was 2024, at a TCR of 2.1, while 2016 saw the highest rate, at 3.0, a spread of 0.8 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, Mapei West Chicago recorded 21 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 (2024)
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.
6 DART incidents × 200,000 ÷ 561,066 hours worked = 2.14 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
