Trend analysis for Thousand Oaks Manufacturing
Between 2018 and 2023, Thousand Oaks Manufacturing's Total Case Rate worsened from 1.0 to 1.4 recordable injuries per 100 full-time workers, a 41% increase across 5 years of OSHA reporting.
The safest year on record was 2018, at a TCR of 1.0, while 2023 saw the highest rate, at 1.4, a spread of 0.4 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, Thousand Oaks Manufacturing recorded 27 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 (2023)
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.
8 DART incidents × 200,000 ÷ 1,131,165 hours worked = 1.41 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
