Trend analysis for Warren Systems Inc

Between 2019 and 2024, Warren Systems Inc's Total Case Rate held roughly steady from 0.0 to 0.0 recordable injuries per 100 full-time workers, a 0% change across 5 years of OSHA reporting.

The safest year on record was 2019, at a TCR of 0.0, while 2022 saw the highest rate, at 5.6, a spread of 5.6 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.

Summed across those 6 reporting years, Warren Systems Inc recorded 2 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 6-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.

0 DART incidents × 200,000 ÷ 56,704 hours worked = 0.00 DART

Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
