Trend analysis for ABC Supply 051
Between 2023 and 2024, ABC Supply 051's Total Case Rate improved from 19.6 to 8.1 recordable injuries per 100 full-time workers, a 59% decrease across 1 year of OSHA reporting.
The safest year on record was 2024, at a TCR of 8.1, while 2023 saw the highest rate, at 19.6, a spread of 11.5 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 2 reporting years, ABC Supply 051 recorded 12 total injuries and illnesses, with no fatalities reported in any of those years. 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 (2024)
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.
4 DART incidents × 200,000 ÷ 98,517 hours worked = 8.12 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
