Trend analysis for Knoxville Lab
Between 2016 and 2024, Knoxville Lab's Total Case Rate held roughly steady from 0.0 to 0.5 recordable injuries per 100 full-time workers, a 0% change across 8 years of OSHA reporting.
The safest year on record was 2016, at a TCR of 0.0, while 2017 saw the highest rate, at 1.3, a spread of 1.3 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, Knoxville Lab recorded 7 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.
1 DART incidents × 200,000 ÷ 408,817 hours worked = 0.49 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
