Trend analysis for NSK Corporation
Between 2018 and 2024, NSK Corporation's Total Case Rate worsened from 1.1 to 1.7 recordable injuries per 100 full-time workers, a 53% increase across 6 years of OSHA reporting.
The safest year on record was 2018, at a TCR of 1.1, while 2019 saw the highest rate, at 2.6, a spread of 1.5 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 7 reporting years, NSK Corporation recorded 27 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 7-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.
3 DART incidents × 200,000 ÷ 480,350 hours worked = 1.25 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
