Trend analysis for Cork Supply USA, Inc.

Between 2017 and 2024, Cork Supply USA, Inc.'s Total Case Rate worsened from 2.5 to 3.1 recordable injuries per 100 full-time workers, a 24% increase across 7 years of OSHA reporting.

The safest year on record was 2017, at a TCR of 2.5, while 2020 saw the highest rate, at 11.1, a spread of 8.6 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, Cork Supply USA, Inc. recorded 25 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)

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.

2 DART incidents × 200,000 ÷ 196,080 hours worked = 2.04 DART

Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
