Trend analysis for WD-40 Company

Between 2018 and 2024, WD-40 Company's Total Case Rate improved from 1.1 to 0.0 recordable injuries per 100 full-time workers, a 100% decrease across 6 years of OSHA reporting.

The safest year on record was 2020, at a TCR of 0.0, while 2018 saw the highest rate, at 1.1, a spread of 1.1 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, WD-40 Company recorded 6 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 ÷ 502,329 hours worked = 0.00 DART

Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

  • At 15% of the Rust preventive preparations manufacturing benchmark, WD-40 Company reports fewer injuries than typical peers, still worth asking how safety is managed day to day. Know your rights
  • Judge this record against the wider Rust preventive preparations manufacturing sector, where injury rates vary widely, before comparing it in isolation. See the industry
  • Grades reflect 2016–2024 filings; check the latest establishment record straight from OSHA, or look up a different employer. Look up another

Safety grades reflect employers' self-reported OSHA Form 300A filings from 2016 to 2024 and can lag current conditions. A grade is not a guarantee that any specific workplace is safe or unsafe today. See our methodology and disclaimer.
