Trend analysis for King Electrical Mfg Co.
Between 2019 and 2022, King Electrical Mfg Co.'s Total Case Rate improved from 11.3 to 9.7 recordable injuries per 100 full-time workers, a 15% decrease across 3 years of OSHA reporting.
The safest year on record was 2021, at a TCR of 6.3, while 2019 saw the highest rate, at 11.3, a spread of 5.1 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 3 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 3 reporting years, King Electrical Mfg Co. recorded 30 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 3-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 (2022)
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.
10 DART incidents × 200,000 ÷ 248,481 hours worked = 8.05 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
