Trend analysis for Hingham Manufacturing
Between 2021 and 2023, Hingham Manufacturing's Total Case Rate improved from 2.9 to 1.4 recordable injuries per 100 full-time workers, a 51% decrease across 2 years of OSHA reporting.
The safest year on record was 2023, at a TCR of 1.4, while 2021 saw the highest rate, at 2.9, 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 3 reporting years, Hingham Manufacturing recorded 13 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 (2023)
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.
4 DART incidents × 200,000 ÷ 571,541 hours worked = 1.40 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
