Where Subzero Engineering falls in its industry
542 Screen doors, metal frame, man establishmentsSafer than 64% of graded establishments in this industry, whose median TCR is 3.9.

Trend analysis for Subzero Engineering
Between 2020 and 2024, Subzero Engineering's Total Case Rate held roughly steady from 2.3 to 2.3 recordable injuries per 100 full-time workers, a 0% change across 4 years of OSHA reporting.
The safest year on record was 2023, at a TCR of 2.0, while 2021 saw the highest rate, at 4.6, a spread of 2.6 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 5 reporting years, Subzero Engineering recorded 16 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 5-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.
2 DART incidents × 200,000 ÷ 343,081 hours worked = 1.17 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
