Between 2017 and 2018, Design Space Modular Buildings's Total Case Rate held roughly steady from 0.0 to 5.2 recordable injuries per 100 full-time workers, a 0% change across 1 year of OSHA reporting.
The safest year on record was 2017, at a TCR of 0.0, while 2018 saw the highest rate, at 5.2, a spread of 5.2 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 2 reporting years, Design Space Modular Buildings recorded 6 total injuries and illnesses, with no fatalities reported in any of those years.

DART Rate, Transparent Calculation (2018)
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.
3 DART incidents × 200,000 ÷ 230,880 hours worked = 2.60 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
