Trend analysis for Primus Aerospace-MD
Between 2023 and 2024, Primus Aerospace-MD's Total Case Rate improved from 4.7 to 1.7 recordable injuries per 100 full-time workers, a 64% decrease across 1 year of OSHA reporting.
The safest year on record was 2024, at a TCR of 1.7, while 2023 saw the highest rate, at 4.7, a spread of 3.0 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, Primus Aerospace-MD recorded 4 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 2-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.
1 DART incidents × 200,000 ÷ 117,205 hours worked = 1.71 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Primus Aerospace-MD's reported OSHA injury record, strong versus its Aeronautical systems and instruments manufacturing peers, but not a guarantee about any single site today.
- At 97% of the Aeronautical systems and instruments manufacturing benchmark, Primus Aerospace-MD 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 Aeronautical systems and instruments 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.
