Grade compares Spectrum 183's OSHA Total Case Rate to the BLS industry benchmark across 4 years of Form 300A filings (2016–2024). This reflects reported recordable injuries, not an independent safety inspection -- underreporting is a known limitation of employer self-recordkeeping.

Trend analysis for Spectrum 183
Between 2021 and 2024, Spectrum 183's Total Case Rate worsened from 2.4 to 4.8 recordable injuries per 100 full-time workers, a 103% increase across 3 years of OSHA reporting.
The safest year on record was 2022, at a TCR of 0.0, while 2024 saw the highest rate, at 4.8, a spread of 4.8 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 4 reporting years, Spectrum 183 recorded 4 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 4-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)
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.
0 DART incidents × 200,000 ÷ 82,647 hours worked = 0.00 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Spectrum 183's reported OSHA injury record, strong versus its Aircraft assemblies, subassemblies, and parts (except engines) manufacturing peers, but not a guarantee about any single site today.
- At 71% of the Aircraft assemblies, subassemblies, and parts (except engines) manufacturing benchmark, Spectrum 183 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 Aircraft assemblies, subassemblies, and parts (except engines) 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.
