Where Sila Nanotechnology falls in its industry
103 Fibers, carbon and graphite, m establishmentsSafer than 76% of graded establishments in this industry, whose median TCR is 3.0.
Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #2 safest of 10 Fibers, carbon and graphite, m employers in California.
Trend analysis for Sila Nanotechnology
Between 2021 and 2022, Sila Nanotechnology's Total Case Rate improved from 1.2 to 0.9 recordable injuries per 100 full-time workers, a 29% decrease across 1 year of OSHA reporting.
The safest year on record was 2022, at a TCR of 0.9, while 2021 saw the highest rate, at 1.2, a spread of 0.4 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 2 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 2 reporting years, Sila Nanotechnology recorded 6 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 (2022)
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 ÷ 683,640 hours worked = 0.59 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping

What this grade means for you
Use this grade as a relative read on Sila Nanotechnology's reported OSHA injury record, strong versus its Fibers, carbon and graphite, manufacturing peers, but not a guarantee about any single site today.
- At 32% of the Fibers, carbon and graphite, manufacturing benchmark, Sila Nanotechnology 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 Fibers, carbon and graphite, 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.
