Trend analysis for Coherent Monrovia

Between 2021 and 2024, Coherent Monrovia's Total Case Rate held roughly steady from 0.0 to 0.0 recordable injuries per 100 full-time workers, a 0% change across 3 years of OSHA reporting.

The safest year on record was 2021, at a TCR of 0.0, while 2021 saw the highest rate, at 0.0, a spread of 0.0 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 4 years with a usable rate on file, rather than one outlier year skewing the multi-year average.

Summed across those 4 reporting years, Coherent Monrovia recorded 0 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)

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.

0 DART incidents × 200,000 ÷ 32,565 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 Coherent Monrovia's reported OSHA injury record, strong versus its Laboratory analytical optical instruments (e.g., microscopes) manufacturing peers, but not a guarantee about any single site today.

  • At 0% of the Laboratory analytical optical instruments (e.g., microscopes) manufacturing benchmark, Coherent Monrovia 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 Laboratory analytical optical instruments (e.g., microscopes) 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.
