Trend analysis for Chesapeake Optical Lab
Between 2022 and 2023, Chesapeake Optical Lab's Total Case Rate improved from 4.7 to 2.5 recordable injuries per 100 full-time workers, a 47% decrease across 1 year of OSHA reporting.
The safest year on record was 2023, at a TCR of 2.5, while 2022 saw the highest rate, at 4.7, a spread of 2.2 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, Chesapeake Optical Lab recorded 12 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 (2023)
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 ÷ 320,781 hours worked = 1.25 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
