The verdict

Groton CT runs at 436% of its industry's injury rate - far more dangerous than the typical Engineering research and development laboratories or services workplace, earning a grade F.

Groton CT: 2.2 TCR = 436% of Engineering research and development laboratories or services BLS 0.5 · 6y Form 300A (see methodology below)

Groton CT safety composite

Groton CT scores strongest on dart rate (safer than 70% of same-industry peers) and weakest on total case rate (tcr) (safer than 16%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

Groton CT has fewer employees than the Engineering research and development lab median and a higher injury rate than the industry's median TCR of 0.8. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
