The verdict

Lumentum Bloomfield runs at 46% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Lumentum Bloomfield: 1.5 TCR = 46% of Semiconductor devices manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Lumentum Bloomfield safety composite

Lumentum Bloomfield scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 28%), 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).

Where Lumentum Bloomfield falls in its industry

437 Semiconductor devices manufact establishments

Safer than 30% of graded establishments in this industry, whose median TCR is 0.9.

Grade A

More dangerous than peersSafer than peers

Narrower to Connecticut alone (the establishments it most directly competes with for workers and contracts): ranked #3 safest of 4 Semiconductor devices manufact employers in Connecticut.

Lumentum Bloomfield (146 employees, TCR 1.5) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Lumentum Bloomfield has fewer employees than the Semiconductor devices manufacturing median and a higher injury rate than the industry's median TCR of 0.9. 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.
