The verdict

Luminalt runs at 333% of its industry's injury rate - far more dangerous than the typical Low voltage electrical work workplace, earning a grade F.

Luminalt: 9.3 TCR = 333% of Low voltage electrical work BLS 2.8 · 2y Form 300A (see methodology below)

Luminalt safety composite

Luminalt scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 2%), 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).

Luminalt has fewer employees than the Low voltage electrical work median and a higher injury rate than the industry's median TCR of 2.5. 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.
