The verdict

Solid Energy Systems LLC runs at 50% of its industry's injury rate - far safer than the typical Storage batteries manufacturing workplace, earning a grade A.

Solid Energy Systems LLC: 1.6 TCR = 50% of Storage batteries manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Solid Energy Systems LLC safety composite

Solid Energy Systems LLC scores strongest on dart rate (safer than 84% of same-industry peers) and weakest on fatalities (safer than 51%), 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).

Narrower to Massachusetts alone (the establishments it most directly competes with for workers and contracts): ranked #4 safest of 7 Storage batteries manufacturin employers in Massachusetts.

Solid Energy Systems LLC (57 employees, TCR 1.6) among 29 same-industry peers, split at the industry median of 107 employees and a TCR of 2.1

Solid Energy Systems LLC has fewer employees than the Storage batteries manufacturing median and a lower injury rate than the industry's median TCR of 2.1.
