The verdict

STS runs at 168% of its industry's injury rate - more dangerous than the typical Assembly machines manufacturing workplace, earning a grade D.

STS: 5.5 TCR = 168% of Assembly machines manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

STS safety composite

STS scores strongest on dart rate (safer than 78% 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).

STS has more employees than the Assembly machines manufacturing median and a higher injury rate than the industry's median TCR of 2.7. 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.
