The verdict

STL runs at 834% of its industry's injury rate - far more dangerous than the typical Industrial testing laboratories or services workplace, earning a grade F.

STL: 4.2 TCR = 834% of Industrial testing laboratories or services BLS 0.5 · 2y Form 300A (see methodology below)

STL safety composite

STL scores strongest on dart rate (safer than 71% of same-industry peers) and weakest on total case rate (tcr) (safer than 12%), 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).

STL has fewer employees than the Industrial testing laboratories or servi median and a higher injury rate than the industry's median TCR of 1.0. 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.
