ProTech Thermal Services: 7.5 TCR = 227% of Heat treating ovens, industrial process-type, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

ProTech Thermal Services safety composite

ProTech Thermal Services scores strongest on dart rate (safer than 79% 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).
