The verdict

Pioneer Circuits Inc. runs at 72% of its industry's injury rate - safer than the typical Printed circuit assemblies manufacturing workplace, earning a grade B.

Pioneer Circuits Inc.: 2.4 TCR = 72% of Printed circuit assemblies manufacturing BLS 3.3 · 6y Form 300A (see methodology below)

Pioneer Circuits Inc. safety composite

Pioneer Circuits Inc. scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 20%), 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).
