The verdict

Porter Corp runs at 68% of its industry's injury rate - safer than the typical Buildings, prefabricated metal, manufacturing workplace, earning a grade B.

Porter Corp: 2.3 TCR = 68% of Buildings, prefabricated metal, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Porter Corp safety composite

Porter Corp scores strongest on total case rate (tcr) (safer than 75% 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).
