The verdict

Johnson Thermal Systems runs at 282% of its industry's injury rate - far more dangerous than the typical Buildings, prefabricated metal, manufacturing workplace, earning a grade F.

Johnson Thermal Systems: 9.3 TCR = 282% of Buildings, prefabricated metal, manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Johnson Thermal Systems safety composite

Johnson Thermal Systems scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 11%), 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).
