The verdict

Shop runs at 128% of its industry's injury rate - more dangerous than the typical Duct work (e.g., cooling, dust collection, exhaust, heating, ventilation) installation workplace, earning a grade D.

Shop safety composite

Shop scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 47%), 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).
