The verdict

Store 1 runs at 170% of its industry's injury rate - more dangerous than the typical Manufacturing workplace, earning a grade D.

Store 1: 5.6 TCR = 170% of Manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Store 1 safety composite

Store 1 scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 23%), 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).
