The verdict

1800 runs at 106% of its industry's injury rate - about level with the typical Roofing contractors workplace, earning a grade C.

1800: 3.0 TCR = 106% of Roofing contractors BLS 2.8 · 9y Form 300A (see methodology below)

1800 safety composite

1800 scores strongest on dart rate (safer than 79% 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).
