Horizon LLC: 0.8 TCR = 27% of Plumbing contractors BLS 2.8 · 4y Form 300A (see methodology below)

Horizon LLC safety composite

Horizon LLC scores strongest on total case rate (tcr) (safer than 92% of same-industry peers) and weakest on dart rate (safer than 29%), 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).
