The verdict

Main Office and all other sites: 0.6 TCR = 23% of Sewage treatment plant construction BLS 2.8 · 3y Form 300A (see methodology below)

Main Office and all other sites safety composite

Main Office and all other sites scores strongest on total case rate (tcr) (safer than 94% of same-industry peers) and weakest on dart rate (safer than 52%), 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).
