The verdict

Quartz runs at 13% of its industry's injury rate - far safer than the typical Substation and switching station, power transmission line, construction workplace, earning a grade A.

Quartz: 0.3 TCR = 13% of Substation and switching station, power transmission line, construction BLS 2.8 · 2y Form 300A (see methodology below)

Quartz safety composite

Quartz scores strongest on total case rate (tcr) (safer than 93% of same-industry peers) and weakest on dart rate (safer than 45%), 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).
