The verdict

Head Quarters runs at 16% of its industry's injury rate - far safer than the typical Low voltage electrical work workplace, earning a grade A.

Head Quarters: 0.5 TCR = 16% of Low voltage electrical work BLS 2.8 · 5y Form 300A (see methodology below)

Head Quarters safety composite

Head Quarters scores strongest on total case rate (tcr) (safer than 94% of same-industry peers) and weakest on dart rate (safer than 30%), 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).
