The verdict

North Office runs at 72% of its industry's injury rate - safer than the typical Electrical contractors workplace, earning a grade B.

North Office: 2.0 TCR = 72% of Electrical contractors BLS 2.8 · 3y Form 300A (see methodology below)

North Office safety composite

North Office scores strongest on total case rate (tcr) (safer than 58% of same-industry peers) and weakest on dart rate (safer than 47%), 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).
