The verdict

NTI National Technologies runs at 63% of its industry's injury rate - safer than the typical Low voltage electrical work workplace, earning a grade B.

NTI National Technologies: 1.8 TCR = 63% of Low voltage electrical work BLS 2.8 · 3y Form 300A (see methodology below)

NTI National Technologies safety composite

NTI National Technologies scores strongest on total case rate (tcr) (safer than 63% of same-industry peers) and weakest on dart rate (safer than 25%), 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).
