The verdict

Jefferson runs at 172% of its industry's injury rate - more dangerous than the typical Machine shops workplace, earning a grade D.

Jefferson: 5.7 TCR = 172% of Machine shops BLS 3.3 · 2y Form 300A (see methodology below)

Jefferson safety composite

Jefferson scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 7%), 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).
