Iron Mountain Hydro: 3.0 TCR = 247% of Electric power generation, hydroelectric BLS 1.2 · 2y Form 300A (see methodology below)

Iron Mountain Hydro safety composite

Iron Mountain Hydro scores strongest on total case rate (tcr) (safer than 54% of same-industry peers) and weakest on dart rate (safer than 21%), 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).
