Chronos Imaging safety composite

Chronos Imaging scores strongest on fatalities (safer than 52% of same-industry peers) and weakest on dart rate (safer than 13%), 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).

Safer than 42% of graded establishments in this industry, whose median TCR is 1.2.

Grade A

More dangerous than peersSafer than peers

Narrower to Illinois alone (the establishments it most directly competes with for workers and contracts): ranked #2 safest of 4 Irradiation apparatus and tube employers in Illinois.

Chronos Imaging (82 employees, TCR 1.3) among 29 same-industry peers, split at the industry median of 130 employees and a TCR of 1.2

Chronos Imaging has fewer employees than the Irradiation apparatus and tubes (e.g., i median and a higher injury rate than the industry's median TCR of 1.2. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
