Tuolumne Division: 3.2 TCR = 85% of Ambulance services, air or ground BLS 3.8 · 4y Form 300A (see methodology below)

Tuolumne Division safety composite

Tuolumne Division scores strongest on total case rate (tcr) (safer than 84% of same-industry peers) and weakest on fatalities (safer than 51%), 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).

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #11 safest of 87 Ambulance services, air or gro employers in California.

Tuolumne Division (45 employees, TCR 3.2) among 29 same-industry peers, split at the industry median of 72 employees and a TCR of 8.3

Tuolumne Division has fewer employees than the Ambulance services, air or ground median and a lower injury rate than the industry's median TCR of 8.3. 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.
