The verdict

Cornerstone Dairy runs at 120% of its industry's injury rate - more dangerous than the typical Dairy Farm workplace, earning a grade D.

Cornerstone Dairy: 5.4 TCR = 120% of Dairy Farm BLS 4.5 · 2y Form 300A (see methodology below)

Cornerstone Dairy safety composite

Cornerstone Dairy scores strongest on total case rate (tcr) (safer than 55% of same-industry peers) and weakest on dart rate (safer than 34%), 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).

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #55 safest of 205 Dairy Farm employers in California.

Cornerstone Dairy (29 employees, TCR 5.4) among 29 same-industry peers, split at the industry median of 37 employees and a TCR of 6.0

Cornerstone Dairy has fewer employees than the Dairy Farm median and a lower injury rate than the industry's median TCR of 6.0. 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.
