The verdict

Materials Test Lab runs at 331% of its industry's injury rate - far more dangerous than the typical Electrip Power Distribution workplace, earning a grade F.

Materials Test Lab: 4.0 TCR = 331% of Electrip Power Distribution BLS 1.2 · 3y Form 300A (see methodology below)

Materials Test Lab safety composite

Materials Test Lab scores strongest on dart rate (safer than 79% of same-industry peers) and weakest on total case rate (tcr) (safer than 30%), 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 #122 safest of 260 Electrip Power Distribution employers in California.

Materials Test Lab (35 employees, TCR 4.0) among 29 same-industry peers, split at the industry median of 56 employees and a TCR of 2.5

Materials Test Lab has fewer employees than the Electrip Power Distribution median and a higher injury rate than the industry's median TCR of 2.5.
