The verdict

CA-21 runs at 45% of its industry's injury rate - far safer than the typical Electric power generation, solar workplace, earning a grade A.

CA-21: 0.5 TCR = 45% of Electric power generation, solar BLS 1.2 · 4y Form 300A (see methodology below)

CA-21 safety composite

CA-21 scores strongest on total case rate (tcr) (safer than 61% of same-industry peers) and weakest on dart rate (safer than 32%), 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).

Benchmarked live against every credibly-rated employer in the same NAICS industry code in the current OSHA extract (a segment must have at least 8 rated peers to benchmark). Not a legal or compliance determination; PlainSafetyScore's own weighting (TCR 40%, DART 35%, fatalities 25%).

Rising injury rate

CA-21: 0.3 → 0.7 TCR

Peak year 2019 @ 0.8 TCR · DART/TCR 1.15× in 2020

CA-21's TCR rose 0.5 from 0.3 in 2017 to 0.7 in 2020. Peak filing year was 2019 at 0.8 TCR. In 2020, DART was 1.15× this establishment's average TCR (severity share of cases).

Where CA-21 falls in its industry

157 Electric power generation, sol establishments

Safer than 61% of graded establishments in this industry, whose median TCR is 1.2.

Grade A

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #16 safest of 32 Electric power generation, sol employers in California.

CA-21 (4,525 employees, TCR 0.5) among 29 same-industry peers, split at the industry median of 208 employees and a TCR of 1.2

CA-21 has more employees than the Electric power generation, solar median and a lower 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.
