The verdict

Sierra Instruments, Inc. runs at 18% of its industry's injury rate - far safer than the typical Gas flow instrumentation, industrial process-type, manufacturing workplace, earning a grade A.

Sierra Instruments, Inc.: 0.6 TCR = 18% of Gas flow instrumentation, industrial process-type, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Sierra Instruments, Inc. safety composite

Sierra Instruments, Inc. scores strongest on total case rate (tcr) (safer than 82% of same-industry peers) and weakest on dart rate (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).
