The verdict

Sigray, Inc. runs at 31% of its industry's injury rate - far safer than the typical Laboratory analytical optical instruments (e.g., microscopes) manufacturing workplace, earning a grade A.

Sigray, Inc.: 1.0 TCR = 31% of Laboratory analytical optical instruments (e.g., microscopes) manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

Sigray, Inc. safety composite

Sigray, Inc. scores strongest on dart rate (safer than 77% of same-industry peers) and weakest on fatalities (safer than 50%), 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).

Sigray, Inc. (62 employees, TCR 1.0) among 29 same-industry peers, split at the industry median of 80 employees and a TCR of 1.8

Sigray, Inc. has fewer employees than the Laboratory analytical optical instrument median and a lower injury rate than the industry's median TCR of 1.8. 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.
