The verdict

Gow Mac Instrument Co runs at 65% of its industry's injury rate - safer than the typical Laboratory analytical optical instruments (e.g., microscopes) manufacturing workplace, earning a grade B.

Gow Mac Instrument Co: 2.1 TCR = 65% of Laboratory analytical optical instruments (e.g., microscopes) manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Gow Mac Instrument Co safety composite

Gow Mac Instrument Co scores strongest on dart rate (safer than 77% of same-industry peers) and weakest on total case rate (tcr) (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).

Gow Mac Instrument Co (30 employees, TCR 2.1) among 29 same-industry peers, split at the industry median of 80 employees and a TCR of 1.8

Gow Mac Instrument Co has fewer employees than the Laboratory analytical optical instrument median and a higher 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.
