The verdict

Kaiser Optical Systems, Inc. runs at 35% of its industry's injury rate - far safer than the typical Laboratory analytical optical instruments (e.g., microscopes) manufacturing workplace, earning a grade A.

Kaiser Optical Systems, Inc.: 1.1 TCR = 35% of Laboratory analytical optical instruments (e.g., microscopes) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Kaiser Optical Systems, Inc. safety composite

Kaiser Optical Systems, Inc. scores strongest on total case rate (tcr) (safer than 66% of same-industry peers) and weakest on dart rate (safer than 18%), 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).

Where Kaiser Optical Systems, Inc. falls in its industry

145 Laboratory analytical optical establishments

Safer than 66% of graded establishments in this industry, whose median TCR is 1.8.

Grade A

More dangerous than peersSafer than peers

Narrower to Michigan alone (the establishments it most directly competes with for workers and contracts): ranked #3 safest of 7 Laboratory analytical optical employers in Michigan.

Kaiser Optical Systems, Inc. (93 employees, TCR 1.1) among 29 same-industry peers, split at the industry median of 80 employees and a TCR of 1.8

Kaiser Optical Systems, Inc. has more 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.
