Time Mark Corporation: 0.7 TCR = 22% of Timing devices, mechanical and solid-state (except clockwork), manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Time Mark Corporation safety composite

Time Mark Corporation scores strongest on total case rate (tcr) (safer than 78% of same-industry peers) and weakest on fatalities (safer than 51%), 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 Time Mark Corporation falls in its industry

156 Timing devices, mechanical and establishments

Safer than 78% of graded establishments in this industry, whose median TCR is 1.3.

Grade A

More dangerous than peersSafer than peers

Narrower to Oklahoma alone (the establishments it most directly competes with for workers and contracts): ranked #1 safest of 4 Timing devices, mechanical and employers in Oklahoma.

Time Mark Corporation (38 employees, TCR 0.7) among 29 same-industry peers, split at the industry median of 99 employees and a TCR of 1.3

Time Mark Corporation has fewer employees than the Timing devices, mechanical and solid-sta median and a lower injury rate than the industry's median TCR of 1.3. 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.
