The verdict

JMT Services runs at 94% of its industry's injury rate - about level with the typical Air vent installation workplace, earning a grade C.

JMT Services: 2.6 TCR = 94% of Air vent installation BLS 2.8 · 4y Form 300A (see methodology below)

JMT Services safety composite

JMT Services scores strongest on total case rate (tcr) (safer than 59% of same-industry peers) and weakest on dart rate (safer than 29%), 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).

Grade C

More dangerous than peersSafer than peers

Narrower to Delaware alone (the establishments it most directly competes with for workers and contracts): ranked #15 safest of 32 Air vent installation employers in Delaware.

JMT Services (37 employees, TCR 2.6) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

JMT Services has fewer employees than the Air vent installation median and a lower injury rate than the industry's median TCR of 3.3. 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.
