Johnson Technology, Inc.: 0.6 TCR = 19% of Aircraft engine and engine parts (except carburetors, pistons, piston rings, valves) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Johnson Technology, Inc. safety composite

Johnson Technology, Inc. scores strongest on total case rate (tcr) (safer than 83% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers.
