Brad Clayton Posted January 4, 2011 Share Posted January 4, 2011 There is a very real danger of evap smoke testing machines becoming bombs. Recently, a tech hooked up the Rotunda smoke machine to a vehicles evap line and for whatever reason was called away. It was sometime before he returned to the vehicle and the whole time the tester line was hooked to the vehicles evap line. The tech continued the test and as soon as the button was pressed the machine blew up. The tech wasn't hurt but the rear of the machine and internals were damaged beyond repair. This is along the same lines as why lift motors are mounted chest high or on new Rotary lifts all the way at the top of the lift. Electric motors producing sparks and flamable vapors are a bad combination. I really can't remember what my policy was in the past, but now the tester hose is never conected to the vehicle other than if a test is actually being run.
