When our Genie lift was taken away from us by the insurance company (it was an older model that did not require the outriggers to be in before lifting the bucket, and the outriggers were long gone anyway), they gave us a 2-high section of rolling scaffold. Not quite high enough to get to things 40' in the air, so we would put an 8' ladder on top of two plywood boxes (approx 2-3'), on top of the scaffold deck.
Although it wasn't related, we also used to climb up the back of the telescoping sections of the genie lift, and walk around on the pipe grids in our black box theatre. OSHA? Who's that?
