I'd like to mirror what was said earlier as it's a very important thing to remember. Most facilities require you to be certified in their facility. Here, in Portland, the Union requires you to be "certified" in every venue. This goes for the operation of any type of machinery, forklift, manlift, scissor ect.
I do find it weird that the "Union" said you should be certified. Usually the local will have training classes a few times a year to get a bunch of folks certified, they then work with the local venues to get all their members qualified at the individual venues.
After all that, any local rentor, or leasor of Lifts should offer a certification class for a nominal fee.
