Like others say, hands-on is crucial. Probably more so, and not said outright, is that hands-on training is practically useless unless you continue to practice. Maybe not every day for the rest of your life, but at least until you've got it down cold. Think of riding a bike; it may be years, but you can do it again. Why? Cuz most kids ride for daily for several years.

ScouterMan mentions his need to practice, and I concur. I've had some Hazmat training, with the Class A suit, but only twice. I'd never try to do it in real life, simply becuase I never got it down well the first time.

I'd try looking for something better, maybe via FDNY (despite the probably long commute for you), or in NJ.
