The springloaded punch is the way to go, but I have heard that a "Broken piece of ceramic", as in a peice of Spark Plug will uncork a piece of Safety Glass when struck. Something about the irregular/crystalline nature of the ceramic disrupting the molecular integrity of the safety glass.
Lexan /Polycarbonate "Plexiglas" is totally different from automotive safety glass.
EMTs, what can you folks expand on this. Bill is looking for ideas here to make a life saving tool for you and the rest of us.
Thanks, and take care.
