I don't wan't a substance in my house either that could go BANG!! at any given moment in time. Some people say however that it is a stable as pyrodex, just easier to ignite.

Opinions?
I think it can act as an explosive, rather than a propellant like Pyrodex or nitro. So accidental ignition can result in an explosion rather than a fire. It was used as a blasting material for hundreds of years and I believe the 'power-monkey' had a relatively short lifespan. Monkey make mistake tamping it down, Monkey go 'BOOM'.

Here is some info on differences
