What makes you think that barium chlorate mixtures will spontaneously ignite ?
I'll test how sensitive they are after I synthesize some Ba(ClO3)2 and I'll report the results here.
Finally I considered to not trust some warnings from Bill Ofca's, especially on the calcium sulfate, carbonate and copper oxide side. If he likes to warn us, why didn't he tell that dextrin sensitizes chlorates so much ?

I was talking about a dedicated pyro building. You can't really control the humidity outside.
By the way, do you know if this static protection spray can be home made ? I heard it was water + something sticky.

Also, while working with static sensitive compositions like flash, you must make sure that the local humidity is +50%. High levels of it lower drastically the chance of a big static charge accumulation. As the others above me said, you shouldn't use plastics. Use a cardboard or wooden case to put your flash powder in. Also wearing synthetic clothes can be very hazardous, wear cotton.
Static poses the most big dangers to volatile fuel/air mixtures. As you can see from the video that chris m posted, gasoline fumes mixed with air ignite with ease. There was similair accident reported in APC. A guy was using acetone for binding stars if I remember correctly, when spontaneously the fumes self ignited, firing all his compositions and chemicals.

I can't see why you shouldn't spray it with normal water ?

You will see my work, don't worry about it.
It's just a matter of time for my to resume my pyro activity, resume filming and posting to this forum.
However I must admit that I know almost nothing about rocketry, which seems to be your preferred section in pyro.
I'm more a shell guy, but maybe the rocketry will get interesting for me in future.
