Hi,
I'm still new to practical coiling but I have a 1KVA system and I go 
by the assumptions "Treat it with the same respect as TNT" and "All 
sparks are lethal".  Fooling around with HV AC streamers is one step 
closer to the end and I'm sure the more experienced coilers will say 
the same thing.  As a physical precaution I always have at hand a 
C02 extinguisher and a nylon tube about 1.5M long.  As an electrical 
precaution I have RCD, MOV and filters.  I do however operate 
indoors, which some would say is a bad idea.
Thanks
Chris
