Bob, I did find I could easilly move the burning box, and have some worries that a strong stream might spread the fire. Another reason to do the oval movement idea so as maybe to get below and above the heart of the fire.
Yeah, worrying about when things have gone too far for an extinguisher is a real consideration. Hope I'll never have to do it for real, but some fake experience is a heck of a lot better than none. Tom
