Ahhh yes, it's FOON BALL time of year...I miss seeing those mishap reports...
and i was the safety officer in my last command. had the most entertaining lectures, too - most of the hazards and incidents i was talkin about actually happened to me.
i often commented that my current body is primarily composed of scar tissue.
One of the best 'balls of flame' I've seen comes from water sprayed on a grease fire. Some years ago I used to work in a restaurant which, upon request, would cook steaks in what we called 'Pittsburgh style' - steak cooked in a stainless steel pan on a gas burner, pour in melted butter and let it catch fire - the steak comes out medium-well to well-done on the outside but rare on the inside. After the steak is done, squirting the dishwasher spray hose at the burning pan results in a ball of flame rising up to greet the ceiling tiles.
