Don't know how you're going to make that easier for Squeaky - but I'm sure nana can explain (good luck!).

I always question pyrotechnics used inside ever since the Great White Tragedy:

It happened so quickly! The cameraman was fortunate in the extreme that he was able to get out.

Couldn't get any video footage of that, but part of the trouble must lie with the soundproofing materials used in walls and ceilings.

Acoustic foams, tiles, mats and so on aren't always fire-proof, or give off toxic fumes at melting point. I've heard that fibreglass membranes used in soundproofing are much better, but probably more expensive, and the venue where Great White played, probably had none of that.

Accidents like that are terrible.

well, that was unpleasant.... one never really thinks of how fast the smoke can incapacitate you...

we used to live in the s. c. "chicken coops", cheap housing for the masses, with nothing but narrow slits for basement windows. how that is legal is beyond my comprehension for nobody over the age of 1 could have squeezed out of their gaps. would it really have been too expensive to have real windows instead? especially with their aluminum wiring...

Smoke inhalation's one of the biggest killers in fire situations.

This is a vid made by the Derby Fire Services. Although it's shown under controlled conditions, it's an example of what can happen if you try to put out a chip pan or barbecue fire using water. If polystyrene kitchen tiles'd been in place, they would've melted very quickly, resulting in black toxic smoke - as well as the inferno.

It's not just the fire itself that causes a problem, but in how you put one out.
