I found fire retardant stuff on the internet and mail ordered. I
don't remember where, though I remember there were lots of places.
But here's what I want to tell you, though. I think that, if at all
possible, you are better off buying flame retardant fabric. The
liquid I bought either didn't actually work, if I merely sprayed it
on, then tested as the fire marshals do, or if I dipped and dried
the fabric, left it coated with salt or equivalent-- very ugly, even
after shaking and brushing. If others have had better luck, I look
forward to hearing about it, as I'll probably have to deal with this
again this year.
By the way, just as a point of interest, this was for ACC Chicago,
and, after all my work to meet all the stringent rules, no one
checked anything. Extension cords, total wattage, fire
susceptibility, nothing. My neighbor had twice the allowed wattage.
I'd be interested in other people's experience at big show halls
like Navy Pier or the Merchandise Mart in Chicago, or other ACC
shows and the like elsewhere. Are these things enforced mostly? Are
they enforced strictly some places? Has anybody been given a really
hard time? Where? Thanks!
