I don't think you could ever pickle your curtains enough to make them fire proof. It surely would leave nasty stains! Impregnation sprays are quite cheap, some are suitable for washing, even.

We are opening a bargain shop in a Bradford shopping area. One large room upstairs and a cellar with little customer and staff toilet. Top room about 30ft by 25ft. Bottom 23ftx20ft. Cubicle 4x5ft. There is some emergency lighting already. No smoke alarms or panel. The backdoor in the top room is locked all the time to prevent theft. Following some scary prosecutions (Poundstretcher etc) we want to carry out a fire risk assessment and get up to speed. Can anybody help with recommendations?
