Reckon it will not catch fire spontaneously but will help things alon quite well if a fire breaks out from other sources. Only my opinion bu why not throw it away? If it is in the loft it means you do not need t look at it. If you do not look at it, you do not need it - go on, b brave, throw away the crap. This of course is unless they are girli mags, in which case construct a small cupboard next to the toilet there are many people on the site who will be happy to advise about th best method of construction
