They dont know what they are talking about. I asked about the threat posed by Cyanogen chloride, they hadnt even heard of it. (incidentally no mask will protect you from this blood thickening agent) they also seem to pick prices from thin air and are clearly profiteering.
In the end I had two superb masks sent from the uk by gasmasks-direct.co.uk. There people gave me good advice and also supplied a reasonably priced chemical suit. The stuff arrived within 4 days of ordering and the amount has not yet been deducted from my credit card.
