A really useful article. For those not aware, Phosgene gas is the stuff the Nazis used in their extermination camps!
In a past employment I used to show visitors around our oil seal manufacturing plant, the metal pressings were all phosphate coated and that part of the plant had 'Positively No Smoking' notices everywhere. Visitors were always astounded to learn that the minute quantities of chemical which escaped into the atmosphere could be conveted into Phosgene gas when superheated by the burning end of a cigarette, and guess where that ends up?
So, a very pertinent question is - how many people use brake or other solvent cleaners in their workshops, and also smoke in there? And how long is the atmosphere still dangerous after using the stuff?
Still smoking? Enjoy it - it may be your last! :cry:
