Hey, something I can help with.  Yes phosgene and mustard gas are the same, 
both blistering agents formed when a reactive halide (like Iodine, 
clorine or flourine gas) comes into close proximity of a good catalyst 
like copper or brass.  The old halide fire extinguishers would form 
phosgene if they came into contact with something brass, like say a door 
knob or fauset.  Nice thing to worry about when you're running out of a 
burning building. Funny how the only inorganic chemistry lectures I 
remember are the ones that taught me how to make weapons or octane boosters.
