i wondered the same thing, why wait over a week with symptoms before getting medcal assistance?

fireranger, couldn't the flame be sucked into the can causing it to explode?

 

Nope. It is pressurized forcing the product out and keeping the fire from going in. And, there is no oxygen inside the can or tube leading into the can. It only becomes a flammable mixture once it is outside the can.

 

i did some thing like that i was cleaning a dish washer at a resteruant and i mixed discaler and bleach by mistake and it mad mustard gas i for got to hit the swich that turns the bleach pump from pumping in to the diswasher the hole resterand had to get cleared out
