I did some work with a major US chemical company once in their development labs and they used quite a bit of Hydrofluoric Acid. They had to brief me on all of the possible dangers in the lab building (which were many) as that was their policy for contractors. The entire complex was designed for testing and had blow out walls, containment rooms, special air handling systems, etc. They said they once had an accidental release of the gas and the cloud floated across the parking lot and etched the car glass as it floated by. They had sealed containment rooms for running tests with that stuff. They used the acid as a feed chemical to produce teflon based products. The guys I was working with advised me to avoid walking in that area of the building since any exposure to the chemical would likely mean death. It is a really nasty chemical. http://en.wikipedia.org/wiki/Hydrofluoric_acid Dave --- This email is free from viruses and malware because avast!
