Yeah, they do make a mess. At a previous job, a certain co-worker had the habit of sticking a C02 fire extinguiser under the restroom stall door when I was in there and freezing my rear end off. He just thought it was funnier than heck. Did it to everybody. I thought I'd fix him and took a fire extinguisher in there with me for several days. Sooo, the day he tries it again, I blast back at him. Well, being a kid, I did not know the difference between a dry powder extinguisher and C02.
Needless to say, he was quite upset... /forums/images/graemlins/tongue.gif
