That chemical fire was an education to watch. It confused even the trained firefighters.
I work in a facility with all of the above mentioned chemicals (and a whole lot worse). We have an excellent relationship with the local FD but I think they would tell you that they will rely on us to tell them what X and Y is if there was a response.
Hazmat crews will be more comfortable with these calls but their response time is measured in hours, not minutes (4hrs I think for an initial response for my area).
