One of the other quips I've heard about CFl3 is that the best piece of safety equipment for dealing with a large spill of it is "a good pair of running shoes".
On a fun note, at the jobsite of my 1st job, Aldrich Chemical, they had a little incident in the packaging warehouse involving a large cylinder of sulphur trioxide, which is basically gaseous, anhydroys sulphuric acid. The fuse plug melted on the cylinder, releasingthe entire cylinder, which combined with moisture in the air to form HOT concentrated sulphuric, which rained down and destriyed everything made of paper and metal in the warehouse.
Then there was the time when the metals storage room and the pyrophorics storage room went up in the Boranes lab building where I worked. It was probably started by something less than stabile- likea flask of methyl aluminum distillates ir pot residues, or a derelict flask of triethyl arsenate- I heard it was a pretty fire (happened on 3rd shift) with cylinders of of various organo-lithium cylinders rocketing out of the building streaming red flames. The heat generated in that room set off the sprinklers in the metals storage room, with fantastic results- a couple hundred kilos if sodium, potassium, lithium, and hydrides of each were stored there.
