		<description>Air has an average MW = 29, chlorine MW = 70.91.  2.4X as heavy as air is not &quot;slightly&quot;.  Burning pool chlorinator is silly as such and certainly as a source of free chlorine.  PCP - a tertiary amine - in PVC would decompose the polymer during extrusion, typically 175 C.  PCP itself boils around 310 C.  As the hydrochloride one might expect less drama.  Alas,

http://en.wikipedia.org/wiki/Phencyclidine#History_and_medicinal_use

thermal scission of the hydrochloride to a tertiary benzil carbocation is facile.  About 5 mg up the nose will get you trippy.  Let&#039;s try 5 mg in 5 ml water ingested (conservatively large volume).  If 10,000 gallons went through the piping (conservatively small volume),  that requires 84 lbs PCP release.  Seems unlikely.</description>
