A fter some discussion it appeared that hydrochloric arid fames could be given off when P -Y .C . is exposed to etevaced temperatures.

At whai point con fianve arrestors be' discon tinued, and is there any size tank vthhh would not require flame arrestors? It tras pointed out that various fire in surance ijispection bureaus have varied stand ards. Th e Factory Insurance Association or Radon,- Mutual Company could be cansulled lai some specific problem. The ccmsoisus appeared to be that flame arresters would not be required when the flash point was in excess fOCh F. There way no definite con clusion regarding size of storage vessels; a1- - though it appeared that any lank or fcetllc inside % building should la v e its vent pro tected with some flame arrestor when in flammable liquid service.
