Select General Order 050 Sup 39 2008 to see the new (2008) FDNY guidance on HandiTalkies and HandiTalkie IDs Their portable radio IDs are very simple - Engine 1 - Engine 1 Chauffeur - Engine 1 Can - Engine 1 Control - Engine 1 Hydrant - something like that Ladder 1 - Ladder 1 Chauffeur - Ladder 1 Roof - Ladder 1 OV (Outside Vent) There is also info here admonishing pump operators to always get a positive supply of water, and not to overextend themselves when delivering big water. (PS - centrifigal pump produce lower pressures at higher GPM - strange but true) (PPS - water mains and hoselines produce greater friction losses at higher flows - this is another way to run out of water at the big one) (PPPS - IIRC, the optimum flow rate for water is 10 feet per second - no matter the size of the main or hose) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "massfire" group.
