Sig73 when will this new practice stop? Are they looking at this? Just assigning the relocator because they are in the response area? The relocator is providing coverage. The Dispatcher should wait and assign those companies normally due. Am I wrong?
Assigning companies pre-determined by distance to respond on multiple alarms and having relocators assigned separately from beyond the 5th alarm was a clever solution to a simple problem. Prior to radio communications, once a company was assigned to respond or relocate via telegraph, they could not be contacted until they arrived at their destination. If next alarm companies were being relocated, they could not be contacted and redirected to respond to the next alarm until they arrived at their destination firehouses. The problem would have been worse when multiple alarms were struck in rapid succession.
This approach was unique to FDNY primarily because it was one of the very few cities that had resources available beyond the 5th alarm. Even in New York, the concept was modified. Staten Island only had 3 alarms worth of companies so the 4th and 5th alarms were relocators.
Radio made it possible to redirect companies even if they were on the road.
In the late 1970’s, coverage was determined by Response Neighborhoods (RNs). With the heavy activity of the time and multiple simultaneous fires, dynamic (not pre-determined) relocations were made to minimize uncovered RNs. Uncovering an RN to cover a different RN was not the best solution, so distant RNs had to be considered. The computer also calculated the relative value of potential relocations as a function of time. Since relocators frequently went to work also, staging companies in strategic firehouses was another solution.
Where responses are determined dynamically from actual company locations (by radio or AVL), companies ‘on the air’ have no turnout time while companies in quarters are assessed a turnout time. A company on the street in front of the firehouse will have a shorter potential response time than a company dispatched from within that firehouse.
