FDC's for sprinkler systems
Recently at my firehouse, we have been talking about and doing a simulated fire at a building with an FDC for the sprinkler systems. When my shift was doing our simulation, the building we were dealing with was a grocery store with a fire in the loading dock area. On arrival, the "conditions" were smoke and fire showing from this loading dock, and the sprinkler system was active. My chief decided that instead of our 4 man engine company hitting the FDC, we would let the sprinkler system work w/out our assistance, and we simulated an aggressive offensive attack on the loading dock. the evaluators of the scenario acted as if my chief committed a crime by not hooking into the FDC. In a post scenario critque, our shift discussed the tatics used and supported them by stating: that if the sprinkler is keeping the fire at bay, an aggressive fire attack with the sprinkler system operating is sometimes an acceptable strategy. My questions are: Why is it preached as it is ALWAYS a MUST to hook to the FDC? If you hook into the FDC for the sprinkler system and use a hydrant that is on the same feed as the sprinkler system, are you really able toboost the pressure and get more water flowing into the system? If any one can answer these questions I would appreciate it. My chief has looked in all the books around the station and can not find an explanation on the absolute reason why it is imperative to hook the FDC vs. using it in conjunction with an aggressive attack.
