This afternoon at 14:03 hours our engine was requested into Piscataway to standby at River Road’s firehouse while they operated on a structure fire. Engine 562 responded with a 3 man crew and stood by for approximately 2 1/2 hours. During the cover assignment the crew responded with Ladder 27 to a mulch fire. On arrival the crew stretched the 1 3/4 inch bumper line to extinguish the fire. Units were clear of the fire in approximately 10 minutes. Engine 562 was clear of Piscataway at approximately 16:30.
