At 21:41 Station 3 was alerted for its second first due house fire in 24 hours in the 12800 Block of Frederick Road in the 3-1 box. Callers passing by advised Howard County Communications that a structure, possibly a barn, was on fire. Chief 3 arrived on location and confirmed that the building, in fact a vacant single family house, was fully engulfed. Chief 3 had the command, and because of the large amount of fire and because the building was vacant, command held the units from Station 3 and returned the rest of the box assignment. Engine 31 protected exposures with two attack lines and extinguished remaining smoldering areas after the fire burned itself out. Tanker 3 was utilized to supply Engine 31 with water, and remaining units from Station 3 assisted with overhaul. Units cleared at 00:24.
