As Waldorf Volunteers handled two working fires (the Squad was on a Baden House Fire and Engine 31 was on a Commercial Building Fire in the Bannister section of St.Charles) Engine Company 14 and Engine Company 2 were alerted for the fill-in at Station 3. Engine 143 marked up with a total of 6 under command of the Captain (J.Vermillion). While enroute to Fire 3, Engine 22 was sent to set up the Landing Zone for a Motor Vehicle Accident. Engine 143 remained at station 3 for just about three hours before returning back to Quarters. Engine 143 had no calls while filling in.
