Shortly after 2100 hrs. units from Company 4 and the surrounding area were alerted for a reported Barn Fire in the 13000 blk. of Frederick Road.  Minutes there after a Task Force and Special Alarms were sounded bringing TANKER 5 to the scene.  TANKER 5 arrived on the scene and was placed into the water shuttle operation as there are no municipal hydrants in Company 4's first due.  As the Special Alarms continued ENGINE Co.  51 eventually ended up on the incident being utilized to establish another drafting site to support the operation.  Units operated for over two before being placed in service, the quarters of Company 5 was staffed with an additional crew.
