Right around 1030 hours Water Witch was requested for an Ambulance as part of the house fire assignment in the 600 box. A791 and EMS Chief 7 responded and handled rehab. Shortly after, dispatch alerted us for an engine to the scene which Engine 72 (4) handled. Once on the scene the crew assisted with extinguishment and checked the exposure. The company was then alerted to transfer an engine to Perry Point (career) Station 11. Engine 7 (6) covered 11’s area for approx 3 hours. IV792 transferred to Station 6 and handled a medical box in 6’s area. Engine 73 (5) transferred to Station 72 during the incident. Tower and Tanker 72 were also staffed at 72 along with Engine 73. All Water Witch units were back in our Stations by 1500.
