Last night at 8:21pm the crew from Engine 901 had just finished training when tones dropped for a brush fire in the 2000 blk of Columbia Ave in East Hempfield Twp. Engine 901 arrived first and found a mobile home frame and surrounding brush burning in an abandoned mobile home park. The crew pulled a line and began extinguishing the fire. Chief 901 took command and requested an additional engine. Engine 663 arrived and secured the water supply for Engine 901 and pulled a second line. Engine 671 and Truck 67 arrived and an extensive overhaul began. Crews cleared at 10:30 pm.
