Squad 33 (with 7) responded on the working fire dispatch to the 200 blk N Pitt St in Carlisle. Upon arrival the crew was split to cover the front and rear of the structure and throwing additional ground ladders and making access through a privacy fence at the rear. First arriving crews made a great stop even with finding fire and smoke in multiple exposures. Squad 33 was committed almost 2 hours. A crew was maintained on Station for any additional calls.
