Philadelphia, PA Burnham, Williams and Co Fire, 1907
1907 BURNHAM, WILLIAMS & CO.
Fire started about 5:30 P. M. in third story in a section recently partitioned off for drafting room with no sprinklers. It quickly broke out into main room, where sprinklers by unfortunate oversight were shut off. Pumps and public department were quickly brought into play, but the start gained in the unprotected areas allowed the fire to attain serious headway and large loss resulted. The fire probably came from smoking, as the draftsmen left the room. Its spread was due to lack of sprinklers and to improperly closed valves.
