Twelve Rescued in Apartment Fire Twelve persons, three of them women, were carried down ladders to safety recently by San Francisco truckmen when fire swept a three-story downtown apartment house at 51-55 Russ Street. When firemen arrived in response to Box 2251 at Sixth and Mission Streets, men and women were hanging out windows crying for help and some were about to leap to the cement paving below when firemen quickly raised ladders and carried the trapped ones to safety. Cause of the blaze was undetermined. Asst. Chief Engineer Martin J. Kearns termed the damage as “considerable.” The two-alarm blaze apparently started in a stairwell and raced up to the top floor, cutting off escape of third-floor occupants. The flames were fed by escaping gas from meters which exploded shortly after the fire started. None was injured in the fire, which attracted a large crowd from nearby downtown streets.
