She is familiar with the location of windows and fire escapes, and the location of the fire extinguishers and axes. She knows the position of all stairways, particularly the top landing and scuttle to the roof. She knows where all fire proof doors are located, where the water pails are kept and she can render the firemen great service in directing them to a more advantageous position. All doors should be unlocked so that the firemen can have free access without breaking them in and causing delay. The doors, however, should be kept closed to prevent the fire spreading. The rapidity with which a building is consumed by flames is due to the wind and the draughts from stairways, open doors and windows and elevator shafts. The walls of elevator shafts and all vertical openings should be built of non-combustible material, such as brick and mortar and all elevators should be equipped with automatic traps. In case of a fire on the first floor, the automatic trap would fall when a certain degree of heat was reached and thus prevent the fire from reaching the second floor, and the progress of the fire would be delayed. All fire hose should be tested every six months. A leak may have caused the hose to become worthless. All hose should be attached to the fire plug at all times and the little wrench for turning on the water should be tied to the rack where the hose is kept. All these essentials should be examined and carefully scrutinized by every housekeeper and chambermaid. A fire can make great progress while some inexperienced person is fumbling with and trying to attach the hose and turn on the water. There should be a red light in the hall in front of the fire escape window; a red light can be seen better than a white one. The view of the fire escape window should never be obstructed by any kind of a curtain. All hotels should have a stand pipe, it will reduce the rate of insurance one-third. Although few people know how to escape down a rope fire-escape, every room in the hotel should be equipped with one. All fire departments should have a life net; dropping into a life-net is not so hazardous as sliding down a rope when one is ignorant of the proper way to do it. The life nets are made of woven rope with springs, and are 10 feet in diameter. The firemen hold this net and persons dropping into it can be saved.
