"The following suggestions will partially avert such a horror as has been witnessed at the Iroquois, which was advertised as the safest fire-proof theater in Chicago:
"All seats throughout the house should be placed far enough apart from back to back so that an open passageway running from aisle to aisle shall be large enough to allow a person to get out without disturbing all the people seated in the section. In the Iroquois the seats in the gallery are so closely spaced from back to back that one cannot sit in a comfortable position at any time. All seats should be made of iron framework, with seats fixed so that danger of catching clothing on upturned edges may be averted, which in the present theater seats causes very much delay in a rush. The upholstering should be done with asbestos wool and all covering done with asbestos fire-resisting cloth.
"An aisle should be left between the orchestra and the front row of seats. Main aisles should be made so that they connect with the aisle in front, also the aisle in rear, without any obstructions, and an exit door placed at end of each aisle leading directly to the vestibule. The present system is one large door at the center so that people from the side aisles collide with those from the center aisles and no one can get out. It is also very important that the door opening, with doors open, is a trifle larger than the aisle; all seats that face on aisles to be plain to prevent clothing from catching on same.
"Carpets should be prohibited in all halls and aisles and replaced by interlocking rubber tile or some similar covering to prevent slipping in a rush.
"All steps should have safety treads, composed of steel and lead, in place of slate or marble, which becomes slippery and dangerous. Stairs to be straight without winds or turns and at every ten feet from the sidewalk there should be a landing twice as long as the width of the stairs and doors at the foot of the stairs should be a trifle larger than the stair opening.
"All balconies and galleries above the first floor should have a metal hand rail back of each row of seats securely fastened to the floor construction.
"Doors should swing out; in addition to door handle threshold to have an automatic opening device so as to throw doors open in case of fire or accident. Also at each fire exit there should be in view of the audience a box containing saw and tools and plainly marked for use in case of fire, providing locks on doors fail to work. In addition an attendant should be placed at each fire exit and remain there until the house is vacated during every performance.
"Fire escapes should be made of regular stair pattern with treads eleven inches and rises seven inches, and treads provided with steel and lead composition covering and risers closed.
"Instead of sloping the ceiling toward the stage it should be made level with a cone shape toward the center and there connect with a down draft ventilator and an emergency damper controlled by a three-way switch from stage, box office and each balcony, made large enough to form a smoke flue in case of fire. Wires controlling this ventilator should run in conduit fireproofed and in addition to switch an electric emergency switch weighted with a fused link to make a contact when link breaks. Same to apply to stage, halls and stairways, except that fireproof ducts will connect halls and stairs with outer air. In addition to the ventilator every part of the house should be equipped with a system of sprinklers operated automatically by a gravity system. A large glass chandelier such as used at the Iroquois should be prohibited.
"Emergency lights in case of fire and accidents during the performance to light up the house should be placed on ceiling of main auditorium, balconies, halls and stairs and built of fire-proof boxes with wired plate-glass face. These lights should be operated on a separate system and run in fireproof conduits, and controlled from the street front, also to have a fusible weighted switch on stage.
