Platform size, door size and location shall be suitably arranged to accept a stretcher twenty-three inches wide by six feet, five inches long without tipping, lifting or other abnormal movement. An elevator car with a clear inside dimension of six feet, eight inches wide by four feet, three inches front to back with single slide doors of two feet, ten inches or more in width will meet this requirement.
   (b)   One elevator in every building which shall be designated by the Fire Prevention Officer or Fire Chief shall be equipped with a key lock switch on the ground floor to remove such elevator from automatic service and return it to the ground level immediately for manual operation by the Fire Division.
   (c)   A key-operated lock switch shall be provided adjacent to the elevator at the street floor landing and at other landings subject to the discretion of the Fire Prevention Officer or Fire Chief.
   (d)   The key-operated lock switch shall, when operated, cancel existing car calls, prevent registrations of further car calls, prevent the opening of the elevator doors except at the landing at which the switch is located and cause the cab to travel to that landing, bypassing other landing calls.
   (e)   When the elevator car arrives at the firemen's landing, the doors shall open and remain open until they are closed by the operator of the elevator from the car.
   (f)   The key lock switch to be used both in the elevator car and at the various floor levels as may be specified shall be manufactured by the Chicago Lock Co., lock model number 2174-2 and key number C 2136, or equivalent.
   (g)   All elevators equipped with photoelectric tube devices, which control the closing of automatic, power-operated elevator doors, shall have a switch located in the elevator car which, when actuated, will render the photoelectric tube device ineffective.
   This switch shall be of the constant pressure type, requiring not less than ten pounds nor more than fifteen pounds of pressure to actuate. It shall be located not less six feet nor more than six feet, six inches above the car floor and shall be in or adjacent to the operating panel. The switch shall be clearly labeled "Emergency Switch to Close Doors."
   (h)   Each elevator cab shall have an emergency light to provide adequate light within the elevator car when the primary power fails.
   (i)   Each elevator cab shall be equipped with an emergency bell actuated by an emergency switch inside the cab, which shall be supplied with a source of emergency power so the bell may be actuated when the primary power fails.
