Ventilation

(i) The building shall be provided with efficient means of ventilation direct to the open air. (ii) Unless the auditorium is air-conditioned the means of ventilation shall take the form of natural ventilation and power-driven exhaust fans suitably located and of adequate size for the purposes intended. (iii) Where natural ventilation is provided by windows of skylights which have to be darkened or obscured, free permanent top ventilation shall be arranged by means of ridge or ceiling ventilators. The clear opening of such ventilators shall not be less than I square foot for every 10 persons that can be accommodated. (iv) There shall be a time gap of not less than twenty minutes between two cinematograph shows. The duration of an interval in a cinematograph show shall be not less than ten minutes. During the gap between two shows and the interval in a show all doors and ventilators shall be kept wide open and all exhaust and other fans will be worked at top speed so that the whole of the auditorium shall be flushed with air completely. Any accident, fire or explosion occurring within the licensed premises which is attended with loss of human life or serious injury to persons or property shall be reported immediately to the nearest Magistrate or to the Officer-in-charge of nearest Police Station and by telegram or telephone where such means of communication are available.
