Section 23 in Bihar Cinemas (Regulation) Rules, 1974
23. Electrical installation.
(1)The whole of the electrical installation in the licensed premises shall comply in all respects with the Indian Electricity Rules, where these apply and with the rules of the Calcutta Fire Assurance Association.(2)All switches and fuses and all electrical apparatus liable to become hot, installed in the projection room shall be placed as far as practicable from any place, where cinematograph film is stored or handled, and shall be so projected that the cinematograph film cannot come in contact with any heated area.(3)Where switch-boards are installed in the projection room, the space between any switch board and the wall shall be enclosed with fire proof material in such a manner that a fire cannot spread to the wiring at the back of the switch-board.(4)All resistances for the cinematograph machines shall be placed inside the projection room. They shall be mounted on incombustible bases and shall be so projected and placed at such a distance from any combustible material that no part of the resistance, if broken can fall on such material, or vice versa.(5)Conductors from any switch-board in the projection room to the cinematograph machine shall be enclosed in screwed conduits and shall terminate in a suitable terminal box. Conductors from such box to the lamp shall be covered with flexible metallic tubing or braiding mechanically connected to the terminal box. Such conductors shall be controlled by an efficient double pole switch mounted on a switch-board within the projection room. There shall be one double pole switch for each projector and it shall be conveniently placed near the projector.(6)In the enclosure the maximum potential difference shall not exceed 240 volts, provided that this restriction shall not apply to any amplified pressures in the amplified and sound system.(7)Where an electrical metal filament project lamp of the vacuum or gas filled type is used in the cinematograph machine, it shall be adequately ventilated and the potential difference within the enclosure shall not in any circumstance exceed 240 volts.(8)All switch-board shall be constructed wholly durable non-inflammable, non-absorbent material. The various live parts shall be so arranged by suitable spacing or shielding non-ignitable insulating materials that cannot be maintained between any such parts or between such parts and earth.(9)All fuses shall be provided with a suitable incombustible and insulating carrier of such a form as to project a person handing in from shock and burns and contracts shall be provided on the carrier to which the ends of the fuse can be readily attached.
