Film Projection

Article 540: Motion Picture Projection Rooms

Article 540 addresses projection rooms. Methods for showing a film are frequently – and increasingly – digital, but historically there has been a significant hazard from the simultaneous presence of flammable film and high-power, high-temperature lighting systems used for projection.

Article 540 addresses, as stated in Section 540.1, "motion picture projection rooms, motion picture projectors and associated equipment for the professional and nonprofessional types using incandescent carbon, arc, xenon or other light source equipment that develops hazardous gases, dust, or radiation."

This article provides the rules for projection rooms that are required for the use of “Professional Projectors” as defined in Section 540.2. These projectors are for use with film. Digital projectors do not fall into this definition, and they are often mounted in the same space as the audience – as they are in some of the large dome theatres – because they do not use film and they do not develop hazardous gases, dust, or radiation.
