Four draft standards are available for public review on the ESTA website through 26 May 2008. All can be downloaded for free at http://www.esta.org/tsp/documents/public_review_docs.php. The draft standards address specific problems found in powered rigging, electrical power distribution, and floors used in live performances and special events.
BSR E1.6-2 - 200x, Entertainment Technology - Purpose Designed Serially Manufactured Electric Chain Hoists for the Entertainment Industry, is part of the BSR E1.6 powered theatrical rigging systems project. This document, BSR E1.6-2, covers the design, inspection, and maintenance of serially manufactured electric chain hoists having capacities of two tons or less and used in the entertainment industry as part of a performance or preparation for a performance.
BSR E1.18-1 - 200x, Standard for the Selection, Installation, and Use of Single-Conductor Portable Power Feeder Cable Systems for Use at Less than 601 Volts Nominal for the Distribution of Electrical Energy in the Entertainment and Live-Event Industries, is part of a larger E1.18 project to offer guidance on portable power feeder cable systems.
BSR E1.19 - 200x, Recommended Practice for the use of Class A Ground- Fault Circuit Interrupters (GFCIs) intended for personnel protection in the Entertainment Industry, recommends practices for the safe use of 100 amp or lower, 120-240 VAC, single or three-phase, 60 Hz Class A Ground-Fault Circuit Interrupters (GFCIs) for personnel protection in film and video productions, theatrical productions, carnivals, circuses, fairs and similar events in North America.
BSR E1.34 - 200x, Entertainment Technology - Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues, describes a means of measuring and specifying the slipperiness of floor surfaces used by performers in live entertainment venues. The slipperiness of a stage floor or dance floor is a concern to performers, directors, choreographers, designers, stage managers--almost the whole production team--but there is at this time no good way to objectively describe the slipperiness of a performance floor.
