  • 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.
