BSR E1.6-2, Entertainment Technology – Design, Inspection, and Maintenance of Electric Chain Hoists for the Entertainment Industry, covers the design, inspection, and maintenance of serially manufactured electric link chain hoists used in the entertainment industry. The standard is being revised to provide more clarity or requirements. Comments are due no later than 23 December 2019.

BSR E1.20, Entertainment Technology — Remote Device Management over USITT DMX512 Networks, is a revision of ANSI E1.20 – 2010. The standard is being revised to clarify ambiguities, fix bugs, and incorporate some additional features. E1.20 is an extension to USITT DMX512 and ANSI E1.11 that allows for bi-directional communication on the primary data link. This allows a controller to discover RDM-enabled devices on the link, to set starting addresses and other configuration settings, and to request status messages. Comments are due no later than 30 December 2019.

BSR E1.21, Entertainment Technology — Temporary Structures Used for Technical Production of Outdoor Entertainment Events, establishes a minimum level of design and performance parameters for the design, manufacturing, use and maintenance of temporary ground-supported structures used in the production of outdoor entertainment events. The purpose of this guidance is to ensure the structural reliability and safety of these structures and does not address fire safety and safe egress issues. This standard also establishes a reasonable standard for care by providing the minimum acceptable requirements at which temporary structures shall be designed and used. Comments are due no later than 30 December 2019.

BSR E1.23, Entertainment Technology — Design, Execution, and Maintenance of Atmospheric Effects, offers advice on the planning, execution, and maintenance of theatrical effects using glycol, glycerin, or white mineral oil fogs or mists, in theatres, arenas, motion picture studios, and other places of public assembly or motion picture production. The guidance is offered to help effects designers and technicians create effects that can be executed repeatedly and reliably, and so that they can avoid excessive exposure to the fog materials and other foreseeable hazards. The revision includes guidance on developing strategies to maintain an effect over the months or years of a long-running show or an extended motion picture shoot. Comments are due no later than 23 December 2019.

BSR E1.37-5, General Purpose Messages for ANSI E1.20, RDM, provides additional Get/Set parameter messages (PIDs) for use with the ANSI E1.20 Remote Device Management protocol. Comments are due no later than 30 December 2019.

BSR E1.47, Entertainment Technology — Recommended Guidelines for Entertainment Rigging System Inspections, covers the inspection of entertainment rigging systems. Rigging systems may be statically suspended (stationary) (dead hung) equipment, manually operated counterweight sets, manually operated hoist sets, rope and sandbag (hemp) sets, and electric hoist sets (including winding drum hoists, packaged hoists, powered counterweight sets). The document includes inspection of fire safety curtain systems, rigging only. Rigging systems frequently include combinations and variations of rigging types. Comments are due no later than 30 December 2019.

BSR E1.62, Minimum specifications for mass-produced portable platforms, ramps, stairs, and choral risers for live performance events, is a product specification covering serially manufactured portable platforms, stair units and ramps used with those platforms, and choral risers. It also would cover railings provided as fall protection accessories for these units. It would give minimum payload and sideways force handling specifications. It would not cover custom platforms or complete stage systems. Comments are due no later than 23 December 2019.

BSR E1.66, Safety Standard for Followspot Positions Erected for Short-term Use in Entertainment Venues, covers safety requirements for followspot positions in, or on, structures erected for short-term use, and positions not covered by ANSI E1.28. It is applicable to positions located indoors or outdoors. It addresses structural, electrical, and personnel safety requirements associated with them. Comments are due no later than 23 December 2019.

BSR ES1.9, Event Safety – Crowd Management, defines “crowd management,” as distinguished from “crowd control,” provides an overview of crowd management theory and vocabulary, and applies these terms to certain reasonably foreseeable risks that arise during live events. The standard is intended both to identify minimum requirements and to provide questions and suggestions that help event organizers make reasonable choices under the circumstances of their event.  Comments are due no later than 30 December 2019.

BSR ES1.7, Event Safety Requirements – Weather Preparedness, addresses the consideration, development and use of weather planning strategies to mitigate weather-related risks associated with live events and their associated temporary special event structures. Its scope includes both indoor and outdoor events, because both have considerations for attendees. Its scope includes sites not specifically designed for public events, as these too represent unusual or unique circumstances relating to risk assessment and mitigation. Comments are due no later than 23 December 2019.

BSR ES1.19, Safety Requirements for Special Event Structures, addresses structural safety for any temporary structure used for special events (“temporary special event structures”), where such structures are used for presentation, performance, structural support of entertainment technology equipment, audience seating or viewing in conjunction with the event, and regardless if the event is indoor or outdoor. It is being revised to correct errata, and to add further clarity to its scope and requirements. Comments are due no later than 23 December 2019.

BSR E1.21, Entertainment Technology Temporary Structures Used for Technical Production of Outdoor Entertainment Events, is a revision of ANSI E1.21-2013 to deepen the requirements for operations management plans, designated person responsibilities, and related requirements. E1.21 establishes a minimum acceptable level of design and performance parameters to ensure structural reliability, safety, and to establish a reasonable standard of care for temporary special event structures.

And a NEW project:

BSR E1.69, Reporting the Low-End Dimming Performance of Entertainment Luminaires Using LED Sources, shall describe a way of showing the end-user or equipment specifier the low-end dimming performance of LED luminaires, when the luminaire output level is set by a control signal varying over the low-end range from 10% to 0%.  Right now, there is no way for an equipment specifier to see and compare the low-end dimming of a luminaire without actually looking at the unit, and then there is no way to tell another person what the specifier saw without using subjective terms. Marketing terms, such as “theatrical quality dimming” or “dims smoothly to black,” seem to say something, but really have no objective meaning. Interested? Contact Karl Ruling,
