In June, ANSI's Board of Standards Review has approved three more ESTA standards. One is a new standard, and two are revisions to existing standards. All three are published, and are available for free download from the TSP website at They are also available for sale from ANSI and IHS.

These two standards were approved on June 2:

ANSI ES1.19 – 2020, Event Safety – Safety Requirements for Special Event Structures

This standard – the first published Event Safety Working Group standard – is a revision to the 2018 version, correcting errata, and expanding on existing requirements. It covers structural safety requirements 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. The scope of this standard covers any such structure not otherwise addressed by existing standards, codes or legislation, and to the extent that such other standards, codes or legislation do not already address conditional use of those temporary structures within existing structures.

ANSI E1.4-3 – 2020, Entertainment Technology—Manually Operated Hoist Rigging Systems

This new standard is the third in a set of revisions and partitions to ANSI E1.4-2014. It applies to permanently installed, manually operated hoists used as part of rigging systems for raising, lowering, and suspension of scenery, properties, lighting, and similar loads. This standard establishes
requirements for the design, manufacture, installation, inspection, and maintenance of manually operated hoist systems for lifting and suspension of loads for performance, presentation, and theatrical production.

This standard was approved on June 18:

ANSI E1.47 – 2020, Entertainment Technology—Recommended Guidelines for Entertainment Rigging System Inspections

This standard, a revision of the 2017 version, offers guidance on inspecting entertainment rigging systems, which are systems used to lift and support scenery, luminaires, and other equipment overhead in entertainment venues, such as theatres, video/film studios, amphitheatres, and arenas used for live performances or special events.
