ESTA E1.21 [ Revised ]

Scope and intent

The temporary structures within the scope of this document shall be limited to those dedicated to the technical production of outdoor entertainment events. General public access temporary structures, such as food vendor tents, portable toilets, and other portable temporary structures for directly serving the audience or attendees at outdoor entertainment events, are not included in the scope of this standard. Custom temporary structures supporting performance platforms are included in the scope of this document. This document does not include pre-engineered, manufactured, modular staging systems used as platforms for performance, independent of other temporary structures.

This document 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.

The intent of this standard is to establish a reasonable standard for care by providing the minimum acceptable requirements at which temporary structures shall be designed and used.
