Introduction
The object of this document is to provide safety requirements for event structures. Examples of event
structures covered by this standard are, but not limited to, stage roofs, stage walls, stage platforms,
support structures for entertainment technology equipment, technical accommodations, raised
platforms for public and bespoke structures. These safety requirements are aimed to safe-guard persons
and objects against damage caused by design, manufacturing and operation of these structures.
These safety requirements have been drawn up according to past experience and risk analysis. Existing
national rules concerning health and safety of workers remain untouched.
Attentions is drawn to the fact that in certain countries additional/different requirements may be
applicable due to existing national regulations or equivalent.
1 Scope
This document specifies the minimum requirements necessary to ensure the safe design, calculation,
manufacture, assembly, operation, disassembly, inspection and maintenance of the following, but not
limited to:
• structures e.g. stage roofs, stage floors, follow spot towers, PA towers,
• LED support structures,
• one-off event structures,
• hospitality structures,
• temporary spectator facilities.
The above hereafter called event structures are structures intended to be installed and dismantled
specifically for an event.
This document does not cover:
• Spectator facilities – EN 13200-series,
• Temporary structure – Tents – safety by EN 13782,
• Fairground and amusement park machinery and structures as per EN 13814 series,
• Temporary works equipment covered by CEN/TC 53,
• Inflatable play equipment-safety requirements and test methods as per EN 14960,
• Entertainment Technology as described by CEN TC 433.
NOTE This document is not applicable to event structures which are designed, manufactured, placed on the
market or put in service before the date of publication of this document by CEN.
