scope:

This Standard is intended to be applicable to the creation of theatrical effects using artificial fogs or mists in theatres, arenas, and other places of entertainment or public assembly.

Purpose

The purpose of this Standard is to offer atmospheric effects creators and operators guidance in the planning and execution of theatrical fog effects so that the health and comfort of workers and spectators shall not be compromised by excessive exposure to chemicals and particulates that are the result of the use of such theatrical fog effects. The Standard is also intended to provide guidance related to the obscuration of hazards or paths of egress in the theatre, arena, place of entertainment or public assembly in which the fog effect is produced. In addition, the Standard is intended to help avoid accidental triggering of fire detection and notification systems, while preserving the required functioning of the systems.

To help in offering guidance, Annex A contains explanatory text for some of the clauses in this Standard. Clauses for which explanatory text is available are marked with an asterisk. The relevant clause in Annex A has the same clause number as the text to which it refers, but the clause number is preceded by the letter A to show that it is part of the annex.

Annex A is informative only, and contains no mandatory requirements. If there is any apparent conflict between the requirements of this Standard and the advice offered in Annex A, the requirements of this Standard shall prevail.
