BSR E1.22, Entertainment Technology - Fire Safety Curtain Systems, is available for public review on the ESTA website through March 28, 2006. The draft standard describes the materials, fabrication, installation, operation, testing, and maintenance of fire safety curtains and fire safety curtain systems used for theatre proscenium opening protection.
It is a serious attempt to avoid offering a cook-book description of a fire safety curtain system and, instead, to specify how a fire curtain shall perform. Therefore, it doesn't tell what kind of fabric to use for a fire safety curtain, for example, but instead tells the strength necessary for the fabric and what abrasion and fire tests it must pass.
Readers are asked to review the document for adequate and correct advice and to look for protected intellectual property in the draft standards. ESTA does not warrant that its standards contain no protected intellectual property, but it also does not intend to adopt any standard that requires the use of protected intellectual property, unless that property is necessary for technical reasons and can be licensed and used by anyone without prejudice or preference for a reasonable fee. Any protected intellectual property in the document should be pointed out in the public review comments.
