I ask that they shut off the area if at all possible. If not, then I cut the haze and fog. Obviously the show doesn't have the desired look, but it beats having the fire department showing up during the performance and dealing with a promoter that is less than happy.

With haze machines, what are some of the ways you have used to deal with fire/smoke alarm systems in performance areas such as a school gym or auditorium? For example: try to get someone to shut them off, use a certain brand/type of haze, or just hope and pray that they don't go off?

Wow, that is a lot of atmospheric FX. Are any of those machines backups or are they all primary machines?

Currently, our show uses 14x HES F100 DMX foggers, 5x DF50 DMX hazers, 3x LN2 jets, 5x DMX fans, 2x Le Maitre G3000 DMX Foggers,
1x Mammoth LN2 DMX fogger, and a pneumatic fog diverter system with a Strand 550i for control of all devices. (soon to be Grandma) Our atmospherics gear operates a 10 show per week duty cycle, so if anyone would like to chat about reliability, feel free to hit me up.

Robert - Absolutely not. The Martin machine is a water and glycol hazer that has a heat exchanger like most foggers. The DF-50 is a mineral oil machine that uses compressed air. Never the twin shall meet. The trade off is the mineral oil lasts a long long time which stays in lighting equipment. Generally, a glycol based hazer will not leave a residue, but it does not hang as long as oil.

If you use or manufacture fog or haze machines, you'll want to check this out. There's a revised standard out for public review having to do with the design and use of theatrical fog. - Richard

Revised Fog Effects Standard Available for Public Review

BSR E1.23 - 200x, Entertainment Technology - Design and Execution of Theatrical Fog Effects, is available for public review at http://www.esta.org/tsp/documents/public_review_docs.php through June 22. The BSR E1.23 project is a revision of the existing ANSI E1.23 - 2006 standard, which offers advice on the planning and execution of theatrical fog effects using glycol, glycerin, or white mineral oil fogs or mists in theatres, arenas, and other places of entertainment or public assembly. The revision project is (1) to change the list of fog chemicals in the scope to better match those chemicals normally used in theatrical fog effects, and (2) to better define the qualifications of those in charge of designing and executing the effects.

In addition to being asked to review the document to see if it offers adequate advice, reviewers are asked to notify ESTA of any protected intellectual property in the draft standard. 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 by anyone without prejudice or preference for a reasonable fee. Any protected intellectual property should be noted on the public review response form.

Comments must be received by the end of the day UTC on June 22. When June 23 starts, the review is over, and the links on the website to the document, the review form, et cetera will disappear.

Wow! That sounds like a nice thick atmosphere at the flick of a switch. I have a question: For some reason, our property purchased Martin Magnum hazers for our night club. They function fine, but the fluid isn't long lasting enough, and we can go through a pint of fluid in only a few short hours of club action. Can anyone tell me if there is an alternative fluid that I can run through these hazers to get a longer lasting effect? Can I run DF-50 fluid through them? I have DF-50's in the showroom, and I can say that one DF-50 provides more interference medium than 2 Martin Magnum hazers running full blast. Of course the trade off must have been financial. Any ideas?
