I'm using my credits from not posting on peeps. The discussion points up my contention that regulation of illumination of the means of egress is not clear or particularly user friendly. From NFPA 101, 7.8.1.3 applies to all means of egress during "normal" operation. "7.8.1.3 The floors and other walking surfaces within an exit and within the portions of the exit access and exit discharge designated in 7.8.1.1 shall be illuminated as follows: (1) During conditions of stair use, the minimum illumination for new stairs shall be at least 108 lux (10 ft-candle), measured at the walking surfaces. (2) The minimum illumination for floors and walking surfaces, other than new stairs, shall be to values of at least 10.8 lux (1 ft-candle), measured at the floor. (3) In assembly occupancies, the illumination of the floors of exit access shall be at least 2.2 lux (0.2 ft-candle) during periods of performances or projections involving directed light. " (Note the "designated in 7.8.1.1" is a result of my effort to exclude aisle accessways - what you might call "the row".) My interpretation is these requirements apply to the entire required width of the means of egress. So, if an aisle stair is required to be 36" wide, then for the entire 36" by the entire length an illuminance meter should indicate there are 10 fc minimum. A ramped or level aisle only need be 1 fc and during the event both need only be .2 fc. But my interpretation is that is minimum and is at any point and it must be achieved even in the case of a single lamp failure. (I'd say that he issue Doom raises of a patron kicking out the connection for a multi-lamp aisle light is not tested yet - I don't know if that constitutes "failure of a single lighting unit" as in: "7.8.1.4 Required illumination shall be arranged so that the failure of any single lighting unit does not result in an illumination level of less than 2.2 lux (0.2 ft-candle) in any designated area." This use to be a single bulb but the rise of the Tivoli style light under the aisle arm with multiple sources isn't clearly addressed; i.e. is a single source of 6 a unit or is the entire strip with 6 sources a unit? And the led style....) Emergency illumination of the means of egress - that which is required "in the event of failure of normal lighting" (I can see the court case now where any lamp burnout is construed as "failure of normal lighting") is different. 7.9.2.1* Emergency illumination shall be provided for not less than 11/2 hours in the event of failure of normal lighting. Emergency lighting facilities shall be arranged to provide initial illumination that is not less than an average of 10.8 lux (1 ft-candle) and, at any point, not less than 1.1 lux (0.1 ft-candle), measured along the path of egress at floor level. Illumination levels shall be permitted to decline to not less than an average of 6.5 lux (0.6 ft-candle) and, at any point, not less than 6.5 lux (0.06 ft-candle) at the end of the 11/2 hours. A maximum-to-minimum illumination uniformity ratio of 40 to 1 shall not be exceeded. It uses an "average", a minimum level, and a maximum "uniformity ratio", clearer and more performance based criteria then for "normal illumination" in my opinion. The issue of shadowing from people in the aisle or obscuring from smoke at a higher level is not addressed. Now, the sources for normal and emergency illumination can be the same or different so you could rely on the house lights with transfer to another power source for both. (What else would you do in a ballroom set up "theatre style? Run portable aisle end lights?) Some modern arenas us ellipsoidal spotlights for illuminating aisles and what owner wouldn't rather pay for and maintain 3 or 4 Source 4's in the rafters as opposed to 40 or 50 aisle lights in the seats? While I do usually specify that seat end aisle lights be on emergency transfer, I don't believe it's required. And let's not even talk about flexible spaces and aisle lighting. Oy vey! The runway style lighting - based on my interpretation - is not permitted in place of illumination as it doesn't provide the required illuminance on the walking surfaces - but it is none the less accepted in many jurisdictions. I submitted a proposal 9 or 12 years ago to specifically allow this design but I didn't have the back-up for the luminance levels I proposed. I sought support from the manufacturers of the products and designers who asked for this change but got none. Still a task to be undertaken. Someone added the issue of the so called "panic" switch - a whole other topic I've been known to expound upon - and the requirements in the NEC for emergency lighting (700.20 and 700.21). It's possible you might not find many fully compliant facilities. For instance, any "control switch for emergency lighting " which will de-energize the emergency lighting is not permitted "on a stage or platform" or in the "projection booth".

Because means of egress lighting must be reliable and on emergency power , placing the aisle lighting or any lighting for the egress path on a dimmer is not allowed. However, local code(s) could change any of this - however I would not expect they would allow less than this. Just a side note - covering, blocking, obscuring, reducing the light output (as in putting gel over them) or removing the lamps from exit signs is not permitted. This usually comes up at the same time as aisle lights. In fact, the 101 code states "It is the intent to prohibit a freely accessible light switch to control the illumination of either an internally or externally illuminated exit sign." I would recommend obtaining a copy of the 101 Life Safety Code Handbook - every theatre should have a copy of the current version of this document- current version is 2003.

Well people will have to decide whether they believe "urban legends" or if they want to do things the right way. When we get the rights to perform a show here we are certain that they include archival recording, both audio and video. We also do radio broadcasts so those must be negotiated as well. Our collective bargaining agreements and venue rental contract also include the right to record for archival use. Any designers or other members of the creative team will also have a clause in their contracts about this. And we furthermore define just what "archival recording" means, and the limits of what can be done with such recordings. I know things would be a bit different in a school setting, but if you haven't specifically addressed all these issues then you're probably headed for trouble one day. | Boyd Ostroff | Director of Design and Technology | Opera Company of Philadelphia | http://tech.operaphilly.com | ostroff [at] operaphilly.com ------------------------------ Message-ID: <014D202957F6D8118924000F20D7342B04C5C3AA [at] az33exm01.corp.mot.com> From: Wood Chip-P26398 Subject: RE: "Archival recording" myth debunking Date: Fri, 1 Apr 2005 11:02:44 -0700 In the UK- http://www.theatrelibrary.org/sibmas/congresses/sibmas94/antw_25.html Actor's Equity check 31 c)- http://www.actorsequity.org/Library/rulebooks/Business_Theatre_Rulebook_04-05.pdf Seems to be allowed. -----Original Message----- From: Stagecraft [mailto:stagecraft [at] theatrical.net] On Behalf Of Jon Ares ...and I'm looking for some concrete reference or such that debunks the urban legend/theatre myth that a videotape "Archival Recording" is acceptable.

Is the word of Dramatists' Play Service definitive enough? Here's what their FAQ says: "Q. Our theatre would like to make a videotape for our archives/grant proposal. Is this all right? "A. The agents we deal with are increasingly open to this kind of request, but as usual you must get their permission first. Again, contact the author's agent by writing to them at the address listed on the copyright page of the acting edition." In other words, ask permission from the playwright's agent (not Dramatists' or Sam French) and you *may* be allowed to make an archival tape. But it is never permissible to do so without that permission, unless the play you are taping is entirely within the public domain (Shakespeare, for instance). In my experience, it can take a couple of months or longer for an agent to get back to you, so anyone who wishes to do this needs to plan ahead.

I was looking at it merely from the talent side. You also need the playwright's permission and I suppose all the designers, director, and producer. It is a collaborative effort, after all.

In a union venue you'd better believe you need the permission of the stagehands. You probably should get releases from everyone even in a volunteer or non-union setting, although this may be more along the lines of CYA. And the list goes on and on. If you rented any scenery or costumes then you will also need their permission. Basically, everyone who has rights to any of the intellectual property will need to sign off on this. Is it a lot of trouble? Yes. But it's just part of the procedures involved with running a theatre the right way. In the professional world you will develop templates for the various contracts which contain a paragraph covering all this. Obviously, the larger your company is the more risk you're exposing yourself to if you don't do everything by the book. In a tiny community theatre that operates with volunteers there's probably not a lot of risk. But that doesn't mean you shouldn't do things the right way. And I think the real issue is a good definition of "archival." Does that mean one copy which is locked in a secure place? We have the right to share our recordings with other professionals, but we require them to sign an agreement before sending copies, and they are strictly treated as loans which must be returned within 90 days. The videos themselves contain a "credit roll" that features the full text of this agreement as well. I suspect that "archival recording" is often just a guise for a video of the show which becomes widely distributed to cast members. | Boyd Ostroff | Director of Design and Technology | Opera Company of Philadelphia | http://tech.operaphilly.com | ostroff [at] operaphilly.com ------------------------------ Message-Id: <6.2.0.14.0.20050401135448.01d9ed48 [at] mail.insightbb.com> Date: Fri, 01 Apr 2005 14:00:43 -0500 From: Mike Brubaker Subject: Re: aisle lights In-Reply-To: References: Egress path lighting CAN be on a dimmer, provided that there is a means to drive that light to full in an emergency/power loss (generally, an automatic transfer switch).

This includes actors, designers, the playwright, copyrighted music you are using, etc. Every design contract I've been given from a LORT or AEA house (even an opera company) has a clause in there regarding an archival recording of the show. The opera company even reserved the right to broadcast the archival recording on public radio. This was a clause they would not budge on. So everyone signed it and they got their recording.

Included in the clause for the archival recording was the sentence reserving the right to broadcast. The broadcast thing was more of an issue to the singers, orchestra members, and me as the Sound Designer. Certainly, the Set Designer doesn't care if the set is broadcast on the radio ;) But they put it in everyone's contract just to make sure they covered all their bases.
