Weather vs. Lighting Designer
Posted on Monday, March 30th, 2015
Written by: John Featherstone
Even if Oscar Wilde did once say “Conversation about the weather is the last refuge of the unimaginative,” we all still love to talk about the weather. And, sooner or later, we will all have to do a show outside, or at the very least in a tent.
If we are honest, we are a business of “control freaks.” We love to set our own schedules, create our own environments and make our own rules. Yet the weather won’t cooperate with our schedules, seems to conspire against our creativity, and defies our rules. Whatever the reason, there is little debate that the weather is changing — storms seem to be fiercer, winds stronger, rains harder, winters colder and summers hotter. We have all seen the results of the weather catching us off guard, some of us first hand. From festival roofs collapsing to tour bus accidents, all too often lives are lost or people seriously hurt – band, crew and audience alike. So how can we learn to work with the weather, and still stay sane and most importantly safe? I’d like to use two projects as examples of how planning helps work in the face of the elements and coming out if not ahead, certainly unscathed.

Two PLASA Standards Published: A Revision and a Reaffirmation
Posted on Friday, February 27th, 2015
NSI E1.19 – 2015, Recommended Practice for the Use of Class A Ground-Fault Circuit Interrupters (GFCIs) Intended for Personnel Protection in the Entertainment Industry and ANSI E1.23 – 2010 (R2015), Entertainment Technology – Design and Execution of Theatrical Fog Effects, were approved by the ANSI Board of Standards Review on February 10th and 13th respectively. They are now published and are available for free at http://tsp.plasa.org/freestandards. The free download is made possible by the sponsorship of ProSight Specialty Insurance. They also may be purchased from ANSI’s eStandards Store (http://webstore.ansi.org/) for $15.00 each.
ANSI E1.19 is intended to offer guidance in accordance with existing applicable standards on how to select, install, use, and maintain ground-fault protection devices in the entertainment industry to protect persons from shock and persons and property from fire. This is a revision of the 2009 version that incorporates new information about avoiding nuisance tripping and offers new recommendations for ground-fault protection on higher ampacity circuits.
ANSI E1.23 offers guidance on planning and carrying out fog effects so that recognized exposure levels are not exceeded, fire and egress hazards are not created, false alarms don’t summon the fire brigade, and fog effects are executed as they are designed, performance after performance. This is a reaffirmation of the 2010 version. There are no substantive changes.

Four New Technical Standards Program Projects Announced
Posted on Tuesday, August 12th, 2014
The PLASA Technical Standards Program announces four new projects.
BSR E1.37-4 File Transfer Control to Provide Firmware Upload Capabilities — The proposal sets out the minimum requirements for controllers and responders to allow a method of firmware uploads using RDM. It defines the transfer process, command implementation, and relationship to the existing ANSI E1.20 RDM standard, and specifically provides a transfer mechanism that can be applied to memory limited responders with transmit and receive buffers as small as 64 bytes, while allowing scalable improvements (reduction in transfer times) for responders.
BSR E1.54 PLASA Standard for Color Communication in Entertainment Lighting — The goal of this draft standard is to specify a standardized color space by defining an RGB triangle and white point. Using these, manufacturers of luminaires and lighting controllers will have a common reference toward achieving consistent color. The standard will facilitate the communications between lighting controllers and color-changing luminaires by using this standardized way of specifying color. The method proposed is generic and is neither manufacturer-specific nor color technology-specific.
BSR E1.55 Standard for Theatrical Makeup Mirror Lighting — The standard would offer recommendations and requirements for makeup mirror lighting in performer dressing rooms and similar locations. It would define a range of acceptable lamp CCTs and color-rendering ratings, and would also specify illumination levels and lighting angles for illuminating the performer’s face.
BSR E1.56. Rigging Support Points Design, Fabrication, Installation, and Testing — This standard is to provide guidance for the design, fabrication, installation, and testing of permanent and temporary rigging points and rigging lugs and their connection to existing building and venue structures.
PLASA invites any interested parties to become involved with these projects, either by joining a working group or participating in future public reviews of draft standards. Working group applications may be downloaded from http://tsp.plasa.org/tsp/working_groups/index.html and public review documents are posted to http://plasa.me/4xvjf.
