It needs your help to continue.  

April 29, 2014 - E-Cigarettes Are Not Atmospheric Effects

E-cigarettes are gaining favor as substitutes on stage for real cigarettes. It could be argued that e-cigarettes are safer than real cigarettes, or even herbal cigarettes, in that the fire hazard is much less and there are no weird products of combustion. However, it is possible that an actor smoking an e-cigarette is exposed to glycol or glycerin levels that exceed the ceiling limits in ANSI E1.5 and Equity contracts. Research is needed on the health effects of short but concentrated exposures to glycol and glycerin fogs as a result of smoking e-cigarettes. Until that research is done and available for evaluation, PLASA neither recommends nor condemns the use of e-cigarettes on stage. At the Fog & Smoke Working Group's 28 March 2014 meeting, it was decided that e-cigarettes should be considered hand props, not atmospheric effects, and therefore are outside the scopes of PLASA's Fog & Smoke Working Group, the Fog Testing Program, and the Fog Stewardship Program.

March 28, 2014 - North American Plugfest in July
The PLASA Control Protocols Plugfest, the event where manufacturers and developers can test their products for interoperability with other manufacturer’s products, is scheduled to take place July 25 through 28, 2014, at the Marriott Solana in Westlake, Texas. The Plugfest was created originally to support the Remote Device Management protocol (ANSI E1.20) but it has expanded to cover all the PLASA Control Protocol Working Group's protocols, including the popular ANSI E1.31 Streaming DMX over ACN protocol, and now a draft version of RDMnet (BSR E1.33). In the past, Plugfest attendees from all over the world have brought controllers, dimmers, luminaires, analyzers, and various other tools and devices, and connected them all through a network to look for and to resolve problems; they will do the same this coming July. Complimentary coffee and snacks are served. There is no fee for participating in this North American Plugfest.

February 09, 2012 - Indiana DOL References ANSI E1.21

On February 8, the Indiana Department of Labor announced the citations it has issued related to the Indiana State Fair stage collapse, which occurred on 13 August 2011. Links to the press release, the three safety citations, a recording of the press conference, and various other supporting documents are available on the Department of Labor website at http://www.in.gov/dol/2367.htm. Complete scans of the official "Safety Order and Notification of Penalty" documents issued against Mid-America Sound Corporation, IATSE Local 30, and the Indiana State Fair Commission are provided. Failure to follow the requirements of ANSI E1.21 is a major part of the findings. The efficacy of the consensus standard's inspection requirements is noted at about the 51-minute mark in the press conference audio recording.

January 31, 2012 - New PLASA Standards Published In January 2012
Four PLASA standards have been published in January 2012:

August 15, 2011 - PLASA Deeply Saddened by Sugarland Concert Accident
PLASA is deeply saddened by the accident in Indiana at the Sugarland Concert. We cannot comment on the specifics of what happened there. We simply do not know the details of what happened, and understand that there are ongoing investigations into what caused the collapse and the response to it.

December 30, 2010 - Two Control Protocols Standards in Review for Reaffirmation
ANSI E1.3, Entertainment Technology - Lighting Control Systems - 0 to 10V Analog Control Specification, and ANSI E1.27-1, Entertainment Technology-Standard for Portable Control Cables for Use with USITT DMX512/1990 and E1.11 (DMX512-A) Products, are announced as being in public review for reaffirmation from now through the end of February 2011. The intention of the Control Protocols Working Group at this time is to reaffirm the existing standards as they are, but this is, of course, contingent on any objections or comments that the public might offer. The public review forms are accessible at http://tsp.plasa.org/tsp/documents/public_review_docs.php. The standards themselves are being sold by The ESTA Foundation at http://www.estafoundation.org/pubs.htm at their normal prices

December 09, 2010 - New Project to Draft a Safety Standard for Stage Lifts
ESTA has started work on a new project to write an American National Standard: BSR E1.42 – 201x, Entertainment Technology – Installed Stage Lift Safety Standard. Stage lifts, such as orchestra pit or theatre forestage lifts, are not the subject of any current national standard. As result, safety requirements and inspections of them are inconsistent. This project is to develop a standard for stage lifts that can be referenced by the International Code Council and the National Fire Protection Association. The scope is limited to safety and to lifts that are installed as a part of the building and that are not for a single theatrical production. Any person involved in the design, manufacture, use, or inspection of stage lifts and who is willing to actively work on the project is invited to join the new working group. A working group application form is available on the ESTA website at http://www.esta.org/tsp/documents/procedural_docs.html.

September 28, 2010 - One New, One Revised

On Monday, 20 September 2010, the ANSI Board of Standards Review approved ANSI E1.30-4 - 2010, EPI 26 Device Description Language (DDL) Extensions for DMX512 and E1.31 Devices, and ANSI E1.23 - 2010, Entertainment Technology - Design and Execution of Theatrical Fog Effects. ANSI E1.30-4 is a new standard, an EPI that recommends a way of controlling a DMX512 device using ACN. ANSI E1.23 - 2010 is a revision of the existing ANSI E1.23 - 2006 standard. The changes clarify the chemicals that may be in fog effects covered by the standard and who is responsible for planning and executing the effects. The two standards should be available before LDI 2010. ANSI E1.30-4 will be a free standard, available for download from the listing of standards on the ESTA website. ANSI E1.23 will be sold through The ESTA Foundation.  

June 23, 2010 - ACN Revisions to Review
BSR E1.17 - 201x, Entertainment Technology - Architecture for Control Networks, has been posted for review at http://www.esta.org/tsp/documents/public_review_docs.php. The draft standard is a suite of documents that revise sections of the existing ANSI E1.17 - 2006. The revisions include changes to the Device Description Language, the Session Data Transport protocol, the Device Management Protocol, and to various EPIs.The revisions are being done to correct errors and to add additional functionality to the standard. The official ANSI review runs from July 9 through August 23, but the documents are available now, and public review responses will be accepted if they are early—but not if they are late. The review is over when August 24 starts. Responses must be sumitted before then to be considered.

June 11, 2010 - Free Boilerplate_For_Specifiers Available
ESTA_Boilerplate_For_Specifiers.txt provides cut-and-paste text as a convenience for people writing specifications and wishing to reference in those specifications standards developed in ESTA's Technical Standards Program. Use of this text will reduce the probability of undesired equipment or installation practices being offered in response to a bid request or a call for proposals because a standard describing the equipment or installation practice was referenced imprecisely. This document of recommended cut-and-paste text will be revised as new standards are published and older ones are revised or reaffirmed, and as better text specifying the standards is written.

May 27, 2010 - Additional RDM Messages to Review

A new draft standard for public review has just been posted: BSR E1.37-1, Additional Message Sets for ANSI E1.20 (RDM) --Part 1, Dimmer Message Sets. The document is in public review at http://www.esta.org/tsp/documents/public_review_docs.php through 26 July 2010. The review is over when July 27 starts. 

April 20, 2010 - New Photometrics Working Group Project--LEDs
The Photometrics Working Group and the Technical Standards Committee have approved a new project: BSR E1.41 – 201x, Recommendations for the Measurement of Entertainment Luminaires Utilizing Solid State Light Sources. The project is needed because current methods for luminaire output measurement assume the use of broad-band emitters. The introduction of narrow-band emitters, such as LEDs, subverts this assumption. The entertainment industry needs measurement methods that are accurate and that take into consideration the industry's need for unusually precise color characterization. The proposed standard will have two parts: the first will be for measuring white light; the second will be for measuring colored light.

January 31, 2010 - New Dust Project
he Fog and Smoke Working Group has started work on a new project: BSR E1.40-201x, Recommendations for the Planning of Theatrical Dust Effects. A wide variety of products are used to create dust effects in entertainment productions. The effects are most commonly used in motion picture and television production, where, for example, a bag of fuller's earth might be placed on top of an explosive charge to enhance the smoke and debris from the blast. However, they are also used in theatrical productions and within theme parks. The use of dust as an aerosol raises concerns for hazards such as combustibility and health effects from inhalation or ingestion, which, although well known in some sectors of the industry, are poorly understood in others. This document would provide recommendations for how to assess the safety of such effects and to plan their use so that the risks are acceptably low.

October 27, 2009 - The Future of Entertainment Networked Control
The ESTA-sponsored Connectivity Pavilion will be on display at LDI 2009 in Orlando, FL in Booth #1349, with an expanded array this year of equipment running the latest in entertainment control protocols. The Pavilion offers a hands-on demonstration of devices interfacing under RDM (ANSI E1.20), ACN (ANSI E1.17), and Lightweight Streaming of DMX512 over ACN (ANSI E1.31). Members of the Controls Protocols Working Group and the task groups for these standards will be in the Connectivity Pavilion to demonstrate and discuss these ANSI protocols, which can be specified for new lighting systems or for upgrades of old ones. Anyone with an interest in lighting control is invited to stop by and see the reality of these protocols and how transparently they allow the operation of equipment from a variety of manufacturers.

October 16, 2009 - Five New ESTA Standards Now Available
On 14 September 2009, ANSI's Board of Standards Review approved four new ESTA standards and the revision of a fifth. ANSI E1.5, E1.27-2, E1.29, E1.30-3, and E1.30-7 are now available for purchase or free download on The ESTA Foundation publications sales website at http://www.estafoundation.org/pubs.htm.

September 23, 2009 - 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 9 November 2009. 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. 

August 25, 2009 - Two New Rigging Projects

At its July 18 meeting ESTA's Rigging Working Group approved the initiation of two new projects:

  • BSR E1.38 - 20xx, Temporary Ground-Supported Structures Used to Support Equipment in the Production of Outdoor Entertainment Events, Excluding Stage Roofs
  • BSR E1.39 - 20xx, Entertainment Technology – Recommendations for the Use of Fall Protection on Temporary Suspended and Ground-Supported Structures

August 21, 2009 - Revised RDM Available for Review

BSR E1.20 - 200x, a revision of the existing ANSI E1.20 - 2006, Entertainment Technology -- Remote Device Management over USITT DMX512, is available for public review on the ESTA website through October 19, 2009. The draft standard and its supporting public review materials are available at http://www.esta.org/tsp/documents/public_review_docs.php.

April 13, 2009 - Standard to Measure Floor Slipperiness Now Available
ANSI E1.34 - 2009, Entertainment Technology - Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues, is now available from The ESTA Foundation. The new standard describes a very simple drag-sled for measuring the slipperiness of a performance floor, and two procedures to use with the sled. One uses standardized stainless steel feet on the sled to give a coefficent of friction number that can be used to describe the floor in a general way. The second procedure measures the slipperiness with a performer's shoe sole materials.

January 20, 2009 - New Edition of DMX512-A Is Now Available
ANSI E1.11 - 2008, Entertainment Technology - USITT DMX512-A, Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories, is now available for purchase from The ESTA Foundation. The path to the document starts at http://www.estafoundation.org/pubs.htm. The list price is $40; member and quantity discounts are available.

May 23, 2008 - Banning the Incandescent Lamp: A Position Statement from the Technical Standards Committee of the Entertainment Services and Technology Association.
As the costs of fossil fuels have increased and the negative effects on the environment from extracting and burning these fuels have become obvious, there have been numerous proposals to ban the incandescent lamp. While ESTA appreciates the importance of saving energy and protecting the environment, we urge caution and suggest that broad bans of any technology only be enacted after careful consideration of the consequences. Incandescent lamps can be replaced in some applications by more efficacious sources. In those cases, people should be encouraged to use the more efficacious sources, thus reducing energy costs for them, and helping to protect the environment for all. However, for some applications, particularly some in stage, studio, and cultural event lighting, there are no suitable replacements for incandescent lamps. They will need to be part of the available lighting technology until such time as more efficacious sources that deliver the same benefits are available.

September 21, 2007 - Draft DMX512 Cabling Standard Available for Review

BSR E1.27-2, Entertainment Technology - Standard for Permanently Installed Control Cables for Use with ANSI E1.11 (DMX512-A) and USITT DMX512/1990 Products, is available for public review through November 19, 2007. The draft standard describes the types of cable to be used in permanent installations to interconnect lighting equipment that comply with ANSI E1.11-2004 (DMX512-A) or with USITT DMX512/1990. The description includes definitions of acceptable cable and connector types and the ways in which they may be used. The draft standard and its supporting public review materials are available at http://www.esta.org/tsp/documents/public_review_docs.php.

August 16, 2007 - New Powered Rigging Standard Project: Electric Chain Hoist Control
The BSR E1.6 project to develop an American National Standard for powered theatrical rigging systems has a new project and part to the standard: E1.6-4, Control of Serially Manufactured Electric Chain Hoists Used in the Entertainment Industry. The E1.6 document has been broken into parts to facilitate its development and to better match the expertise of the people writing it. This newest part is an offshoot of the BSR E1.6-3 project, Selection and Use of Serially Manufactured Electric Chain Hoists in the Entertainment Industry. That project is to specify how chain hoists can be used safely in entertainment applications, which are very different from the applications for chain hoists in factories and materials handling situations. It has became clear that chain hoist control system safety is a complex topic, so the Rigging Working Group, at its meeting on 13 July 2007, voted to give control systems their own E1.6 part and development project.

August 16, 2007 - ANSI E1.11-2004 Revision Project Started
The Controls Protocols Working Group has started work to revise ANSI E1.11-2004, Entertainment Technology--USITT DMX512-A, Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories. The work at this time is focused on correcting errors in the published standard and rewriting difficult sections of text that have been shown to be confusing to readers who do not have American English as their native language. Most of the errors are clearly typographical or cut and paste errors, but correcting them may be considered making substantive changes to the document.

July 10, 2007 - BSR E1.6-2, Chain Hoist Standard, Available for Review
BSR E1.6-2, ESTA's draft standard for electric chain hoists used in the entertainment industry, is available for public review. Check it out at http://www.esta.org/tsp/documents/public_review_docs.php.

June 03, 2007 - Two Draft Electrical Safety Standards Available for Review Through July 30
Two draft electrical safety standards are available for public review on the ESTA website through July 30. The draft standards offer guidance on the use of GFCIs and the inspection for maintenance of stage and studio luminaires. The documents can be accessed at http://www.esta.org/tsp/documents/public_review_docs.php.

January 26, 2007 - A New Old Project Started for Ballast Cables
At its meeting on Friday morning, 19 January 2007, the Electrical Power Working Group voted to start the process of reaffirming ANSI E1.16 - 2002, Entertainment Technology – Configuration Standard for Metal-Halide Ballast Power Cables. The document describes a standardized grounding contact assignment for detachable power cables on 6kW, 12kW and 18kW metal-halide lamp ballasts for portable studio luminaires that use the MIL-C-5015 connector with #28-6 insert configuration on the ballast end of the power cable. In a nutshell, it says that contact A shall be used for the protective grounding contact. This advice, if followed, avoids the problems that can result when a power cord that uses A for power is plugged into a ballast that uses A for ground. (It's been done.) The standard is available on the ESTA website for free at http://www.esta.org/tsp/documents/published_docs.php.

December 06, 2006 - ANSI E1.17 - 2006, ACN, Is Now Available
ANSI E1.17 - 2006, Entertainment Technology - Architecture for Control Networks, better known as ACN, is now available for sale on The ESTA Foundation website. ACN is a suite of documents that specifies an architecture, including protocols and language, which may be configured and combined with other standard protocols to form flexible, networked audio, lighting, or other control systems. It can be implemented on networks that support UDP, IP, and related protocols. It is not bound to Ethernet as a transport medium, but Ethernet is an obvious choice.

November 09, 2006 - Draft Control Cabling and Hoist Standards Available for Review Through Christmas
BSR E1.27-2, Entertainment Technology—Standard for Permanently Installed Control Cables for Use with ANSI E1.11 (DMX512-A) and USITT DMX512/1990 Products, is available for public review through 25 December 2006. The draft standard describes the types of cable to be used to interconnect products that comply with ANSI E1.11-2004 (DMX512-A) or with USITT DMX512/1990 in permanent installations. The description includes definitions of acceptable cable and connector types and the ways in which they may be used. The draft standard and its supporting public review materials are available at http://www.esta.org/tsp/documents/public_review_docs.php.

October 31, 2006 - E1.3 Analog Reaffirmed, E1.17 ACN Approved
On Friday the Thirteenth of October 2006, the ANSI Board of Standards Review approved the reaffirmation of ANSI E1.3-2001, Entertainment Technology—Lighting Control Systems—0 to 10V Analog Control, making it the R2006 version of this control scheme. Six days later, on October 19, the Board of Standards Review approved ANSI E1.17-2006, Entertainment Technology - Multipurpose Network Control Protocol Suite, better known as ACN: Architecture for Control Networks. Both will be published in the next few weeks. The new ANSI E1.3, being a reaffirmation, has no substantive changes, so the new version will only differ from the 2001 version in its note that it is a reaffirmation and in the listing of working group members. ANSI E1.17 is a new standard that is a suite of more than a score of documents, some of which are hyperlinked to each other. It will take more work to prepare for publication, but absolutely minimal formatting changes are expected to be made to the documents that were offered to the public in the last review, which should shorten the preparation time. The biggest change and most pervasive change to the E1.17 documents will be adding the approval date on which it became an American National Standard to each of the documents in the suite.

December 09, 2005 - Six New ESTA Technical Standards Program Projects
The working groups meeting at the Rosen Plaza Hotel in Orlando during the week of the LDI trade show, from the 9th through the 12th of November 2005, approved the initiation of six standards projects. ANSI requires that the initiation of projects be announced far and wide to affected parties so that people can be aware of the projects and can participate if they wish or can argue against the projects being undertaken if they are not needed or conflict with existing standards. People interested in working on a project (besides simply commenting during public review, which also is helpful) need to join the working group for the project. Information about joining working groups and about the need for voting members in under-represented interest categories in the groups is available at http://www.esta.org/tsp/news/newsdetails.php?newsID=153. People wanting to argue against a project being undertaken can write to standards@esta.org to express their concerns.
