ANSI/ESTA E1.15:2006 pdf download.Entertainment Technology 一 Recommended Practices and Guidelines for the Assembly and Use of Theatrical Boom & Base Assemblies.
C. Guidance to governing, regulatory, or other authorities having jurisdiction in the development and enforcement of safety directlves
Mother wnpo1ant goal of this document is to establish a distinction between manufacturers, assemblers, and users. More importantly, because the user often assumes responsibility and liability equal to that of an assembler or a manufacturer, this document provides information intended to assist in the evaluation and reduction of that risk
Those engaged in the manufacture, assembly or use of any device In the Entertainment Industry have an obligation to provide – and obtain as applicable — complete instruction and training as may pertain to the safe application and use of such devices. Manufacturers are encouraged to support and promulgate the general intent, recommendations and guidetines described herein, particularly with respect to the enhancement of safety awareness among assemblers and users of the devices.
3 Definitions
Assembly (See also D.vlc.) The entire unit; all components fitted, or otherwise attached together to form a complete unit. For the purpose of this document, the terms assembly and “device are used interchangeably. where required to maintain clarity of intent.
Assembler. An individual wiio attaches together components that are designed, selected, or specified by others. in accordance with instructions provided by others, sito complete assemblies intended for use within the scope of this document.
Base The part of the assembly that makes direct contact with the floor, walking or acting surface, and that serves as the primary stabilizing and supporting element for the entire, complete assembly.
Base vertical fitting: The titling, coupling, or other component used to attach the vertical member to the base.
Base weight: Weight placed on. or affixed to, the base and used in addition to the weight of the base itself to provide additional stability to the system.
Competent person: A person who is capable of identifying existing and predictable hazards, and who is authorized to take prompt corrective measures to eliminate the hazards.
Design factor: A ratio of the working load limit to the ultimate breaking strength of a material or component.
Device (See also Assembly): The entire boom and base assembly, as intended for use in accordance with, and within the scope of. this document.
Dynamic load A load applied to a device or assembly that changes with time, and is the result of motion or mipact.
Fixture: Any equipment intended for attachment to the boom & base assembly.
Horizontal attachment fitting: The fitting, coupling, or other component used to attach the horizontal member to the vertical member.
Horizontal member: The part of the assembly that is mounted perpendicular to the vertical member in the horizontal plane, parallel to the floor, and to wtiich equipment may be attached.
Manufacturer: Any qualified person, organization, or entity that either a) builds components from raw materials. or b) designs, selects, or specifies individual components, intended for assembly together into complete devices. and intended for the specific applications described herein.
Qualified Person: A person who, by possession of a recognized degree or certification of professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subIoct matter or work.
Shal[ Indicates a mandatory and required action.
Should Indicates a recommended action, not necessarily mandatory.
User: An individual who attaches loads to or otherwise uses the fully assembled devices described herein, but does not necessarily manufacture or assemble them.
Vertical member: The specific part of the assembly that is fixed or fastened to the base, extending vertically, and that provides the primary vertical extension to the whole assembly. The term may refer to a single fixed length designed to provide a fixed height, or multiple sliding lengths designed to provide variable heights.
4 Purpose.1 Acceptable Uses
The following applications of the devices described herein shall be considered acceptable, and within the scope of this document:
A. Mounting of single fixtures, the weight of which does not exceed 35% of the total assembly weight, or
B. Mounting of small quantities of fixtures, the total combined weight of which does not exceed 50% of the total assembly weight AND where the weights of which are as evenly distributed about the vertical member as is feasible.
