Entertainment Technology--Recommended Practices and Guidelines for the Assembly and Use of Theatrical Boom & Base Assemblies
ANSI E1.15 gives advice on boom and base assemblies, simple ground-support devices for lighting equipment and accessories used on stages and in television or film studios. If the assembly is tall, not plumb, loaded unevenly, or likely to get run into by stage wagons or performers, there is substantial risk. This document offers advice to lower that level of risk or eliminate it.
