ANSI E1.15 This video is a brief synopsis of ANSI E1.15, which gives advice on boom and base assemblies, simple ground-support devices for lighting equipment and accessories. If the assembly is tall, leaning, loaded unevenly, or likely to get run into by stage wagons or performers, there is substantial risk. This document offers advice to lower or eliminate that risk.
