Since the ABTT withdrew its Code of Practice in view of the HSE’s concerns , much work has been carried out by the theatre industry, not only on Tallescopes but also on other methods for working at height in theatres.  Involved parties were the Theatrical Management Association (TMA), The Federation of Scottish Theatre (FST), the Association of British Theatre Technicians (ABTT), the Ambassador Theatre Group (ATG), the manufacturer of the Tallescope, Aluminium Access Products (AAP) and a number of other theatre organisations from Scotland and Wales.  HSE were also involved.

Original post by HSE and many thanks to them for allowing “I want CHAS” to use and their entry about Health & Safety
