Regulation, safety rules and the documents you will need
The craft here lies at the intersection of technology, people, and large events. Therefore there are both rules about the training itself and rules about how the work may be performed when you're faced with the tasks in reality.
Vocational education as a theatre, event and AV technician is set out in a regulation — i.e. an official set of rules that describes the purpose of the education, its stages and specialisations and the objectives you must achieve along the way. The regulation stems from legislation on vocational education and it is the professional committee for the area that helps keep the content up to date with what the industry needs.
When you stand at a concert or fair the regular rules for working environment and safety at a workplace apply — even though the workplace today is a festival site and tomorrow a theatre stage. It's especially about working safely with electricity lifting and rigging heavy equipment at height and with large amounts of audience.
As a technician you connect equipment to power daily but there is a limit to what electrical work requires authorisation. Certain tasks — for example fixed electrical installations — may only be performed by or under an authorised electrician. As a technician it is therefore important you know the difference between what you can do yourself and what requires an authorised professional.
Beyond the journeyman certificate itself many in the industry get a number of shorter courses and proofs because they are necessary for specific tasks. Which you get depends on your speciality and your workplace.
“Most of it is about knowing what you can do yourself — and when you need to get a professional.”
