Anyone who is responsible for rigging must understand the legislation before proceeding with any rigging work. Rigging is one of the most dangerous tasks in the theatre and it presents hazards for:
• The operator (musculoskeletal and other bodily injuries)
• The performers or crew onstage below (being crushed by falling scenery)
• The audience (being crushed by falling scenery)
• Other set pieces, furniture, stage floors and the rigging equipment itself.
