White model to final design


  • To continue identifying potential hazards within the set design, to eliminate them through design where reasonably practicable, and to continue to update your risk assessment documents accordingly.
  • To establish if and what new machinery you will be manufacturing as part of the set build.
  • To establish if you are building an assembly of machines and if so, which sections of machinery will be built as new or modified from existing.
  • To establish if the machinery will be manufactured in-house or by an external contractor.
  • To consider what legislation applies to your machinery. For example, in the EU and UK, machinery that is intended to move items or persons other than performers must comply with the Machinery Directive 2006/42/EC and The Supply of Machinery (Safety) Regulations, 2008.
  • To consider what British Standards, European Standards and / or International Standards apply to the design, manufacture, commissioning and maintenance of machinery. A competent engineering specialist can assist you in determining which standards you will need to apply.
  • To begin drafting your Engineering Design Specification to include the performance scope and restrictions of the machinery, and its functional characteristics.
  • To start the process of putting together a Technical File for each machine. You can use the Technical File Contents List Template as a guide as to what should be included in the file.


Machinery: “An assembly, fitted with, or intended to be fitted with, a drive system other than directly applied human effort, consisting of linked components, at least one of which moves, and are joined together for a specific application” (taken from the ‘Supply of Machinery (Safety)’ Regulations, 2008). A load that is put into or onto a machine for positioning or transportation is not part of the machine. For example, a piece of scenery that is placed onto a revolve for re-positioning as part of a scene change is not part of the revolve machinery.

Technical File: A file consisting of documents that includes information about the design, manufacture and operation of a machine or assembly of machines. In some countries this file is required by law for machinery that is intended to move items or persons other than performers.

Competent Engineering Advisor: Someone with suitable skills, training, knowledge and experience. You should look for engineers who hold recognised engineering qualifications and accreditation, for example, a chartership held with a national or international engineering body.


Have you…

  • confirmed what machinery you are going to be manufacturing
  • confirmed if the machinery is made up of an assembly of other smaller machinery
  • determined what regulations, international and national standards apply to your machinery and obtained competent engineering advice as required
  • decided who will be manufacturing your machinery
  • completed your Engineering Design Specification
  • eliminated by design as many hazards as possible
  • where not possible to eliminate hazards through design, have you provided technical protection against these hazards
  • where not possible to eliminate hazards through the provision of technical protection, have you provided clear information and instruction about the control of these hazards
  • have you made provision to give clear safety instructions and information to those who are manufacturing the machinery
  • written an engineering design specification for the machinery
  • started to put together a technical file for each machine?
