Props, set design and special effects are used widely in theatre productions and these often rely on power from lithium-ion (Li-ion) batteries. Being subjected to constant wear and tear means repairs or alterations to these items may need to be done, in-house, by technical staff. As a result these modified items may no longer meet the same design, build, or safety standards as consumer-grade products which could increase the likelihood of failure.
Working together with the Association of British Theatre Technicians (ABTT) and the Royal Ballet and Opera (RBO), University of Sheffield researchers aim to develop industry-wide guidance for the safe development, use, and storage of Li-ion batteries in theatre environments.
The project seeks to answer worst-case scenario questions such as: "What happens when a battery inside a handheld prop short-circuits due to impact or damage?" and "What are the consequences if a wearable battery fails while being worn, either under or over a costume?"
Dr Peter Bugryniec, Research Associate at the University of Sheffield and project lead, said, “Li-ion batteries are present in many objects we use in daily life including mobile phones, battery booster packs and laptop computers. Because we use them so frequently it’s easy to forget these items can fail, unfortunately sometimes, with bad consequences. In this research project we hope to test different handheld props and compare the hazard level of three types of Li-ion batteries. We will also assess any risks associated with DIY battery assemblies.
“Ultimately our main aims are to embed safer battery practices throughout the theatre community, encourage industry-wide adoption of standardised batteries, and lay the groundwork for future collaborative research efforts focusing on larger-scale batteries in theatre.”
Tommy Cockerham, Lighting Systems Assistant Manager at Royal Ballet and Opera said, “We hope, as a result of this collaboration, we will be able to organise educational events so we can share this information with other theatres, prop manufacturers and industry professionals. By creating training materials, we hope to reduce barriers to members accessing the information.”
The project is supported by the EPSRC as part of its Impact Acceleration Accounts, a funding scheme designed to help universities develop and foster strategic partnerships for knowledge exchange and impact.
