The Trojan Horse Messaging Project is a very grand name for a very simple idea: putting pictorial safety stickers on bits of equipment and building components. But it works.

A year-long study of 70 workers across 11 building sites around the UK, organised by Loughborough University, showed that workers got the message and altered their behaviour after the stickers appeared. The other advantage is that you don’t need to speak English to understand them.

The next phase of the research, which is being led by Dr Viken Chinien of the Steel Construction Institute, is to develop a set of pictorial messages with input from trade associations and manufacturers. These will be available to everyone on a website.
