Chemical reaction hazards and the risk of thermal runaway

You must assess the risks of your chemical processes but this does not need to be time-consuming or expensive You should then ensure that the systems in place reduce the risk of runaway to a level that is as low as reasonably practicable The effort you take to do this should reflect the complexity of the process and the scale of risks involved...
