IOSH's Hazardous Industries Group commissioned the event alongside the Health and Safety Laboratory (HSL) to explain the rationale behind the strict systems governing the sector.Making use of HSL’s extensive large-scale testing facilities, demonstrations included a dust cloud explosion, drum bursting, pool fires and hydraulic fluid fires. The event, called ‘Hazardous industries with a bang – an introduction to process hazards’, was hosted by HSL, which is part of the Health and Safety Executive, on Wednesday 9 November.
