SAFETY IN THE PLANT


AVOIDING EXPLOSIONS


A short guide to dust safety characteristics and explosion prevention

T


he topic of ‘explosion safety’ is widespread for plant operators and OEMs when it comes to handling or transporting


combustible dusts. Despite the common assumption that an increased risk of explosion only exists for gases, enormous forces can also be released by explosive dust air mixtures.


To help minimise the risk of explosions when handing combustible dusts, it is important to understand the requirements for an explosion and the respective dust safety characteristics. Figure 1 uses the explosion pentagon to outline the elements that should be considered by safety engineers. Every condition within the explosion


pentagram must exist for an explosion to occur within a production facility or machine.
