A massive explosion at a sugar refinery in Fort Wentworth, US is a reminder of the devastating force that can be generated by a dust explosion.
The explosion that occurred on 7 February 2008 has claimed 12 lives so far, with 11 people remaining in a critical condition in hospital. The source of ignition is being investigated, however the fuel was fine airborne sugar dust in the load out area under the concrete storage silos.
Beware that a gas monitor fitted with a flammable gas sensor will not warn of a potential dust explosion. The risk of a dust explosion increases depending on the amount of airborne dust, the size of the dust particles, the amount of air humidity (lower humidity is higher risk) and the type of dust.Source: www.nbcaugusta.com
