Dust - a Safety Risk
Why dust is an explosive subject
A dust explosion needs three things: Air, combustible dust, a source of ignition!
The following three conditions must be satisfied for a dust explosion:
| »
| A cloud of combustible substances with a particle size smaller than 0.5 mm. The concentration of this dust cloud must be between the lower explosion limit (LEL) and the upper explosion limit (UEL). The LEL for many food dusts, for example is between 30 and 60 g/m3, the UEL is 2 to 6 kg/m3.
|
| »
| A sufficient amount of air oxygen.
|
| »
| A suitable ignition source, e.g. an electrical spark which may occur when pulling a plug out of a socket or a hot surface (e.g. 300°C to 600 °C).
