Monitored grounding of electrostatic charge in dust hazardous areas

What dangers are caused by static charge when handling bulk materials? Prevent electrostatic charging in accordance with best practice. Download technical article now!

Storage silos / granaries, sieves, mills or filters are typical places where hazardous dust atmospheres occur. Therefore, there are a variety of standards and best practice recommendations to ensure safety for man, machine and environment while working in these zones. The most important are TRGS 727, CLC / TR 60079-32-1:2015, TRBS 2152 and IEC TS 60079-32-1:2013.

The classification of dusts regarding their minimum ignition energy, as determined by the employer’s liability insurance association for raw materials and chemical industry (BGRCI), confirms the ignition efficiency of the calculated discharge energy. It becomes clear that electrostatic charging must be prevented in order to ensure operational safety.

Learn more about ignition sources, how to calculate the ignition energies, and why only connecting a simple grounding cable is not enough to ensure a safe grounding connection in our technical article “Dust hazardous areas | Background to the ignition risks of electrostatic charge”.
