Milling and grinding operations, dust collection, container filling and general movement of combustible powders and solvents are significant sources of static electricity. After mechanical spark ignitions, uncontrolled discharges of static electricity are the highest reported source of ignition in combustible dust cloud explosions.
Static electricity can lead to large voltages on tank trucks.

The Earth-Rite Multipoint monitoring system is an ideal way to ensure that our equipment is grounded and bonded prior to processing potentially combustible powders. The ATEX certification enables us to use the Earth-Rite Multipoint system is Ex-zoned hazardous areas.
The "Earthing & Bonding Applications - Controlling Static Electricity in Hazardous Areas" document by Newson Gale is a very good, easy to read document. It provides practical advice and has great illustrations. It contains a lot of good background information and references various regulations throughout. The fact it includes comparisons between European (Cenelec), American (NEC) and International (IEC) Hazardous Area Classification and is available in many languages makes it an excellent reference document.
