Road Tanker Filling & Emptying
|
Road tankers are capable of storing large amounts of electrostatic charges that result from the transfer of large volumes of charged liquids and powders. Unearthed road tankers can discharge incendive static sparks above 1000mJ of energy into potentially flammable and combustible atmospheres if the container body is not correctly earthed.

Mobile earthing for vehicles
|
Vacuum tankers and road tankers often have to transfer combustible material without the presence of an installed static earth monitoring system. The Earth-Rite MGV is a tanker mounted system that can verify that objects it is connected to (e.g. earth rods, pipes running into ground) will function as a reliable static earth for the tanker. |
Railcar Filling & Emptying
|
Large conductive bodies like railcar tanks are capable of storing large amounts of electrostatic charges if the tank is not correctly earthed. Vibration pads, bearings and anti-friction greasing isolate container bodies from the rail tracks impeding their capacity to dissipate hazardous electrostatic charges.

|
Mixing & Blending
|
The mixing or blending of 2 phase solids and liquids generate hazardous levels of electrostatic charges on vessels and material being processed. Vessels operating in potentially flammable and combustible atmospheres should be fully earthed to ensure electrostatic charges are not permitted to accumulate on the vessel. For large volumes it is advisable to interlock the earthing equipment with the motor or other safety measures like emergency sounders.

Filling IBCs and Large Containers
|
Filling IBCs and large containers with flammable liquids has the potential to generate a serious fire hazard if the IBC is not correctly earthed. Wherever possible output contacts should be used to stop filling should the IBC lose its earth connection thereby preventing the rapid accumulation of static charges on the IBC.

Filling & Emptying FIBCs
|
Powder conveying and filling generates high levels of electrostatic charge on FIBC bags. It is essential that Type C FIBC bags regularly used in potentially combustible or flammable atmospheres are capable of dissipating electrostatic charges to ensure the powder or FIBC bag is not capable of releasing high energy static sparks or propagating brush discharges into the local atmosphere.

Filling & Dispensing Small Drums & Cans
|
For low volume liquid transfers it is important to fully bond or earth small drums and cans to ensure any charge generated is quickly dissipated as static sparks can readily ignite the liquid being handled.
