Operator responsibility is a key issue in any business. Operators are required to take every reasonable action to protect their employees and the environment. Non-compliance with operator obligations can lead to severe punishments. In order to create an appropriate working environment and to implement all regulation correctly, operators have to establish clear rules and to ensure that they are complied with.

There is often a lot of catching up to do in the field of electrostatic grounding of big bags in explosion hazardous areas. Driven by underestimation of dusts‘ explosion hazards, unsupervised grounding solutions with simple clamps and cables are installed in the workplace as a protective measure. An automated monitoring of correct use and the integrity of the ground connection is not given in this application.

Conventional grounding monitoring devices continuously measure compliance with the maximum resistance of 108 Ω in the discharge connection. In the most common application, one clamp is connected to the FIBC bag and a second clamp leads to the designated grounding point of the facility via a grounding cable. Within this grounding loop, the maximum resistance is then measured and continuously monitored.

But this very type of measurement is the weak point of the system. On the one hand, the wide grounding loop makes it very susceptible to external influences. On the other hand, and much more problematic, is that these devices only check compliance with the maximum resistance. This means in practice: If the grounding clamp is connected to an object or point on the system the grounding resistance of which is within the required limits, the device will give filling release without a proper grounding connection of the big bag.

What that means for the operator and what options you have to eliminate this risk can be found in our latest white paper. Click here for the free PDF download!
