Chemical Earthing is a traditional earthing system whereby chemicals are added to earthing pits such as bentonite or graphite-based compounds used that helps in improving the condition of the soil and reducing the soil resistivity. Chemicals are used in this earthing type to lower earthing resistance.

Earthing plays a crucial role in preventing accidents in petrochemical facilities. By providing a safe path for electrical current to flow, earthing helps to prevent electric shocks and equipment damage caused by lightning strikes and power surges.
