For ensuring fire safety distributing fuel pumps and connecting fuel hoses have to be reliably grounded. This requirement is especially urgent for mobile gas stations.

On the distributing pumps and fuel hoses which are especially made of plastic considerable charges of static electricity can accumulate. It is promoted by certain atmospheric conditions, and also friction of fuel in a flowing part of the distributing pump and in hoses.

Pumps, hoses and land fuel capacities of mobile gas stations have to be surely grounded.
