A resistance of 106 Ω between mobile equipment, holding tanks and vehicles of the installations is sufficient to prevent a dangerously high charge. Before each operation, e.g. the opening of tanks, the connection of pipes or hoses for filling or emptying, the mobile equipment, tanks and vehicles shall be earthed by means of a temporary protective equipotential bonding conductor so that the resistance between the equipment to be earthed and the temporary protective equipotential bonding is reduced to low, single-digit values. The temporary equalizer connection must not be removed until all operations have been completed.
