Why the spillage has a cost? Ø  Safety: spillage can cause an accident

and generate operation lost (asset and lost time)

Ø  Can damage tires (tire price USD US$ 40000 each if it needs to be replaced).

Ø  Support equipment is needed to clean the loading area as well as roads.

Ø  Inefficiency at production . Lost of material before to arrive to the crusher. Lower speed to avoid road spillages.
