Filling or handling plastic or other non-conducting containers can still be hazardous when the flammable liquid is conductive. The splashing (filling) and turbulence of the liquid in the container can cause a static electric charge to build up in the liquid or on conductive parts of the container that are not adequately grounded. A spark above the MIE of the vapor/air mixture in its flammable range (an incendive discharge) can originate from the liquid or the container.
