Abstract

When transporting and storing liquid fuels, explosive atmospheres can form which, under certain conditions, can be initiated with different sources, of which static electricity has proven to be the source of ignition in many cases of fires and explosions that have occurred.

As a result of the environmental regulatory requirements to reduce the noxes emitted by diesel engines, the oil industry introduced into production fuels with ultra-low sulfur content (ULSD Ultra Low Sulfur Diesel), clean burning diesel, and low sulfur content (LSD Low Sulfur Diesel). The new types of fuels present a greater risk of explosion than fuels with a high sulfur content because they have other explosive characteristics and are electrostatically charged much more easily.

The paper presents some aspects regarding the risk of explosions during the transport and storage of liquid fuels with the highlighting of additional risks in the case of ULSD

Also, the paper highlights the factors that must be taken into account when establishing the technical and organizational measures that must be taken to prevent ignition and that must be implemented in the work procedures of manufacturers, suppliers, transporters and users of ULSD.
