AEM on ULSD ignition hazard

The Association of Equipment Manufacturers (AEM) has released guidelines on the use of ultra low sulphur diesel (ULSD).

In the guidelines, ULSD... Not Your Same Old Diesel Fuel Anymore, the AEM states that there is a greater risk of static electricity ignition hazards associated with use of ULSD. This risk is believed to be caused by the removal of sulphur and other compounds in ULSD fuel. As a result, the AEM said that, “Static electricity discharge when combustible vapours are present could result in a fire or explosion.”

“About 90% of off road equipment is run on diesel and at one time the fuel had upwards of 5,000 ppm sulphur content compared with 15 ppm today,” explained Mike Weber, AEM technical and safety services manager. “ULSD is now required for on highway and off highway applications in the North American market and we need to educate users who may be unaware of the changes in the physical properties of ULSD and the potential for harm during refuelling.”
