On 1st June 2015, due to the reclassification of the vaporisation temperatures (flash points) at which certain liquids become “hazardous”, Diesel, along with heating oil, was re-classed as a flammable liquid. This means that equipment used in the dispensing, transfer and storage of diesel, along with other fuels, must now be subject to consideration with regard to the ATEX Directive (2014/34/EU).
ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres:
Ignition of diesel can only occur when it is heated to a high enough temperature for it to vaporise as it is only diesel vapour which can ignite, not the liquid itself. This temperature was previously considered to be 55° Celsius or under which placed diesel outside the flash point range for flammable liquids.
This flashpoint range has now been increased to 60° Celsius and this, combined with newer grades of diesel now having flash points as low as 52° Celsius, re-classifies diesel as a flammable liquid, although not in the same category as petrol.
If it is possible for the ignition of diesel to occur during the normal operation of a product then the ATEX directive must be applied and the product must be certified accordingly.
If it can be proven that diesel ignition will not occur during the normal use of a product then the ATEX directive need not be applied to it.
