Hazardous area classification of diesel engine driven generator
Hazardous area classification of diesel engine driven generator
(OP)
Dear all
Can anyone tell whether it is compulsory to consider DG Set as a sourse of hazard and hence select a DG suitable for Hazardous area . I am aware that in some countries, due to low flash point of Diesel , this clssification is done and hence DG becomes sourse of Hazard.
Additionally who are the manufactures of this kind of DG set .
Thanks

Our specifications required an explosion-proof level switch inside the fuel storage tank. Every bidder took exception to this, saying that this was not required by Code, due to low flammability of diesel fuel, and they were right.
This may have changed, but at the time, I don't believe there was any requirement to classify anything as a hazardous location.

To address this, NFPA typically allows a maximum indoor fuel storage volume of 550 gallons. Beyond that, the fuel needs to be divided into separate fuel storage vaults (typically with a 3-hr concrete separation?).
The local AHJ will most always have his own interpretation, though. This is true in both small rural towns and large cities.

If you have a significant volume of fuel, a common practice is to have a separate fuel tank room, classified as hazardous, or to have the tank outdoors. However the DG room should not be hazardous.
