Fire zone classification of Jet fuel storage area

[krishnarajsn]

Dear All,

What would be the fire zone of an aviation fuel (Jet A1) storage and handling area. It consists of 4 storage tanks, tanker loading area, tank loading facilities, etc.

Thanks
Kris

Does the fuel have a closed cup flash point temperature > 37.8 degrees C and is it stored at NTP? If so, hazardous location electrical classification is not required by NFPA 70, National Electrical Code.

NFPA-30 is a complex and lengthy document that covers tank and component location, emergency venting and many other provisions. Suggest that you contract with a consultant about tank farm/handling facility layout and component selection

According to this typical MSDS for Jet fuel A-1, the flash point is >100F and the OSHA/NFPA classification is Combustable class 2

There can be considerable variation in properties for A-1

This thread would be better suited in the eng-tips "Storage Tank" forum
