Kerosene is not generally considered to create a classified location.

Looked in 2005 NEC Handbook Page 658 (KEROSENE) is there.Flash Point 72% C. looks like Class 2 (A)or Class 1 Division Group D. ?? listed two places. Check it our .
Theres an Area with Diesel Fuel, & Kerosene.
Diesel Fuel I think NO.

K-1 maybe, kerosene is a generic term, it would depend on the product. The oil company should be able to tell you flash point

Based on a quick read, I'm leaning to "same as diesel". If I had to make an official 'call'; I would do some additional research.

Careful here ... home oil heating units do not require any "haz loc" wiring - and kerosene / fuel oil / diesel / jet fuel are all essentially the same thing. Nor should we forget the sundry decorative oil-filled 'candles' that are actually filled with scented kerosene.

Yoopersup,
What sort of an installation is this referring to?

I know for a fact that choppers I have flown run on a variant of Kerosene and it has a flash point of about 250C.

One other thing I do know, through experience as a FF, is that kerosene has the habit to change from a liquid to vapour very easily, about the same as propane, but not with the explosive force.

Unlike propane, the fumes from kerosene will drift upwards.

Yoop:
Yes, I read the Handbook info & agree with you on that. There's a lot of info that has to be read regarding that table, which I have not read due to time constraints. I have not had a job with kero dispensers, so I have no 'field' quick answer for ya.

Perhaps reach out a PM to 'Walrus'...he's a service station guy.
