On what? Someone qualified to do so should decide just what area needs to be classified and put that on a set of drawings, or document it in some other way.Pushpin said:

Someone qualified to make the judgement should make it. Railroad sidings are not exactly something a lot of people have that much familiarity with. The only ones I have ever dealt with were in a chemical plant where everything in the area of the rails was classifed (mostly div 2), even stuff well above grade.

Gentlemen, if you do not want to be helpful then don't bother posting.
Pushpin, someone will likely chime in with a helpful answer give it some time.

One of the reasons I didn't chime in earlier is Bob's (petersonra) responses are basically correct although they could have been a bit more charitable.iwire said:
I guess I should simply add this: there is insufficient information in the OP to answer the question. No distances other than the elevation were mentioned. The method of material transfer also affects the answer.
In addition, the NEC just doesn’t answer the question at all. The proper Standard(s) is (are) NFPA 30, NFPA 497 or possibly, API RP500
A qualified person, knowledgeable of the whole installation should document the electrical area classification – then the OP can be answered.

I apologize for being insufficiently charitable.rbalex said:
I did not mean to sound harsh, but sometimes what one writes sounds harsher than what one meant.
Bob Alexander is much better at writing in a way that is less likely to be taken unfavorably than I am.

I'm not sure, but local building and zoning codes may come into effect as well. I hope you have a good architect or engineer that is familiar with the project to work this out with.rbalex said:

Some railroads also have requirements that can be a little unusual. I know that a place I used to work had a RR track come into the building and there was a requirement from the RR that nothing could be located within 8 or maybe it was 10 feet of the tracks.DanZ said:

I am shamefaced.
I am shamefaced.
I gave some misinformation when I said the NEC doesn?t address the OP directly. The fact is, this installation falls within the Scope of Article 515 and Table 515.3 applies. A knowledgeable individual should still create the documentation.

I was a bit vage.
The Rails are 27' center to center. Because ethanol mixes easily with water...and the water table is 3' down the entire site has a water proof liner making it a swimming pool of ethanol if there was a leak.
To me the entire area should be classified and the kiosk lights, plugs, ac, and relay panel should be div 2 rated. The customer argues saying the kiosk will not be located close enough to the actual connections to the rail cars and will be elevated.
I my opion is that it has disaster written all over it.
But you know about opinions...
Like arm pits everyone has 2..... and most stink. :smile:
Ask 2 engineers 1 question and you will get 3 answers. (sorry just had to add that) LOL
