Motor Fuel Dispensing Facilities

[lizzie14]

I was trying to understand the hazardous classifications of a gas station. If you've got one pump, do you got 20' out from any corner of the dispenser? How far up from the dispenser is class 1 div 2? I'm looking in NEC 514 but need help interpreting. I'm trying to install light fixtures but need to know what type to install.

Extending 18" horizontally from the four sides of the dispenser,extending up to level vertically, of the dispenser height.*See figure 514.3 page 70-394 of '05

*Luminaires,wet/damp location..~410.4(a)

Edited: haven't seen canopy in the newer installations of the super-pumpers,that are designed in a way of the trapping of vapors.Generally of the -flat- design..
