Replacing light fixture above motor fuel dispensing station

[matt_mackay]

I have to replace a light fixture located approx. 15' above a gas pump. The light fixture I am replacing is an explosion proof fixture. The conduit feeding the fixtures exits the ground between 2 fuel pumps, rises approx 15', tees and feeds 2 explosion proof light fixtures above the pumps. The vents for the pumps are at the same height as the light fixtures. The fuel tank is underground. My question: because the conduit feeding the fixtures is located in a class I Div I and the vents are within 5' of of the fixtures are the light fixtures required to be explosion proof. I'm thinking yes because of the vent location.
Thanks for any input

The area arount the vent opening is a hazardous location.

Table 514.3(B)(1) is where you need to look.

3 feet from vent opening is CL1D1, 5 feet is CL1D2.

If you are beyond 5 feet it is unclassified.

If unclassified make sure raceway is sealed if it passes through classified area to get to your light location.
