I'm not sure I'm posting in the correct forum. Anyway:
NEC and fire code require that E-stop for gasoline dispensers be more than 20-feet,
but less than 100-feet away.
I have a gas station going up now and the building is more than 100-feet away. So they need to basically put an emergency stop in the parking lot somewhere (protected, bollards, etc.). My question has to do with the reasoning behind the required distances. They want to basically take the center dispenser island, extend it out like a peninsula, and place the E-stop there. There are two additional dispenser islands on either side of the center dispenser island. The emergency stop is relatively close to the dispensers, but just over 20-feet. It's between 20 and 100 for all the dispensers. So I can't find anything wrong with this design. I'm curious:
- Where does the distance requirement come from?
- What is the basis for these distances?
- Does anyone see a possible hazard from the design that I describe above?
