Does anyone know the standard for installing an emergency shut off at fuel pumps. I'm not talking about a gas station. This is at my work (stone quarry- per MSHA regulations). I need to install one at our fuel pumps to meet our safety department requirements. I have never installed any hazarous location equipment, so I'm not up on the standards.
Also any information on how this is typically done in a simple way. We have two pumps that need to simultaneously shut down on contact.
Thanks for any information.
