Abstract: A fueling station dispenser for distributing a combustible gas that is lighter than air, and that includes electrical and gas handling sections in the same frame. A vapor barrier in the cabinet blocks fugitive gas that may be present in the gas handling section from entering the electrical section. According to most applicable codes, by isolating combustible gas from the electrical section gives it a Class I, Division 2 designation. Which eliminates the need to seal or air purge the electronics section as this designation allows for electronics that under normal intended operating conditions do not generate an arc with sufficient energy to initiate combustion.
