With consideration of the conditions that exist with respect to the location of the Reli-On HSM16 fuel cabinet containing 16-510 SCF hydrogen cylinders, totaling 8160 SCF, is installed within the Class I, Division 2 location of the electrical equipment, the proposal to install and 2 hour rated constructed CMU wall between the HSM16 Fuel Cabinet and the electrical equipment, this request is being APPROVED without the installation of the CMU wall. It is of our opinion that the properties of hydrogen allow for rapid dispersion and would not be a hazard in this type of installation. Evaluated by JPD Reviewed by: , Joseph.
