Pressure Safety Data Package for Remote Balloon Launcher (RBL)
The Barrow Hydrogen Fill System is intended for use by the authorized Sandia National Laboratories personnel and its contractors who are involved in research relating to the deployment of weather balloons for the Department of Energy's Atmospheric Radiation Measurement Program (ARM) https://www.arm.gov/ and The National Weather Service (NWS) https://www.weather.gov/. Hydrogen is supplied from a hydrogen generation shelter and outdoor storage tank. The balloons are filled and released by a remote balloon launcher (RBL) commercially available from Vaisala. The RBL was designed to be used with helium or hydrogen and has be recently inspected by Vaisala for hydrogen operation. This system is composed of a pressure regulator, ball valves, pressure relief valves, tubing, hose. All pressurized components are "off the shelf items and have a minimum pressure rating of 300 psi and are assembled using "Best Practices" and trained pressure component installers. Non pressurized components are comprised of industry recommended components and are assembled using "Best Practices" techniques.
