We are developing two hydrogen safety classes each respectively directed to laboratory researchers and technical operators. Laboratory researchers who need basic hydrogen safety information may now benefit from a 4-hour web-based hydrogen safety class (free online access at http://www.h2labsafety.org/) addressing hydrogen fundamentals: properties, pressure and cryogenic safety, emergency response and codes and standards. Technical operators in charge of building and testing experimental hydrogen equipment will also soon benefit from a more comprehensive 3-day hands-on safety class that will present detailed information for installation, testing and operation of hydrogen pressurized systems. The hands-on class includes a full day of classroom instruction followed by two days of laboratory work where students assemble, test and operate a pressure system based on a system schematic and component description. We strongly encourage participation of the hydrogen community to improve the technical and educational aspects of the classes by providing feedback and comments.
