We have developed a web-based hydrogen safety class and are developing a hands-on hydrogen safety class. The 4-h web-based class is directed to laboratory researchers who need basic hydrogen safety information (free online access at http://www.h2labsafety.org/), and it addresses 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 schematic and component description.
