ChE Faculty, Staff and Graduate Students, The ChE Safety Committee has developed a guideline for the use hydrogen and flammable hydrogen gas mixtures in our laboratories (https://engineering.purdue.edu/ChE/AboutUs/Safety/Hydrogen%20Use%20Guideline...). The guideline addresses hydrogen detectors, piping and tubing, shut-off valves, cylinder location and ignition sources. To ensure the safety of our personnel, all ChE labs that use hydrogen or flammable hydrogen gas mixtures should be following this guideline. Please contact any of our safety committee members with questions or for assistance: * Ahmad Al-Kukhun * Linda Davis * Vinod Kumar Venkatakrishnan * Fabio Ribeiro * Jeff Valley * Yury Zvinevich Thank you for your commitment to safety.
