Hydrogen Chloride (HCl) Emergency Shutdown SystemAbout Hydrogen ChlorideHydrogen Chloride is a colorless to slightly yellow, non-flammable gas at standard temperature and pressure with a pungent, irritating odor. Mixed with water, it becomes hydrochloric acid (also known as Muriatic acid). Exposure to HCl can result in irritation to the eyes, throat and skin. Prolonged exposure to Hydrogen Chloride can cause death. Hydrogen Chloride is used as a cleaning gas during epitaxial deposition and as a furnace cleaning agent. It is shipped in pressurized tank cars with angle plug or angle ball valves. Synonyms: hydrocloric acid, aqueous hydrogen chloride, HCL solution, chlorohydric acid, hydrochloride, hydrogen chloride, muriatic acid, spirits of salt, UN 1050, UN 1789, UN 2186 Accidental Release of Hydrogen ChlorideIn the event of an accidental release of hydrogen chloride, remove sources of ignition and if possible without risk, shut off the gas supply. Powell Emergency Valve Closure Systems are designed to prevent significant releases of hazardous gases like Hydrogen Chloride. In the case of an accidental release, the emergency shutdown system will immediately close the container valve, stopping the source of the leak regardless of where it occurs downstream. It is possible to prevent an accidental release of Hydrogen Chloride. Contact us today to discuss your specific application requirements.
