Shut Off Systems for Hazardous Gases Such as Hydrogen Cyanide (HCN)

About Hydrogen Cyanide

Hydrogen Cyanide is a colorless gas or bluish-white liquid with a bitter almond odor. It is also known as prussic acid. Hydrogen Cyanide is very toxic and, in air, forms a severe fire hazard. Hydrogen cyanide is absorbed well by inhalation and can produce death within minutes. Substantial absorption can occur through intact skin if vapor concentration is high or with direct contact with solutions, especially at high ambient temperatures and relative humidity.

The principle use of hydrogen cyanide is in the manufacture of organic chemicals, e.g., acrylonitrile, methyl methacrylate, and adiponitrile, that are used in producing synthetic fibers and plastics. It is also used in the chemical laboratory, and is sometimes used in agriculture as a fumigant. Hydrogen cyanide is shipped in pressurized containers and tank cars.

Prevent Accidental Release of Hydrogen Cyanide

Powell's Emergency Gas Shut Off Valve Closure Systems are designed to prevent significant releases of hazardous gases like hydrogen cyanide. In the case of an accidental release, the emergency valve closure system will close the valves in 10 seconds or less, effectively preventing further release from the container.
