Hydrogen Fluoride (HF) Emergency Shutoff

About Hydrogen Fluoride

Hydrogen Fluoride (HF) is a colorless and corrosive gas with a pungent odor at standard temperature and pressure. When combined with water it becomes hydrofluoric acid, a liquid. It is very toxic and attacks all tissues if inhaled or swallowed. Exposure can cause death.

Hydrogen Fluoride is the basis for all fluorides including those used in drinking water. It is also used as a catalyst in isomerization, condensation, dehydration and hydrolysis reactions. Hydrogen Fluoride is shipped in sealed tanks. Railroad tank cars carrying HF may have angle plug valves or angle ball valves.

Accidental Release of Hydrogen Fluoride

In the event of an accidental release of hydrogen fluoride, remove all sources of heat and ignition. Ventilate potentially explosive environments. If it can be done safely, shut off the hydrogen fluoride container valve using non sparking tools.

Powell Emergency Valve Closure Systems are designed to prevent significant releases of hazardous gases like hydrogen fluoride. In the case of an accidental release, the emergency valve closure system immediately closes the container valve, stopping the flow of gas regardless of where the leak occurs downstream.

It is possible to prevent an accidental release of hydrogen fluoride. Contact us today to discuss your specific application requirements.
