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.
