ABSTRACT

Hydrogen Fluoride Study: Report to Congress Section 112(n)(6) Clean Air Act As Amended   [open pdf - 4MB]

"The purpose of this report to Congress is to study the hazards associated with the production and uses of hydrofluoric acid and to make recommendations about reducing these hazards based on the findings, In this report anhydrous hydrogen fluoride will be designated as HF; aqueous solutions of hydrogen fluoride will be called aqueous HF. This distinction is important especially when considering such things as severity of exposure, corrosivity, and likelihood of fuming and forming dense vapor clouds upon release. Although worker exposure and environmental impacts from routine emissions are important issues, this report focuses primarily on the potential hazards to the public from accidental releases of HF during production, use, transport, transfer, and storage. Analysis of public exposure to routine emissions was not included in this study because the statutory language focuses on worst-case releases from accidents. EPA was directed by Congress to carry out a study of hydrofluoric acid, a toxic, corrosive material, which when released under certain conditions, can form a dense vapor cloud, travel downwind, and pose a serious threat to the public. This report, developed in response to the Congressional mandate, identifies and evaluates hazards to the public posed by the production and use of HF."
