EPA Chemical Emergency Preparedness and Prevention Advisory Hydrogen Fluoride   [open pdf - 36KB]

"This advisory recommends ways Local Emergency Planning Committees (LEPCs) and chemical facilities can reduce risks posed by the presence of hydrogen fluoride (HF) in their communities. Hydrogen fluoride, a strong inorganic acid, is produced and used as a gas or liquid without water (i.e., in anhydrous form), or in a water (aqueous) solution. The anhydrous form is potentially more hazardous than hydrogen fluoride in dilute water solutions, because anhydrous hydrogen fluoride has greater potential for fuming and forming vapor clouds. If anhydrous hydrogen fluoride is accidentally released, it may react with water vapor to form a white vapor cloud. Under certain conditions, such a cloud has the potential to travel considerable distances close to the ground and pose a threat to people in its path. EPA stresses that although mishandling of HF can cause harm, there is no cause for undue alarm about its presence in the community when it is properly and safely managed."
