EPA Chemical Emergency Preparedness and Prevention Advisory Hydrogen Fluoride
United States. Environmental Protection Agency
"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."

Citing HSDL Resources

Documents from the HSDL collection cannot automatically be added to citation managers (e.g. Refworks, Endnotes, etc). This HSDL abstract page contains some of the pieces you may need when citing a resource, such as the author, publisher and date information. We highly recommend you always refer to the resource itself as the most accurate source of information when citing. Here are some sources that can help with formatting citations (particularly for government documents).
