Hydrofluoric Acid: What You Need to Know

An excellent article by paramedic Bradley Denney who suffered HF burns from a refinery accident. It gives much information about HF – its properties, dangers, treatment and its transport – in great detail.

Bradley Denney, RN/MICT, has been involved with the fire service for over 38 years and EMS for over 36 years. He has worked as a frontline firefighter and EMT to assistant fire chief and hazardous materials technician and paramedic. In 2007, he became a registered nurse. He has taught hazmat courses for fire, law enforcement and EMS, and taught HF-specific classes at the Kansas HazMat/WMD Symposium in 2006 and 2007. He also has over 15 years of experience working with HF acid in the oil refining industry. He was instrumental in initiating first aid protocols in the refinery emergency facility setting that ultimately would save his life.

Read the entire article from EMSWORLD here. The following, taken from the article, is part of his story:

I became interested in HF while working in an oil refinery that uses it as a catalyst to make high-octane gasoline. As a paramedic, I found the effects of HF on the human body fascinating. I learned what I could about it and began teaching HF safety to my coworkers.

Then, in 2001, I was involved in an HF incident in which I was seriously exposed. I had been sprayed with anhydrous HF at approximately 150 pounds of pressure when a ¾” pipe broke at an ell as I was preparing to remove a plug. The HF had eaten the threads inside the ell and the weight of my pipe wrench caused the damaged pipe to give way, spraying both my legs just below my groin, and my right forearm. That exposure began a battle for my life that continues today.

Luckily, our local EMS and emergency facility had been trained on the dangers of this acid and proper treatment. Many EMS and ER personnel have probably never heard of this dangerous compound, but all emergency services, fire or law enforcement personnel who operate near and may be called to respond to any facility that uses or manufactures a form of HF should receive yearly training on treatment for HF exposure. This information should be available from your county LEPC.

After I was burned, the HF acid penetrated the Nomex coveralls I was wearing under my coat. (The photo of my left leg shows the flame pattern caused by the splatter from acid hitting my right leg.) The fluoride immediately penetrated the skin and bound to the calcium and magnesium in my blood and body tissues, which caused severe heart arrhythmias about 1 hour post-burn.

I was flown by helicopter to a burn center at Hillcrest Hospital in Tulsa, Oklahoma. There, despite the fact that I had at least 16% BSA, the burn center doctors and cardiologist refused to let me die. They called all over the world, looking for help from HF specialists and were told, “Make him comfortable, let his family say goodbye, and let him go.” Thank God, they refused and kept working on me. They stopped counting the defibrillator shocks after 15. (By the way, THAT HURTS!!!) By the grace of God, a very dedicated nurse, and those stubborn doctors, I am still here.

US EPA adopts halfway measures that fails to protect communities from hydrofluoric acid (HF)

On March 1, the EPA released its Chemical Disaster Prevention Rules. Following that, TRAA released this Press Release:

The US Environmental Protection Agency (EPA) today announced the release of a final revision to the Risk Management Plan (RMP) rule governing 11,740 facilities using dangerous chemicals, including 40+ oil refineries that use hydrofluoric acid (HF), a deadly chemical capable of causing thousands of deaths in a few minutes. (see attached “Summary Info Sheet”) (link)

The new RMP rule includes many positive improvements and states its goal is “to protect the health and safety of all communities by requiring industry to prevent accidental releases of dangerous chemicals that could otherwise cause deaths and injuries, damage property and the environment, or require surrounding communities to evacuate or shelter-in-place”. EPA 3/1/24. For some positive developments see the statement from Environmental Justice & Health Alliance (link).

However, the Rule fails to protect vulnerable Environmental Justice burdened communities living near HF refineries in 20 states. The EPA recognized that HF units are vulnerable to accidents, natural disasters, and terrorist acts. However, the new rule does not meet the standard set by California Attorney General Rob Bonta and 20 other State AGs in their 2022 letter to the EPA which quoted the US Chemical Safety Board saying that it is “fully within the authority and responsibility of the EPA pursuant to …the [Chemical Disaster Rule] Risk Management Plan (RMP) Rule (40 CFR Part 68.67) as well as through its General Duty Clause.” … “to impose a robust safer technology protocol that will drive the remaining hydrofluoric acid-using refineries to identify and implement safer alternatives”  

(Full letter available on request, excerpts (link to AG excerpts)).

The new rule makes significant improvements over the Trump era version by restoring the requirement that HF refineries do an analysis of safer alternatives. It adds for the first time requirements to analyze the “practicality” of these alternatives, requiring HF refineries to state why they are not using safer chemicals. This provides the EPA a tool to “influence” HF refineries toward implementation of conversion. Many of the improvements over the draft rule stem from grass roots advocacy. For example, the United SteelWorkers scored victories in the significant expansion of worker participation in safety processes.

Many of the HF dangers highlighted by TRAA, as well as those alerted to by national security experts, are referenced in the EPA release. Nonetheless, TRAA sees this rule as a three-legged stool without its 3rd leg. Without requiremening conversion to a safer alternative, the rule does little to protect the community from a catastrophic, and potentially deadly, release of HF.

There are significant improvements in response to community demands but for the 14 million people living around HF refineries and the nearly 1,000,000 in Los Angeles County alone, this effort by the Biden administration to improve on the terrible record of the Trump administration is shockingly inadequate. Especially, when it is well known that President Biden and his family live within the circle of risk for the Trainer, Pennsylvania HF refinery. TRAA will not stop calling for exceptional action at the local, state or federal level to remove this exceptional danger of mass casualties.
