How Dangerous is Hydrofluoric Acid?
Hydroflouric acid poses a significant risk to the health and safety of your employees and can be fatal even in small amounts. This highly toxic chemical penetrates quickly and deeply into tissues, causing substantial damage. Due to its ability to breach skin and other tissue barriers, hydrofluoric acid reaches deep structures like muscles and bones, reacting with vital ions such as calcium and magnesium. This creates a dangerous imbalance that disrupts cellular functions and leads to necrosis. Its rapid and deep penetration makes hydrofluoric acid more dangerous than many other acids, which typically cause only surface damage.
Skin and Mucous Membrane Burns
Contact with hydrofluoric acid on the skin results in severe burns characterized by deep, painful wounds, with pain often delayed. This delay can lead to an underestimation of the severity of the injury and a lack of necessary immediate actions.
Respiratory Damage
Inhaling hydrofluoric acid fumes causes severe irritation and burns to the respiratory tract. High concentrations or prolonged exposure can lead to chronic damage and pulmonary edema, which can be fatal in severe cases.
Poisoning Symptoms
Systemic symptoms of hydrofluoric acid poisoning include nausea, vomiting, and diarrhea, which can lead to severe electrolyte imbalances. These imbalances affect the cardiovascular system and can cause arrhythmias, requiring urgent medical intervention.
Legal Regulations for Handling Hydrofluoric Acid

Regulation on Facilities for Handling Water-Hazardous Substances
In Canada, the handling of substances that pose a risk to water resources is governed by regulations under the Canadian Environmental Protection Act (CEPA) and various provincial environmental protection laws. These regulations outline the requirements for the storage, handling, and transportation of water-hazardous substances, including hydrofluoric acid, to prevent environmental contamination and ensure the protection of water resources.
First Aid Measures for Hydrofluoric Acid Accidents
As soon as a hydrofluoric acid accident is identified, immediate action must be taken, and the company’s emergency management procedures must be followed. The top priority is the safety of the responders and the immediate alerting of emergency services. Those providing first aid must ensure their own safety and wear appropriate protective equipment.
Important: In all cases of hydrofluoric acid exposure, quick action is essential. In addition to the described first aid measures, always seek professional medical help. The full effects of exposure can be delayed and often severe.
In Case of Eye Contact
Rinse Eyes: The eyes must be immediately and thoroughly rinsed with water. This rinsing should start at an eye wash station at the workplace and continue on the way to the hospital.
Call Emergency Services: The eye must be examined immediately, as hydrofluoric acid injuries to the eyes are always considered life-threatening. The sooner the eye is rinsed, the better the chances of preserving vision.
In Case of Skin Contact
Immediate Washing: The affected area must be thoroughly rinsed with flowing water immediately. This should continue for at least 15 minutes to dilute and remove the acid from the skin as effectively as possible.
Application of Calcium Gluconate Gel: After rinsing, apply calcium gluconate gel to the affected area or inject it into the affected tissue as a solution. This gel helps neutralize the hydrofluoric acid and prevent further tissue damage. Ideally, treatment should be supervised by medical personnel.
In Case of Inhalation
Fresh Air: Immediately move the affected person to fresh air. Avoid having them take deep breaths if it aggravates their symptoms.
Medical Emergency Care: Continuously monitor the person and immediately call emergency services. Pay special attention to signs of breathing difficulties or chest pain, as these may indicate severe damage to the respiratory tract.
In Case of Ingestion
Do Not Induce Vomiting: Do not induce vomiting, as this could further damage the esophagus and mouth.
Immediate Medical Attention: Seek medical help immediately or call emergency services. Provide the medical personnel with detailed information about the exposure to hydrofluoric acid.
Prevention and Protection Measures
To prevent the need for first aid following a hydrofluoric acid burn, it is crucial to implement prevention strategies and appropriate protective measures when handling this hazardous substance. Here’s an overview:
Risk Assessment and Substitution Check: Before using hydrofluoric acid, a comprehensive risk assessment must be conducted. This analysis helps identify and evaluate potential risks. Additionally, it should be assessed whether hydrofluoric acid can be substituted with less hazardous substances according to the STOP principle.
