Hydrochloric Acid Hazard and How to Stay Safe

Learn about Hydrochloric Acid safety

What Is Hydrochloric Acid?

Hydrochloric acid, also known as muriatic acid or HC1, is a chemical compound composed of hydrogen and chloride. It is a highly corrosive, pungent liquid that can cause serious burns, tissue damage, and cause chemical burns when it comes into contact with the skin. For these reasons, it is important to understand not only the HCL hazards exposure but also how to stay safe when using this substance.

What does Hydrochloric Acid smell like?

Hydrogen chloride is an odorless, colorless, corrosive, nonflammable gas. Many of us might wonder as well as question, what does hydrochloric acid smell like? Using a standardized procedure, a trained odor panel, and high-purity hydrogen chloride, Leonardos et al. (1969) assessed the odor threshold of hydrogen chloride to be 10 ppm; the panel described the odor as "pungent."


Hydrochloric acid is most commonly found in:

  • Pickling with steel
  • Making organic compounds (for activated carbon, PVC, ascorbic acid, as well as pharmaceuticals)
  • Manufacturing water treatment chemicals
  • pH control of water
  • Leather preparation
  • Purification of salt
  • Cleaning products for the home
  • Oil well acidification in building construction
  • Making gelatin products

HCL Hazards

One of the main dangers of hydrochloric acid is its corrosive properties. This acid can cause chemical burns to the skin and eyes if it comes into contact with them. It can also cause damage to the respiratory system if inhaled, leading to symptoms such as coughing, wheezing, and shortness of breath. Additionally, hydrochloric acid can irritate the nose and throat, causing discomfort and potential respiratory damage.

One of the greatest hydrochloric acid hazards is its corrosive and destructive properties. Inhaling hydrochloric acid vapors, such as when it is used in industrial processes, can cause respiratory irritation and even lung injury. Direct contact with the skin, eyes and mucous membranes can also cause severe chemical burns, scarring, and even blindness. Ingesting hydrochloric acid can lead to chemical burns in the throat and esophagus, damage to the digestive tract and other organs, and even death.


To stay safe when using hydrochloric acid, the first recommended step is to always use it in well-ventilated areas and wear appropriate protective equipment. This includes gloves, chemical-resistant face shields, protective clothing, and protective boots or shoes. It is also important to never mix hydrochloric acid with other chemicals, as this could cause hazardous chemical reactions.

In addition to wearing appropriate protective equipment, it is also essential to follow recommended safety protocols. This includes avoiding contact with the acid and using only approved storage and disposal containers for the acid. It should also be kept away from sources of heat, open flames, or sparks to prevent accidental fires. If a spill occurs, it is important to stop any spills immediately, wear protective equipment and neutralize the acid with baking soda or other approved substances.

When handling hydrochloric acid, it is important to follow all local, state, and federal regulations, as well as the manufacturer’s instructions. This includes information on safe handling, storage, and disposal procedures. It is also important to keep a first-aid kit and an emergency plan in place in case of an accident. In the event of a spill or exposure, it is important to take immediate action to minimize the risk of harm. If the chemical comes into contact with the skin, rinse the affected area with water for at least 20 minutes. If it gets into the eyes, rinse them with water for at least 15 minutes and seek medical attention immediately. If inhaled, move to an area with fresh air and seek medical attention if symptoms persist.
