The dangers of Hydrochloric AcidHydrochloric acid is rated and regulated as a toxic substance.

Concentrated hydrochloric acid, known as fuming hydrochloric acid, will form acidic mist. This mist and the solution both have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines irreversibly.

Dangers of hydrochloric acid through exposure

Exposure via oral consumption can cause corrosion of the mucous membranes, esophagus, and stomach, with nausea, vomiting, and diarrhoea. Contact to skin produces severe burns, ulceration, and scarring.

Exposure through inhalation can cause coughing, hoarseness, inflammation and ulceration of the respiratory tract, chest pain, and pulmonary edema (fluid accumulation in the lungs).

A toxic chlorine gas can also be produced when mixing hydrochloric acid with common oxidising chemicals, such as bleach (sodium hypochlorite).

Be aware of the dangers of hydrochloric acid when handling. It is important to wear personal protective equipment such as acid-proof gloves, protective eye goggles, chemical-resistant clothing and shoes so as to minimise risk of harm.

Safety when acid etching metal surfacesOne of the most difficult parts of the process when acid etching metal surfaces is safety. When working with acid in any form, always add the acid to water and NOT water to acid. Adding water to acid can cause a chemical reaction, which may produce a very rapid heat. This can, on occasion, cause an explosion of the solution.

Rules for acid etching metal surfaces

  • Make sure you work in a well ventilated area.
  • Wear rubber gloves to protect hands.
  • Mix the acid at least an hour before you start your etching, as Acid and water are slow to mix.
  • Never poor the acid solution down the drain

Hydrochloric Acid Safety Instructions: Avoid contact with skin or eyes, avoid breathing vapours, wear suitable protective clothing, gloves and eye / face protection when using this product.
First Aid:
For advice contact Poisons Information Centre on 131126 or a doctor. If swallowed, do NOT induce vomiting. If in eyes, hold eyelids apart and flush the eye continuously with running water. Continue flushing eye until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes. If skin or hair contact occurs, remove contaminated clothing and flush skin and hair with running water. Additional information is listed on the Material Safety Data Sheet.

NOTE: Never mix Hydrochloric Acid with Sodium Hypochlorite (Chlorine). Always add acid to water (NEVER ADD WATER TO ACID).
