Hydrochloric acid (chemical formula HCl), also known as muriatic acid, is an aqueous solution that can range from transparent to slightly yellowish, with a pungent odor. This inorganic liquid is highly corrosive and is classified as a hazardous material under UN 1789, Class 8. Hydrochloric acid is generally transferred at concentrations between 32% and 36%, with the remaining portion consisting of water.
Due to its volatility and health risks, the safe handling of hydrochloric acid requires engineered transfer systems, airtight control mechanisms, and strict compliance with safety procedures.
Hydrochloric acid: where is it found?
Hydrochloric acid is widely used in industrial and commercial contexts. It is produced on a global scale and is found in:
- Chemical plants;
- Water treatment facilities;
- Oil and gas refineries;
- Food and beverage production plants;
- Pharmaceutical and biotechnological sectors;
- Metal pickling and steel processing operations.
