Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
A corrosive material is a liquid or solid that causes full thickness destruction of human skin at the site of contact within a specified period of time. A liquid that has a severe corrosion rate on steel or aluminum based on the criteria in 49CFR 173.137(c)(2) is also a corrosive material .
They are highly effective in preventing salt water and hydrogen sulfide (H2S) corrosion. Acrylic polymers: These polymers are used as corrosion inhibitors in the industry due to their good compatibility with oil and drilling fluids. They are effective against corrosion caused by the presence of hydrochloric acid (HCl) in drilling fluids.
The chemical substance hydrochloric acid is the aqueous (water-based) solution of hydrogen chloride (H Cl) gas. It is a strong acid , the major component of gastric acid and of wide industrial use. As a highly corrosive liquid , hydrochloric acid should be handled only with appropriate safety precautions.
Hydrogen chloride forms corrosive hydrochloric acid on contact with water found in body tissue. Inhalation of the fumes can cause coughing , choking , inflammation of the nose, throat, and upper respiratory tract , and in severe cases, pulmonary edema , circulatory system failure, and death. [ 26 ]
Hydrazoic acid: used primarily for preservation of stock solutions, and as a reagent Hydrochloric acid: a highly corrosive, strong mineral acid with many industrial uses Hydrofluoric acid: valued source of fluorine, precursor to numerous pharmaceuticals; highly corrosive Hydrogen peroxide: an oxidizer commonly used as a bleach Imidazole
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids. [3] [4] [5] Operators are required to disclose the content of hydraulic fracturing fluids to the relevant environment agency [6] while the composition must be disclosed if the regulator demands it.

Water-based drilling fluid has very little toxicity, made from water, bentonite and baryte, all clay from mining operations, usually found in Wyoming and in Lunde, Telemark. There are specific chemicals that can be used in water-based drilling fluids that alone can be corrosive and toxic, such as hydrochloric acid.
