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.
Chlorine is a strong oxidizing element causing the hydrogen to split from water in moist tissue, resulting in nascent oxygen and hydrogen chloride that cause corrosive tissue damage. Additionally oxidation of chlorine may form hypochlorous acid, which can penetrate cells and react with cytoplasmic proteins destroying cell structure.

A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...

The use of personal protective equipment may substantially reduce the risk of adverse health effects from contact with hazardous materials. [2] Long-term exposure to chemical hazards such as silica dust, engine exhausts, tobacco smoke, and lead (among others) have been shown to increase risk of heart disease, stroke, and high blood pressure.

An acidic solution — generally hydrochloric acid — is used to separate the gold from the carbon. The gold-laden liquid is poured over electrified steel, which attracts flakes of the metal. Heavy metals are a byproduct of refinement. In 2000, a cask of mercury leaked in transit from the Yanacocha mine, sickening nearly 1,000 people.
Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the ...
