Hazardous substances are considered corrosives if they have the ability to eat through metal, burn human or animal skin upon contact and exude vapors or fumes that can cause stinging or burning sensation to the eyes. Examples of hazardous substances that are corrosive are:
Fluoroantimonic Acid - This is also known as super acid because of its strength and capability to burn through anything, including substances that are not supposed to react to acid. It is a combined mixture of antimony pentafluoride and hydrogen fluoride. According to research studies, it is said to be 20 quintillion times more potent than sulfuric acid. This super acid can be found in industries that require chemical reactions in order to achieve transformation, as in the refinement of crude oil into high-octane gasoline or the transformation of oil shale into crude oil. They can also be found in industries involved in the manufacture of plastics.
Hydrochloric Acid - is commercially known as muriatic acid and is considered to be one of the most versatile and important chemical compound in manufacturing industries. Hydrochloric Acid is chlorine gas burned in hydrogen to produce hydrogen chloride (HCl). HCl, when combined with water, will release hydronium ions to form hydrochloric acid and become commercially available into two grades; the technical grade, which has concentrations of 35-38% and the commercial grade known as muriatic acid, with concentrations of 30-32%. In industries, the technical grade is used in metals, electroplating, in activating geothermal oil wells, processing of electronic products and manufacture of fertilizers and dyes. In the food industry, HCl is used for processing starch, glucose and protein. Muriatic acids are popularly used in households as effective stain removers for floor tiles as well as other kitchen and bathroom fixtures.
Sulfuric Acid - This substance is also known as oil of vitriol or vitriol and is industrially processed by dissolving sulfur trioxide in water. Once it is made to reach saturation point, it becomes fuming sulfuric acid known as oleum to be used in processing other organic chemicals. Sulfuric acid is also considered one of the most important chemicals in industrial sectors utilized in manufacturing dyes, pigments, fertilizers, detergents, explosives, inorganic salts and acid. It is also the main acid substance in lead-acid storage batteries. Other uses can be found in the petroleum refining industries and metallurgical processing.
Nitric Acid - This hazardous substance is highly corrosive, can have the properties of fuming corrosive liquid and is considered an inorganic compound. Its importance can be found in industries involved in the manufacture of fertilizers and explosives, as well as in the reprocessing of spent nuclear fuel. It is commercially used for steel etching and photoengraving.
