The main cause of chemical burns is from contact with strong acids or bases. The strength of acids and bases is defined by the pH scale, which ranges from 1-14. A very strong acid has a pH of 1 and may cause a severe burn. A very strong base has a pH of 14 and may also cause a severe burn. A substance with a pH of 7 is considered neutral and does not burn. Chemical burns from acids or bases are also referred to as caustic burns.
Chlorine Chemistry. Chlorine is the predominant method of disinfecting water and wastewater and has been used for almost 100 years in the United States. Chlorine can be added to water as chlorine gas, an aqueous sodium hypochlorite solution, or solid calcium hypochlorite. When chlorine is added to water in any of these forms, it creates hypochlorous acid.
