👉 Salt fumes are a hazardous byproduct of the electrolysis of sodium chloride (table salt) or halite, typically occurring when large quantities of salt are exposed to air and water. This process involves passing an electric current through a concentrated salt solution, causing the chloride ions to separate and react with oxygen, producing sodium hydroxide gas and, more importantly, chlorine gas. The chlorine gas then reacts with water vapor in the air to form hydrochloric acid and sodium hypochlorite (bleach), both of which can release harmful salt fumes. These fumes are characterized by a pungent, acrid smell and can contain toxic chlorine compounds, posing significant health risks such as respiratory irritation, eye damage, and even respiratory failure if inhaled in sufficient quantities. Proper ventilation and protective equipment are essential when handling or exposing oneself to salt fumes.
