Korrozív

Korrozív is a term used to describe substances that can cause irreversible damage to living tissue or to materials through chemical action. In English, the closest equivalent is corrosive. Corrosives can degrade metals by dissolution or oxidation and can burn skin, eyes, or mucous membranes on contact. The severity of harm depends on concentration, exposure time, and the route of exposure.

Common categories include acids (for example sulfuric acid, hydrochloric acid), bases or caustics (such as sodium hydroxide, potassium hydroxide), and certain oxidizers or dehydrating agents. They may act by protonating, hydrolyzing, oxidizing, or dehydrating tissue and materials, sometimes releasing heat rapidly.

Hazards: corrosives can cause severe burns, eye damage, respiratory irritation, and tissue destruction. Inhalation of fumes can injure the lungs; ingestion can cause internal damage. They can also corrode equipment, pipes, and containers, potentially leading to leaks or hazardous reactions with incompatible substances.

Safety and handling: use appropriate personal protective equipment, including chemical-resistant gloves, goggles or a face shield, and protective clothing. Work in well-ventilated areas and store indoors away from incompatible materials such as oxidizers, acids with bases, or reactive metals. Use corrosion-resistant, compatible containers and clearly label all containers. Follow local regulations for hazardous materials storage and disposal.

First aid: if contact occurs, rinse exposed skin or eyes with running water for at least 15 minutes and remove contaminated clothing. For inhalation, move to fresh air. For ingestion, seek medical attention and do not induce vomiting unless advised.
