corrosive

Corrosive describes a substance that can damage or destroy other materials through chemical action. This typically involves acids and bases that attack metals, skin, eyes, and organic matter, but can also include oxidizing agents and certain salts. Corrosion is the deterioration of a material caused by chemical reactions with its environment.

In chemical terms, acids donate protons and react with metals to form salts and hydrogen gas, while strong bases can saponify fats and denature proteins in tissue. Rate of corrosion depends on concentration, temperature, exposure time, and the presence of water or oxygen.

Hazards: Substances labeled corrosive can cause severe chemical burns, blindness, or respiratory damage on contact or inhalation. They may also corrode and weaken metal equipment. Safe handling requires appropriate personal protective equipment, engineering controls, and proper storage away from incompatible materials.

Regulatory notes: Corrosives are classified under hazard class 8 in many safety frameworks, and signals such as GHS labels indicate corrosivity. Safety data sheets provide handling guidelines, first aid steps, and environmental precautions. Storage typically uses corrosion-resistant containers and segregation from acids, oxidizers, and reactive metals.

Common uses include metal cleaning and etching, battery and electrolyte solutions, and various industrial processes. While useful, corrosives demand careful risk management to prevent injury and damage to infrastructure.
