Definition - What does Corrosion mean?
Corrosion takes place when materials are broken down through oxidation. It is most often used to describe the chemical reaction involved in the breakdown of refined metals to their oxides, but is occasionally used to refer to the degradation of ceramics and polymers. Corrosion affects the integrity of materials, weakening them and affecting other properties like their permeability to liquids or gases. The term can also be applied to gases and liquids that may cause injury by corroding skin on contact.
Safeopedia explains Corrosion
Corrosion of metals and other materials can cause significant workplace injuries and accidents owing to resulting equipment failure. During inspections, corrosion is regarded as sufficient cause for discontinuing the use of equipment or recommending partial replacement where this is possible. With reference to chemicals, the handling and use of corrosive materials requires specific safety precautions including, but not limited to, the use of personal protective equipment (PPE) such as gloves, coveralls and eye protection. Risk assessments and inspections should include attention to the safe storage and containment of corrosive chemicals.
