What is meant by excessive corrosion during inspections?

Excessive corrosion during inspections refers to significant deterioration of materials, which can have serious implications for the integrity and safety of structures or equipment. This level of corrosion indicates that the protective mechanisms have failed, leading to more than just superficial damage. It suggests a considerable loss of material due to chemical reactions with moisture, oxygen, and other environmental factors, which can compromise the strength and functionality of the affected items.

In contrast, minor rust on fixtures is a sign of early-stage corrosion that may be manageable with proper maintenance, and surface discoloration only does not imply that there has been any substantial degradation of the material itself. Similarly, issues limited only to paint do not encapsulate the potential structural risks associated with corrosion, as painting could simply mask underlying deterioration rather than addressing it. Therefore, identifying excessive corrosion focuses on the serious and potentially structural impacts rather than superficial changes.
