In the risk assessment sequence, which step logically follows 'evaluate corrosion mechanisms'?

• A. Rank risk
• B. Plan monitoring
• C. Estimate potential rates
• D. Identify assets

Answer: (C)

Quantifying how fast corrosion could occur is the next essential step after identifying which mechanisms could drive degradation. Once you know the possible mechanisms, estimating potential rates translates those mechanisms into a measurable threat under the actual conditions the asset experiences. This rate information is what lets you gauge the severity and likelihood of failure, turning qualitative ideas into numbers you can compare across assets and scenarios. With estimated rates in hand, you can rank risk and determine where monitoring and mitigation are most needed. The step of identifying assets typically occurs earlier to define what you’re protecting, and planning monitoring follows after you’ve prioritized risks.
