What must you do before starting corrosion removal?

• A. Run a standard corrosion removal procedure
• B. Apply chemical corrosion inhibitors first
• C. Conduct an inspection and evaluation of the suspected area
• D. Ignite dehydration solvent

Answer: (C)

Before starting corrosion removal, you must perform a thorough inspection and evaluation of the suspected area. This initial assessment reveals the extent and type of corrosion, the materials and coatings involved, access and confinement issues, environmental and safety hazards, and the most appropriate method for removal. By understanding these factors up front, you can select the correct technique (mechanical, chemical, or other), determine required containment and PPE, and plan permits and disposal. This planning step prevents applying an ill-suited method, uncovers hidden damage, and reduces safety risks.

The other options don’t fit because they skip the essential assessment. Running a standard removal procedure without tailoring it to the specific conditions can lead to ineffective results or damage. Using chemical inhibitors before removal is a protective measure for in-service conditions, not a pre-removal step. Igniting a dehydration solvent is dangerous and irrelevant to proper corrosion removal.
