In the leak response sequence, which action is taken on the leak site after discovery before repair?

Explanation:
After a leak is found, cleaning the leak site is the essential first action. Removing oil, dirt, corrosion, and other residues ensures the surface is dry and uncontaminated so the repair material can bond properly and so the exact leak area can be accurately assessed. A clean surface also prevents contaminants from entering the system during the repair and helps reveal any additional damage that might need attention. Sealing is the actual repair action that stops the leak, coating is typically a later or different treatment, and dusting isn’t a standard preparatory step in leak response.
