AMPP CCI-2 case studies
AMPP CCI-2 · Put your knowledge to work in context.
The AMPP Coating Inspector Certification program is administered by AMPP, The Association for Materials Protection and Performance, which describes itself as the largest global community for corrosion and coatings expertise. Within that program, the CCI Level 2 credential (also written CCI-2) is the second tier of coating inspector certification, positioned beyond the entry level for inspectors who already have field or shop experience and want their competence formally recognized. The AMPP CCI-2 case studies are 5 cases and about 2,816 words.
1Spot the Soluble Salt Risk Before Blasting
A bridge rehabilitation crew is scheduled to abrasive-blast 4,200 m² of heavily rusted structural steel. The structure sits 60 m from a tidal estuary, and the previous coating has been removed by the owner's prior contractor.
