California ICC UST Inspector Practice Exam

When must tanks lined to meet upgrade requirements be inspected by a coatings expert?

1. Before being returned to service

2. Within 5 years of lining

3. After each filling

4. All of the above

The correct answer is: Before being returned to service

The correct answer highlights the crucial step of ensuring the integrity and effectiveness of the tank lining before the tank is returned to service. Inspections by a coatings expert are necessary to verify that the new lining adheres properly, is free from defects, and meets all regulatory and safety standards. This inspection is a preventative measure that helps avoid potential leaks or failures that could lead to environmental contamination and safety hazards. The emphasis on inspection before the tank is put back into use underlines the importance of maintaining stringent quality control in storage tank operations. After all, a well-inspected and properly lined tank contributes significantly to the safety and environmental responsibility of the facility. While other options may seem reasonable, they do not specifically capture the immediate necessity for an expert inspection prior to returning the tank to operational status. Inspections after filling or within a set timeframe following lining do not provide the same level of assurance before the tank is actively being used again.
