Overview

Painting Inspection is a specialized field that is usually assigned to an outside consultant. The following areas represent critical items that must be monitored.
1. Pre- construction review
• Check specifications for surface preparation
• Check paint system
• Determine the work that will be measured (An example is welding repair. If there are a lot of repairs based on the pre design inspection, it will have a per inch unit cost. If it is minimal, it will considered incidental work)
2. Taking the Tank out of Service
• Coordinate with Operations
• Remember entering an empty tank is a confined entry procedure
• Verify that the electric service is locked out
• Verify that fill valves are closed and in manual mode
• Verify that the tank is clean unless cleaning is part of the contractor’s work
3. Surface preparation
• Monitor for paint chips leaving the site
• Observe the surface condition for compliance
4. Surface preparation with lead paint
• Review the lead paint test results
• Obtain additional samples to verify lead hazard level
• Check containment provisions to keep lead based paint from leaving the site
• Obtain copies of the hazardous waste manifest to verify proper disposal
5. Coating application
• Verify that the product on site matches the specification
• Verify that the application method is suitable for the product on site
• Measure the air temperature, humidity, and surface temperature for compliance with the application specifications and product recommendations
• Monitor the product application and record the approximate area and location applied per session
• Check the dry film thickness
• Verify drying time between coats
• Monitor the next coats as above
• Conduct spark tests and mark failures
• Recheck failures
6. Prepare for disinfection
• Verify that all cathodic protection equipment is installed inside the tank
• Check tank for tools and/or other items that do not belong in the tank and remove
• Close all access ports
• Fill tank according to the disinfection procedure
• Pull bacti samples
• Check bacti results for proper disinfection
• Inform Operations that the tank is ready to be put in service if bacti tests pass.
