Final answer:
The acceptable methods for testing the product tightness of tanks installed after July 1, 2003, include visual inspection, pressure testing, ultrasonic testing, and dye penetrant testing.
Step-by-step explanation:
The acceptable methods for testing the product tightness of tanks installed after July 1, 2003, according to the health and safety code, are:
- Visual inspection: This involves visually examining the tank for any visible leaks or cracks.
- Pressure testing: This method involves pressurizing the tank and monitoring for any pressure drops, which would indicate a leak.
- Ultrasonic testing: This method uses ultrasonic waves to detect any leaks or structural defects in the tank.
- Dye penetrant testing: This test involves applying a dye to the tank's surface and then inspecting it for any signs of dye penetration, which would indicate a crack or leak.
