California Designated Operator Practice Exam

Which of the following actions must take place before putting a new tank into service?

1. Complete an integrity test

2. Paint the exterior

3. Install signage

4. Calibrate measurement tools

The correct answer is: Complete an integrity test

Before a new tank can be put into service, it is essential to conduct an integrity test. This procedure ensures that the tank is structurally sound, has no leaks, and is safe to hold the intended contents. The integrity testing process can include pressure tests or other methods that assess the tank's ability to maintain its design specifications under operational conditions. Conducting this test is a vital step in compliance with safety regulations and helps prevent potential environmental hazards or hazardous material spills occurring once the tank is in use. While painting the exterior, installing signage, and calibrating measurement tools are important maintenance and safety practices, they do not directly verify the tank's structural integrity. Without confirming that the tank is safe for use, all other preparatory actions would be rendered ineffective; thus, ensuring the tank's integrity is paramount before it is placed into operation.
