California ICC UST Service Technician Practice Exam

Which of the following is a requirement for tanks used to store hazardous materials?

1. They must be made of aluminum

2. They must have secondary containment

3. They must only be above ground

4. They must be fitted with plastic liners

The correct answer is: They must have secondary containment

The requirement for tanks used to store hazardous materials includes the necessity for secondary containment. Secondary containment refers to a system designed to contain leaks or spills from the primary storage tank to prevent environmental contamination. This is crucial in ensuring that hazardous materials do not escape into the surrounding area, thereby safeguarding both public health and the environment. The use of secondary containment systems is mandated in various regulations to mitigate the risks associated with hazardous materials storage. These systems can include dikes, berms, or double-walled tanks, providing an additional layer of protection. Regarding the other options, aluminum is not universally mandated for tank construction, as materials can vary depending on the specific regulations and the hazards associated with the stored material. Tanks can be above ground or below ground in specific applications, depending on regulatory requirements and environmental considerations. Plastic liners can enhance containment but are not a universal requirement for all tanks storing hazardous materials. Thus, secondary containment stands out as a foundational regulatory requirement to effectively manage the potential risks of leakage or spill from hazardous material storage.
