California UST System Operator Practice Test

The correct choice emphasizes the importance of adhering to both established codes of practice and the manufacturer's instructions when installing UST (Underground Storage Tank) systems. This dual adherence is crucial for ensuring that the installation is both safe and compliant with regulatory requirements.

Codes of practice provide general guidelines that reflect industry best practices and are often developed with input from experts in safety, engineering, and environmental protection. Meanwhile, following the manufacturer's instructions ensures that the specific tank system is installed in a manner that aligns with its unique design and operational specifications, which the manufacturer has tested and approved.

Together, these elements help to mitigate risks such as leaks or environmental contamination, ensuring that the UST system operates as intended while conforming to regulatory standards. The collaboration of these guidelines is vital for promoting safety and compliance in UST installations, aligning with the overall goal of protecting public health and the environment.

Other options, while they address important aspects of system installation, do not encompass the comprehensive approach needed for UST systems. Accessing only industry standards or local building codes may not provide the full set of requirements necessary for safe operation. Relying solely on safety regulations without the additional context from manufacturer specifics or broader codes of practice could lead to gaps in safety or compliance.
