California ICC UST Service Technician Practice Exam

Which method is considered INCORRECT for documenting piping location according to PEI RP 300?

1. Using GPS coordinates

2. Sketching a diagram on the inside cover of vapor recovery equipment manual

3. Maintaining a written report

4. Taking photographs of the installation

The correct answer is: Sketching a diagram on the inside cover of vapor recovery equipment manual

The choice of sketching a diagram on the inside cover of the vapor recovery equipment manual is considered incorrect for documenting piping location according to PEI RP 300 for several reasons. This standard emphasizes the importance of formal documentation that is easily accessible, consistent, and maintained in a way that supports regulatory compliance and operational safety. Using GPS coordinates, maintaining a written report, and taking photographs of the installation are all methods that provide clear, precise, and retrievable information. GPS coordinates allow for exact location specifications, which is crucial for future reference, maintenance, and inspections. A written report offers a structured way to document details in a standardized format, enhancing clarity and ensuring that information is available when needed. Photographs serve as visual confirmation of the installation and can capture details that written descriptions may miss. In contrast, sketching a diagram on the inside of a manual can lead to issues such as loss of that specific document, challenges in locating the information later, or inconsistency if multiple copies of the manual exist. Formal documentation methods not only improve retention and accessibility but also foster compliance with legal and safety regulations, making the other options more reliable and acceptable for proper documentation.
