California ICC UST Inspector Practice Exam

Where is a red tag typically applied?

1. On the turbine head

2. On the fill tube

3. On the dispenser hose

4. On the cash register

The correct answer is: On the fill tube

A red tag is typically applied to the fill tube on a UST (Underground Storage Tank) system. This tag serves as a crucial indicator that there is a problem associated with the tank or its components, particularly related to filling operations. The fill tube is instrumental during the refueling process, and if a red tag is issued, it signifies that the area or equipment presents an unsafe condition or that it is out of compliance with regulations. This allows for a visual alert for operators and inspectors so that they can take necessary precautions before any further use or filling occurs. Applying the tag here is a proactive safety measure to prevent accidents, spills, or breaches that could result from a malfunctioning fill tube. It stands as a warning that immediate action or repair is needed before the tank can be safely filled again. Options referencing the turbine head, dispenser hose, or cash register would not typically be associated with a red tag, as they do not directly indicate an issue with the filling process relevant to the UST's operation and safety compliance.
