Can red tagged fill pipes (risers) receive fuel deliveries?

1. Yes

2. No

3. Only in emergencies

4. Only with special permission

The correct answer is: No

Red-tagged fill pipes indicate that there is a safety concern or compliance issue associated with the piping system that prevents it from being used safely for fuel deliveries. When fill pipes are red-tagged, it serves as a warning that they are not to be utilized until the identified problems have been properly addressed and rectified. This protocol is in place to ensure the safety of personnel, the integrity of the storage tank system, and to prevent environmental hazards that could occur from a potential leak or failure of the infrastructure. Consequently, filling a red-tagged pipe with fuel would pose serious risks and violate safety regulations, making it imperative that such pipes remain non-operational for fuel deliveries until they are inspected and subsequently cleared for use. This is why the option stating that red-tagged fill pipes cannot receive fuel deliveries is correct.
