What is the frequency of non-visual quantitative monitoring for pressurized product piping?

1. Every 3 hours

2. At least hourly

3. Once a month

4. Once a year

The correct answer is: At least hourly

The frequency of non-visual quantitative monitoring for pressurized product piping is at least hourly because this is crucial for maintaining safety and compliance within systems designed to transport liquids or gases under pressure. This monitoring ensures that any potential leaks or irregularities in the system can be detected promptly, minimizing risks associated with potential product loss, environmental hazards, and safety issues. Hourly monitoring allows for continuous oversight, making it possible to react quickly to any changes in pressure or flow that may indicate a problem. Given that pressurized piping systems can pose significant risks if left unchecked, a higher frequency of monitoring is essential. This standard reflects the need for vigilance in operations involving hazardous or flammable materials, which is governed by regulatory requirements to ensure the integrity of the piping systems.
