Overfill Protection notifies the operator when the tank reaches which percentage of capacity?

1. 75% Capacity

2. 80% Capacity

3. 90% Capacity

4. 100% Capacity

The correct answer is: 90% Capacity

The correct answer is that overfill protection notifies the operator when the tank reaches 90% of its capacity. This standard is in place to prevent overfilling, which can lead to spills and environmental hazards. The 90% threshold allows operators enough time to take action to prevent an overflow before it occurs, thereby ensuring safe operations and compliance with regulations regarding the handling of underground storage tanks. When a tank reaches this level, the overfill protection system activates, typically triggering alarms or notifications to the operator. It is crucial to maintain this protocol as part of safety regulations aimed at minimizing risks associated with fuel storage. By monitoring the tank levels and responding promptly when 90% capacity is reached, operators can mitigate potential issues related to overfilling and protect both the environment and the facility.
