Is it true that an overfill alarm is not capable of shutting off the flow of product during fuel delivery?

An overfill alarm is designed to alert operators to prevent the tank from reaching an overflow condition during fuel delivery. However, while it provides an important safety notification, it does not have the capability to automatically shut off the flow of product. Instead, the responsibility rests on the operators to respond to the alarm and take appropriate action to stop the flow of fuel manually. This underscores the importance of operator training and vigilance during fuel deliveries to ensure adherence to safety protocols and regulatory requirements.

Other options may imply varying functionalities of overfill alarms or situational dependencies, but the fundamental role of an overfill alarm is to serve as a warning system rather than a flow control mechanism. Hence, it's crucial for operators to understand this distinction and not rely solely on alarms for managing fuel deliveries.
