What is a common sign of a malfunctioning vapor recovery system?

• A. Decrease in fuel vapor smells at the station
• B. Increase in fuel vapor smells at the station or observed vapors during fueling
• C. Consistent fuel delivery times
• D. Regular maintenance alerts

Answer: (B)

A common sign of a malfunctioning vapor recovery system is an increase in fuel vapor smells at the station or observed vapors during fueling. This indicates that the system is not effectively capturing and recovering the fuel vapors that are supposed to be managed during the fueling process. A well-functioning vapor recovery system should minimize any releases of fuel vapors into the atmosphere, thereby reducing odors and potentially harmful emissions.

When vapors are not adequately contained and instead escape into the atmosphere, it signals that the equipment might be damaged, improperly installed, or not functioning correctly. This condition not only creates unpleasant odors, but it can also pose health risks to customers and employees and contribute to environmental pollution. Therefore, an increase in these vapors is a clear indication that immediate attention and repair may be necessary to restore the proper functioning of the vapor recovery system.
