What is the main aim of under-dispenser containment?

The primary aim of under-dispenser containment is to prevent fuel spills and leaks. This containment system is designed to capture any product that may escape from the dispenser or the associated piping, thereby protecting the environment and mitigating the risk of fire hazards. By providing a physical barrier, under-dispenser containment helps ensure that any accidental release of fuel is contained within a designated area, which can then be monitored and managed appropriately. This is essential for complying with environmental regulations and maintaining safety standards in fueling operations.

The other options reference aspects that are not the primary focus of under-dispenser containment. For instance, enhancing physical security pertains to preventing theft or vandalism, which is a separate concern from managing fuel spills. Improving aesthetics, while important for customer perception, does not directly relate to the critical function of preventing environmental damage. Increasing pump efficiency mainly involves performance optimization and not the containment function itself.
