An auxiliary tank shall not exceed how many gallons?

The correct answer is based on the regulatory standards governing auxiliary tanks in petroleum service. According to the Maine Oil Fuel Board regulations, an auxiliary tank is defined as a tank that is used to supply fuel only to a single burner system, and these tanks are limited in size to ensure safety and minimize the risk of spills and accidents.

Specifically, the limit of 60 gallons establishes a balance between providing adequate fuel supply and maintaining manageable risks associated with fuel storage. This restriction helps ensure that any potential leak or failure presents a minimized hazardous incident, supporting safety practices in residential and commercial installations.

Understanding this regulation is crucial for oil fuel handlers and those involved in the installation of heating systems, as compliance with these limits is enforced to protect both the environment and public safety. Therefore, recognizing the significance of the 60-gallon limit aligns with best practices in fuel management.
