Consideration needs to be given to whether the diesel is used in connection with an oil burning installation, an internal combustion engine such as a generator, or a dispenser for retail sale, as this will impact the controls required.

Some of the controls for diesel that may be required include secondary containment, fire extinguishers (none required at unattended service stations for diesel fuel and biodiesel), emergency response plans and stationary container certification (quantity greater than 5,000 litres in an above ground tank).
