An oil tank is a container designed to store oil, typically used for heating or fueling purposes. These tanks can be found in residential, commercial, and industrial settings, holding various types of oil, including heating oil and diesel fuel. They come in different sizes and materials, such as steel or plastic, to suit specific needs and regulations. Oil tanks are often installed above or below ground, depending on local laws and space availability. Proper maintenance and regular inspections are essential to prevent leaks and ensure safety. Additionally, many regions require environmental regulations to minimize the risk of contamination from oil spills.
