Which type of tank is designed for high-risk, volatile substances?

A double-walled tank is specifically designed to enhance safety and environmental protection when storing high-risk, volatile substances. This design consists of an inner tank, which holds the substance, and an outer tank that acts as a secondary containment measure. The space between the two walls can capture any leakage or spillage from the inner tank, preventing hazardous materials from escaping into the environment. This feature is particularly critical for volatile substances that could pose a significant risk of fire, explosion, or contamination if not properly managed.

In contrast, single-walled tanks do not offer the same level of protection, as they lack the secondary containment layer. Plastic tanks may be suitable for certain applications but are not necessarily designed for high-risk hydrocarbons and volatile chemicals, which often require more robust materials and construction methods. Above-ground tanks can be either single or double-walled and, depending on their construction, may or may not provide adequate protection against leaks and spills, making them less reliable for high-risk substances when not specifically designed as double-walled.
