Abstract
A fire resistant composite intermediate bulk container for holding flammable liquids is provided. The composite IBC has an inner polyethylene container surrounded on at least its vertical sides by a protective metal cage. The protective metal cage is coated with an intumescent paint or other intumescent coating. When the intumescent coating is exposed to high temperatures, such as could occur during a fire, the coating swells and chars, producing an ash that insulates the metal cage, preventing it from heating up to the point where it can melt through the polyethylene container.
