Abstract: Articles of manufacture, systems, and methods relating to a liquid containment panel are provided, where the liquid containment panel includes a body comprising a thermoplastic olefin. The body has a substantially horizontal portion and a substantially vertical portion and is configured to be freestanding with the substantially vertical portion in an upright position. One or more coupling features can be located along one or more edges of the body, where such coupling features can couple the liquid containment panel to another liquid containment panel to form a barrier or containment system.
