The containment device constructed according to a preferred embodiment of the invention includes a rectangular base formed of an impermeable material, a deformable wall formed along a first set of opposable ends of the rectangular base, and a support wall formed along at least a portion of a second set of opposable ends of the rectangular base. The deformable wall has an upright configuration in which the deformable wall is capable of containing hazardous materials within the containment device, and a deformed configuration enabling wheeled vehicles to pass over the deformable wall to enter and exit the containment device. The support wall includes rigid upright support members maintaining the support wall in an upright position and, preferably, additional rigid hypotenuse and base members that coact with the upright support members to form right triangles anchored to a skirt affixed to the base of the support wall.
