Abstract: A fluid containment device has a sleeve-like housing defining an inner chamber and an elongate slot or opening. At least one inner door is received in the inner chamber, and can rotate between a first retracted position (leaving the elongate slot open or unobstructed) and a second position (causing the elongate slot to be blocked or obstructed). With the inner door in the retracted position, the device can be quickly and efficiently positioned around a threaded connection existing between adjacent pipe sections. A safety door prevents undesired placement of body parts or other objects in the elongate slot (and in the path of the inner door) during powered rotation of the inner door. A variable diameter seal assembly is selectively closed around the outer surface of any pipe sections.
