Abstract
A fluid containment apparatus with a floor and a side wall is provided. A wall support is included that supports the side wall and can be moved between an initial supporting position and a collapsed position. The side wall is movable from an initial containment position to a collapsed state to allow access for vehicles or other objects to the floor. The wall support and side wall are subsequently movable back to their initial positions. In some arrangements, the wall support is movable back to the initial supporting position from the collapsed position but is not movable beyond the initial supporting position. Additionally or alternatively, in other embodiments the wall support remains in the collapsed position until a returning force is applied to move the wall support back.
