Abstract: Waste fluid containment and recovery apparatus for installation in-line with a piping system between a pair of horizontal interfacing flanges thereof. There is a pan having a bottom and surrounding sidewalls, the bottom having a bore therethrough. A flange interface having a pair of opposed interfacing surfaces which interface with respective ones of the pair of interfacing flanges is disposed around the bore for sealably connecting the bottom in line with the piping system. The floor can be sloped towards a drain and covered with a horizontal grating floor so that personnel can safely walk within the pan while fluids pass through the floor to the bottom below. Safety railings are removably attached around the sidewalls. One embodiment has support posts adjustably connected at the corners for supporting the pan over a well-head for attachment, removal, and against movement in use.

Abstract: This invention is a waste fluid containment and recovery apparatus for installation on the well-head of an oil well in-line with a pair of interfacing flanges thereof. There is a pan having a bottom and surrounding sidewalls. The bottom has a bore therethrough. There is also a flange interface having a pair of opposed interfacing surfaces which interface with respective ones of the pair of interfacing flanges disposed around the bore for sealably connecting the bottom of the pan in line with the well-head. A drain pipe is connected through the bottom for connection to a hose leading to waste fluid recovery apparatus.
