Abstract: A containment device is provided that includes a bottom tray (20) that is of cylindrical shape having a lower surface and one open end. The lower surface has a hole (26) disposed therethrough which is operable to be disposed about a flange on a wellhead with a seal (32) formed between the outer peripheral edges of the hole (26) and the peripheral edge (14) of the flange (12) on the wellhead. The stuffing box (16) will have leaks therefrom collected in the bottom of the tray (20). A cowling (20) is disposed about the stuffing box (16) and supported on a shelf (36) to maintain an amount of any fluid in the bottom of the tray (20). Cap (22) is disposed over the cowling with a hole (38) disposed in the upper surface thereof to allow the polish rod (18) to extend therethrough. An orifice (42) is operable to allow fluid to escape from the tray (20). Each of the bottom tray (20), cowling (24) and the cap (24) are split to allow assembly over and around the wellhead.
