A containment bag for installation over a fluid control valve is provided. The valve containment bag is configured to contain leaks emanating from fluid control valves connected in line between an associated first inlet pipe and a second outlet pipe. The inlet pipe and the valve form a first junction and the outlet pipe form a second junction which are to be housed, along with the valve itself, within said bag so that fluid leaking from the junctions leaks into the containment bag. The containment bag is formed of an impermeable fabric which encloses an internal volume sufficient to accommodate the control valve and the associated junctions. The impermeable fabric defines first and second openings between the internal volume and the external environment, the first opening has a diameter substantially equal to the outer diameter of the inlet pipe, and the second opening has a diameter substantially equal to an outer diameter of the outlet pipe. A re-sealable seam extends between the said first and seconds openings so that the bag may be opened and installed over a previously installed control valve. The re-sealable seam may then be re-sealed to close the containment bag, with said first pipe protruding from said first opening and said second pipe protruding from said opening.
