A device is disclosed which acts to contain the contaminated effluent of an operation such as a hydro-blasting operation. The device has flexible bag for containing the effluent. The bag has an opening interfacing with a vessel being fluid blasted, into which opening the blasting effluent is received. A drain port is positioned on the containment bag to gravity empty the effluent from the interior of the bag, and a vent appropriately located on the containment bag to relieve pressure in the interior space during use and emptying. A flange strap disposed secures the bag opening to the vessel, and a support means is arranged to suspend the containment bag in proper relationship with the vessel. An expansion mechanism can be used to hold the containment bag in an expanded condition to facilitate use of the bag to properly contain the effluent.

What is claimed is: 1. A blasting fluid effluent containment device, comprising: a containment bag, including: a wall enclosing an interior space, and a throat having a leading edge defining a circular opening to accommodate an open end of a vessel; a flange strap to secure the throat to the vesse
What is claimed is: 1. A blasting fluid effluent containment device, comprising: a containment bag, including: a wall enclosing an interior space, and a throat having a leading edge defining a circular opening to accommodate an open end of a vessel; a flange strap to secure the throat to the vessel and seal the interior space; at least one support band, encircling the interior space, to support the containment bag in an expanded condition; at least one attachment point, connected to the support band, to suspend the containment bag; and a drain port. 2. The containment device of claim 1, further comprising a vent. 3. The containment device of claim 1, further comprising an overflow drain. 4. The containment device of claim 1, further comprising a draw string disposed at the leading edge of the throat. 5. The containment device of claim 1, wherein the containment bag is suspended in a horizontal orientation. 6. The containment device of claim 5, wherein said attachment point includes a pair of metal rings. 7. The containment device of claim 1, wherein the containment bag is made of flexible material and is water impermeable. 8. The containment device of claim 7, wherein the containment bag is a reinforced rubberized material. 9. The containment device of claim 7, wherein the containment bag is a poly nylon reinforced fabric membrane. 10. The containment device of claim 1, wherein the containment bag is substantially cylindrical. 11. The containment device of claim 10, wherein the circular opening is smaller than the cross-section of the interior space. 12. The containment device of claim 10, wherein the throat is removably-attached to the wall. 13. The containment device of claim 10, the wall is between 12 mils to 80 mils thick. 14. The containment device of claim 1, wherein the interior space has a substantially triangular cross-section. 15. The containment device of claim 2, wherein the vent is closable. 16. A method for containing blasting fluid effluent from a vessel using a containment device that includes a containment bag, a flange strap, at least one support band, at least one attachment point connected to the support band, and a drain port, the containment bag including a wall enclosing an interior space and a throat having a leading edge defining a circular opening to accommodate an open end of the vessel, the support band encircling the interior space, the method comprising: passing the throat over a flange of the open end of the vessel; tightening the flange strap to closely engage the throat around the flange and to seal the interior space to the vessel; suspending the containment bag using the attachment point; receiving the blasting fluid effluent; and emptying the blasting fluid effluent from the interior space. 17. The method of claim 16, wherein the containment bag includes a draw string and the method further comprises tightening the draw string to closely engage the leading edge around the vessel. 18. The method of claim 16, wherein the containment bag is suspended in a horizontal orientation. 19. A blasting fluid effluent containment device, comprising: a substantially cylindrical containment bag, including: a wall enclosing an interior space, and a throat, removably attached to the wall, having a leading edge defining a circular opening to accommodate an open end of a vessel; a flange strap to secure the throat to the vessel and seal the interior space; at least one attachment point to suspend the containment bag in a horizontal orientation; and a drain port.
