A method and apparatus for the containment of dust within a bulk cargo container such as a ship or barge hold. A horizontal stream of ambient air is directed across the hatch opening by a plurality of interconnected air curtain modules which captures fugitive dust along its path. A plurality of interconnected dust collector modules withdraw the entrained dust particles at an opposite side of the hatch opening and exhaust the filtered air stream therefrom and deposit the filter cake back into the hold. The clean exhaust air from the dust collector modules may be used to form a vertical air curtain to deflect crosswinds.

A method for containing dust-like particulate material within the hold of a bulk cargo container during loading and unloading operations, said method comprising the steps of: establishing a plurality of spaced-apart, coherent primary air streams at one side of an open hatch of said cargo hold and directing said primary air streams across the top of said cargo hold along a substantially horizontal pathway, each of said primary air streams creating a secondary air stream therearound which gradually diverge, forming a substantially continuous stream of air across the top of the cargo hold; capturing fugitive, dust-like particulate material and entraining said particulates within said horizontal stream of air; collecting said horizontal stream of air and said entrained particulate material at an opposite side of said cargo hold from said source of primary air streams; filtering said entrained particulate material from the horizontal air stream; exhausting said filtered air stream to the atmosphere; and returning said collected particulate material to said cargo hold.
