Claim:
1. A method of reducing the release of harmful respirable particles through at least one opening on a top surface of a truck containing sand in a bin of the truck, the method comprising: securing a filter-receiving member to the truck at a location adjacent to the at least one opening in the top surface of the truck, the act of securing the filter-receiving member including positioning one or more securing members below the top surface of the truck and positioning a compressible material between the top surface of the truck and a portion of the filter-receiving member to create a seal that restricts the movement of harmful respirable particles between the top surface of the truck and the filter-receiving member, the filter-receiving member comprising a first side, a second side, and a passageway extending from the first side to the second side; attaching a filter member to the filter-receiving member and a vertical support member such that it extends vertically upward from the top surface of the containment area in the vehicular equipment, the filter member with a porosity that permits air to flow through the filter member and restricts the flow of solid particulates; opening a gate member between the filter-member and the bin to permit air flow to the filter member from the bin; pressurizing the bin to form a filter cake on an inside surface of the filter member to improve mechanical filtration of the filter member; and cycling the filter member through pressurization and depressurization cycles to adjust an amount of the filter cake formed on the inside surface of the filter member.
