1. An apparatus for removing particulate matter from an enclosure having an internal space and an opening into the internal space, comprising:
a cover securable to the enclosure so that the cover covers the opening, the cover comprising multiple access ports;
a blower for establishing at a gas inlet of the blower a partial vacuum for drawing gas and particulate matter entrained therein from the internal space through an exhaust port open into the internal space and then through an exhaust conduit thereby maintaining a partial vacuum within the internal space; and
a lance connectable to a gas supply external to the enclosure for use;
wherein:
the lance is configured to be hand-held by a user outside the enclosure and comprises a lance valve operable by the user to vary flow of gas into the lance, and an elongate tube for direction of gas from the valve to an open end of the tube;
each access port is configured for insertion, by the user, of at least a portion of the elongate tube slidingly therethrough and to limit fluid movement into and out of the internal space both when the tube is received therein and when the tube is not received therein;
each access port is configured to permit the user, by manipulation of the lance, to vary both an orientation of the tube relative to the cover and an extent of penetration of the tube into the internal space;
wherein when the tube is slidingly inserted through any one or more of the access ports of the cover and the lance valve is operated by the user to enable the flow of gas into the lance, particulate matter within the internal space is dislodged by gas flowing from the open end of the tube, entrained in gas within the internal space and thereafter drawn from the internal space through the exhaust port and the exhaust conduit;
and wherein a hose end portion of the exhaust conduit is configured to be disconnectable from the exhaust port so that vacuum cleaning can be effected by the hose end portion being moved by the user into required locations as air is drawn into the end portion by the blower.
