1. An apparatus for removing particulate matter from an enclosure having an internal space and an opening into the internal space, comprising:
a cover positionable adjacent the opening so that the cover covers the opening;
a gas source external to the internal space;
an inlet conduit that, when in use, extends through a specific first port in the cover and is adapted to direct gas from the gas source to at least one gas outlet within the internal space whereby particulate matter within the internal space is dislodged and entrained in gas within the internal space; and
a blower that draws gas and particulate matter entrained therein from the internal space through a second port opening into the enclosure then successively through an outlet conduit, a particulate matter separation and collection means comprising at least one filter, and into an inlet of the blower;
wherein:
the specific first port is one of a plurality of first ports in the cover;
the inlet conduit comprises an elongate lance having a first portion that includes the gas outlet and that a user in a workspace outside the enclosure can insert through the specific first port in the cover so that the gas outlet enters the internal space, the lance further having a second portion that then remains outside the internal space and is configured for manipulation by the user to move the gas outlet among locations within the internal space and to withdraw the lance from the specific first port for insertion into a further one of the plurality of first ports;
the apparatus further comprises a first sensor for sensing concentration of particulate matter in gas leaving the internal space;
the apparatus further comprises a second sensor that is on the second portion of the lance for sensing concentration of particulate matter in air at a location in the workspace outside the internal space; and
a visual display on the second portion of the lance;
and wherein:
the visual display is configured to display to the user in real time a concentration of particulate matter leaving the internal space sensed by the first sensor and is configured to display in real time a concentration of particulate matter in the workplace sensed by the second sensor while the apparatus is in use to alert the user in response to a detected excess value of particulate concentration in the workspace outside of the internal space while the lance is inserted into the internal space; and
wherein the visual display is configured to display to the user, in real time, information on functioning of the apparatus derived from additional sensors comprised in the apparatus.
