ABSTRACT:
A sealed glove bag for containing and disposed of asbestos particles released during work on a pipe section is continuously ventilated by negative pressure applied at an exhaust port. An inlet port permits replacement ambient air to enter the bag and is provided with a HEPA-type filter to prevent asbestos particles from escaping via the inlet port. A similar filter may be placed at the exhaust port to prevent the particles from egressing via the exhaust port. In order to prevent collapse of the glove bag from the negative pressure, the bag is configured with a flat bottom and spaced walls, preferably in the form of a rectangular parallelepiped, that is reinforced with an insert configured to overlie the flat bottom and extend a short distance upwardly along the walls.
