An Abatement activity has many intricate parts. The size of the area being worked on, for the correct negative pressure to be used. The negative air pressure machine (High Efficiency Particulate Air (HEPA))moves fresh air into the work area while trapping the asbestos (airborne) in a series of filters before exhausting clean air out the exhaust of the unit. Removal always requires wetting the material being removed with an amended water solution thus keeping the air/fiber concentration down to a minimum. Asbestos fibers are aero dynamic and can stay airborne indefinitely with air movement.
