After Asbestos Removal or Abatement
Clearance testing is performed after the completion of asbestos removal or abatement activities to ensure that the area is safe for reoccupation. This is crucial to confirm that airborne asbestos fiber levels have been reduced to acceptable levels.
Before Reoccupying an Area
Clearance testing is done before allowing occupants to return to a building or area where asbestos removal or abatement work has been performed. It provides assurance that the environment is free from hazardous asbestos fibers.
Following Remediation Activities
In cases where asbestos-containing materials have been disturbed due to renovation or other activities, clearance testing may be required to verify that the cleanup and containment efforts have been effective in preventing asbestos fiber release into the air.
During Demolition Projects
When demolishing structures that may contain asbestos, clearance testing may be necessary to ensure that the demolition process has not released asbestos fibers into the surrounding environment, particularly in areas where the demolition has disturbed asbestos-containing materials.
Clearance testing may be mandated by local or national regulatory agencies as a requirement for obtaining permits or certifications related to asbestos removal, abatement, renovation, or demolition activities.
