What does the term “clearance testing” refer to?

Clearance testing refers to air monitoring conducted after asbestos abatement work has been completed to ensure that the levels of asbestos fibers in the air are safe for reoccupation. This process is crucial in confirming that all hazardous materials have been adequately removed and that the environment is safe for occupants. The testing typically involves collecting air samples and analyzing them for the presence of asbestos fibers. Only when the results indicate that the fiber levels are below regulatory limits can a work area be declared safe, allowing for reentry and use. The focus on confirming safe fiber levels is essential to protect the health and safety of individuals who may occupy the space after remediation.
