Asbestos Air Testing Objectives

Air testing is conducted for the following reasons:

  • Test for air contamination.
  • Ensure contamination does not occur outside an enclosed work area.
  • Check the effectiveness of respirators.
  • Ensure work area cleanliness.

All air testing is carried out by qualified air testing & monitoring professionals.

Clearance Testing

Measures if airborne asbestos concentrations are acceptable following disturbance of asbestos. Air testing is a regulatory requirement following asbestos abatement operations in many cases. Carried out to verify compliance with regulatory and guidance standards for the removal or disturbance of hazardous materials. Clearance testing is done by collecting representative air samples and submitting them for 3rd party accredited laboratory analysis. Removal of protective measures may not take place until the concentration of asbestos is acceptable. Control measures are in place to protect workers, building occupants, or others from asbestos.

Area Air Testing

Measures if asbestos is present in ambient air. Testing of air outside of an asbestos work area. The air testing can detect asbestos-laden air that may be leaking from an air tight containment.  Area air testing is often a requirement for government departments during construction. This type of screening is used by project owners/managers to ensure the protection of Site occupants located outside a work area.

Exposure Testing

Measures the exposure of an individual to asbestos, usually a worker. This type of testing is typically carried out to ensure that respirators worn by workers are providing the required level of protection.
