When do I need an asbestos inspection? 


If an owner of a public or commercial building will be disturbing any building materials during the course of his or her renovation or demolition, the owner is required to have the materials surveyed for asbestos by a licensed asbestos professional. A survey is required regardless of the age of the building. 

What is an asbestos contractor supervisor?


This Asbestos Contractor Supervisor is any individual who performs supervision of persons permitted to enter the restricted and regulated asbestos abatement work area. The supervisor is also responsible for performing the duties of the OSHA competent person for the asbestos project, consistent with current EPA and OSHA regulations. An Asbestos Contractor Supervisor must have a valid certificate with them at all times while working on qualifying projects. 


Exposure to asbestos increases your risk of developing lung disease. That risk is made worse by smoking. In general, the greater the exposure to asbestos, the greater the chance of developing harmful health effects.

Disease symptoms may take many years to develop following exposure.

Asbestos-related conditions can be difficult to identify. Healthcare providers usually identify the possibility of asbestos exposure and related health conditions like lung disease by taking a thorough medical history. This includes looking at the person’s medical, work, cultural and environmental history.

After a doctor suspects an asbestos-related health condition, he or she can use a number of tools to help make the actual diagnosis. Some of these tools are physical examination, chest x-ray and pulmonary function tests. Your doctor may also refer you to a specialist who treats diseases caused by asbestos.

Three of the major health effects associated with asbestos exposure are:

  • lung cancer

  • mesothelioma, a rare form of cancer that is found in the thin lining of the lung, chest and the abdomen and heart

  • asbestosis, a serious progressive, long-term, non-cancer disease of the lungs

For more information on these and other health effects of asbestos exposure see the Agency for Toxic Substances and Disease Registry, the National Institute for Occupational Safety and Health and the National Cancer Institute.


We offer a wide range of asbestos air monitoring services:

Background Air Test. Provides data on respirable fibers in air prior to work with or near asbestos-containing materials.

Air Clearance & Certificate of Reoccupation. Inspection and air tests of enclosures required for the removal of certain asbestos-containing materials and the issue of a Certificate of Reoccupation.

Personal Asbestos Monitoring. Can be undertaken for employees working on or near asbestos-containing materials in order to provide information regarding suitable and safe working practices.


  • Asbestos minerals incorporated in building materials break down to very fine fibers when disturbed

  • These fibers can linger in the air for a considerable time. The fibers are so small that they penetrate very deep into the respiratory system; hence, they are referred to as respirable fibers.

  • Whilst other materials may generate respirable size fibers to some extent, this phenomenon is a particular characteristic of the asbestos minerals.

  • Airborne respirable fiber concentrations are determined by collecting airborne dust on cellulose nitrate filters and counting the fibers under phase contrast microscopy.



  • Reassurance asbestos air testing provides information on respirable fiber concentrations in air, and helps to define whether a work area is suitable for occupation.

  • Reassurance air sampling may follow some very minor work on an asbestos-containing material. Or it may be appropriate when damaged asbestos is found.



  • Background testing provides baseline information on respirable fibers in a building prior to asbestos work taking place.



  • In some instances employers are required to keep records of those who work with asbestos-containing materials.

  • Part of this record keeping can involve periodically measuring exposure levels of individual workers to respirable fibres.



  • A certificate of reoccupation is required on completion of licensed asbestos removal work.

  • Within the certificate of reoccupation there is an air clearance certificate which defines that the air quality has reached an acceptable standard, and normal activities can resume in the building.
