Rationale
Depending on how and where asbestos was applied, it might not pose any risk to most users of the building. If the fibers cannot become dislodged, they cannot be inhaled, and thus the asbestos poses no risk.
However, some methods of applying asbestos, particularly flocking, allow asbestos fibers to gradually drop off into the air. Asbestos poses hazards to maintenance personnel who have to drill holes in walls for installation of cables or pipes.
Even if the workers are protected, such maintenance operation may release fibers into the air, which may be inhaled by others. Interventions in areas where asbestos is present often have to follow stringent procedures.
When asbestos fibers can easily be made into airborne dust, the material is known as friable. For example, a popcorn ceiling is extremely friable, whereas asbestos floor tile is considered non-friable.
Different countries have different regulations and methods of enforcement, when it comes to asbestos removal. It is extremely important to remember that prior to any asbestos removal procedures taking place; the client has a duty of care and must verify that the specialist removal contractor can provide the following: proof of licence if licencing is required within the jurisdiction; proof of specific asbestos public and employer liability insurance; proof of worker training to include supervisor and contract manager training within 12 months; proof of worker fit-testing and medical surveillance, within 12 months; proof of specialist equipment testing within 6 months - DOP and PAT within the EU. Optionally the specialist contractor should be able to provide accreditation from ARCA or other such trade organization.
