Asbestos clearance inspection by Safe Environments’ asbestos consultants provide assurance that an area is safe to occupy after asbestos removal has taken place. Most buildings in NSW built prior to 1990 will generally comprise some degree of asbestos and require an asbestos inspection to provide certification where asbestos is located.
To determine if asbestos is present in a material to a building, asbestos testing takes place by a consultant taking a sample during the asbestos inspection and then analysing the material in a laboratory.
The results of the asbestos inspection are provided within an asbestos register which includes the location of the asbestos containing material and a risk assessment to assess potential health risks. In general asbestos does not pose a significant health risk if maintained in a good condition and left undisturbed.
However, during demolition or refurbishment asbestos may be required to be removed. In many situations the majority of asbestos is found within fibre cement sheet. In a good condition asbestos cement sheet is in a bonded form which means that its cant be pulverised or crushed by hand to a power. When removing bonded asbestos building materials, the contractor must have a NSW asbestos license and notify NSW WorkCover 7 days prior to the asbestos removal
During the removal process an inspection of respirable asbestos fibres in the air (control monitoring) will assist in assessing potential asbestos exposure outside the work area and also provide an indication of the effectiveness of the control measures. At the completion of the asbestos removal an asbestos clearance inspection is undertaken by the asbestos consultant to provide certification that all visible traces of the asbestos material have been removed.
An additional asbestos clearance inspection is generally carried out to provide certification that the amount of respirable asbestos fibres in the air is to a safe level. An area is considered to be safe when the asbestos clearance inspection measures the level of airborne asbestos fibres to be below 0.01 fibres/mL. The results of the asbestos clearance inspection and asbestos air monitoring must be included within the asbestos register to show that the removal has been conducted in a safe manner.
