Central Coast Asbestos Removal: Home Asbestos Testing Guide
The extreme consequences for health after inhaling asbestos fibres mean Central Coast asbestos removal is often essential for the continued health and safety of local families.
Asbestos testing may be particularly relevant for homeowners in older homes on the Central Coast.
This important guide explains the risks to you and your family if your home contains asbestos. Find out the step-by-step process used to identify any risks and remove any asbestos hazards from your property.
Why Asbestos Remains a Critical Concern for Australian Homeowners
Asbestos was widely used across NSW for its heat resistance, durability, and insulating properties until the use of asbestos in construction materials was banned in Australia in 2003. Of course, many homes built or renovated before this still contain asbestos-containing materials (ACMs).
The Central Coast region, in particular, will have many buildings containing asbestos, due to local building booms in the 1970s-1990s.
Generally, asbestos is safe when left undisturbed, but it poses a serious health risk if it deteriorates or becomes disturbed during renovations or demolition.
What Is Asbestos and Where Does It Hide?
Asbestos material is a naturally occurring mineral fibre and was widely used in construction until the severity of its health hazards became apparent.
There is a common misconception about the appearance of asbestos. In reality, it is often combined with other construction materials.
Common Locations in Australian Homes
The age of your home is an initial indicator of the risk of asbestos being present. It is not always obviously visible.
Some areas where asbestos is commonly found include:
- The roof
In materials such as cement roof tiles, shingles, and eaves. - Walls and ceilings
Fibro sheeting, textured coatings, and insulation may all be ACMs. - Floors
In vinyl tiles, backing material, and adhesives. - External areas
Like fences, garden sheds and weatherboards. - Pipes and electrical
Asbestos was often used for insulation wrapping and is found in older electrical meter boards.
Types of Asbestos Found in Australian Buildings
There are six different types of asbestos, with three of these typically used in Australian buildings:
- Chrysotile (white asbestos)
The most common type is normally found in roofing and walls. - Amosite (brown asbestos)
Mainly in cement sheets and pipe insulation - Crocidolite (blue asbestos)
The most hazardous type, mainly used in spray coatings and cement products - Some of the less common types are sometimes found as contaminants
Understanding the Health Risks of Asbestos Exposure
When asbestos fibres are disturbed and become airborne, they can be inhaled by anyone unlucky enough to be near the source. The resulting effects may not appear for decades. There is no safe level of exposure.
Asbestos-Related Diseases
Some diseases caused by exposure to asbestos:
- Asbestosis
This is progressive lung scarring that impairs breathing capacity. - Lung cancer
Can develop 20-40 years after exposure, with a higher risk for smokers. There will certainly be people today, most often construction workers, who will develop asbestos-related lung cancer. - Mesothelioma
Another aggressive cancer affecting the lung lining. It is often fatal.
How Asbestos Becomes Dangerous
Non-friable or bonded asbestos poses minimal immediate risk if left undisturbed.
Friable asbestos is soft and easily crumbles, potentially releasing fibres into the air.
Some of the ways stable, non-friable asbestos can become friable and, therefore, hazardous are:
- Deterioration
Caused by weathering, water damage, or simply age, releasing fibres. - Renovation activities
Drilling, cutting, sanding, or breaking materials containing bonded asbestos. - Natural disasters and accidents that damage buildings and structures.
When Should You Test for Asbestos?
If you have the slightest suspicion that friable asbestos may be present in your property, contact a dependable asbestos testing, removal and disposal contractor immediately!
Normally, situations where you should arrange for an asbestos check include:
- Before renovation, demolition, or construction work.
- If you are considering buying a pre-2003 Central Coast property.
- When you notice that construction materials have deteriorated or show signs of wear or damage.
- Before selling an older property for transparency and to reassure potential buyers.
- In the event of unexplained health symptoms, particularly suspected lung diseases or breathing problems, arising in older properties.
The Professional Asbestos Testing Process
Because of the extreme health risks, trying to identify asbestos yourself is dangerous for you and others, and the results may be unreliable.
Professional contractors have an established and proven step-by-step assessment process.
Initial Property Assessment
The first step is a site inspection by an experienced asbestos assessor. This involves:
- A review of the property’s age, construction type, and any renovations, particularly if they happened before 2003.
- A visual inspection of accessible internal and external areas.
- The location, appearance and likely age of suspect materials are logged. Photographs are taken of every item.
Sample Collection Procedures
In this stage of the process, samples are collected as follows:
- A professional, trained assessor will always wear full personal protective equipment (PPE) inside any premises suspected of having ACMs.
- Small samples are collected using wetted techniques to minimise the risk of fibre release.
- Normally, a sample is from every location noted during the site assessment.
- The samples are immediately sealed in approved, labelled containers.
Laboratory Analysis Standards
The samples must be delivered to a National Association of Testing Authorities (NATA) laboratory. In Australia, only a NATA-accredited testing facility can provide legally valid results.
- Testing confirms the presence of asbestos and identifies the type and concentration levels.
- Results are typically available within 3-7 business days.
- The laboratory issues certificates detailing its findings and the identification of the material.
What Happens After Asbestos Is Identified?
A decision will be made on whether to remove the asbestos from the property. If so, asbestos removal and disposal are subject to strict regulatory requirements in NSW.
Asbestos Management Options
There are certain circumstances where asbestos can remain in the building:
- Undamaged, stable non-friable asbestos can often remain if properly managed and monitored.
- It may require professional sealing to prevent future fibre release.
- Regular inspections should be scheduled to confirm the ongoing safe condition of the asbestos.
- Locations and details are documented in an asbestos register for future owners or tradespeople.
Professional Removal Requirements
Homeowners can legally remove small quantities of non-friable asbestos. Frankly, this could be very dangerous. If the stable asbestos is damaged, it can become friable and potentially life-threatening!
Only a licensed asbestos removalist may remove any friable asbestos and quantities over 10 square metres and safely dispose of asbestos waste. Here’s what you can expect:
- The removal will follow strict SafeWork NSW protocols and regulations.
- Material removed will be sealed using containment, air monitoring, and decontamination procedures.
- Material removed is securely transported to approved and registered disposal facilities.
- Clearance certificates are issued upon completion of the removal.
