Bonded Asbestos vs. Friable Asbestos: What’s the Difference?

TLDR;

Here’s how to understand asbestos in its two most common forms.

• Bonded or “non-friable” asbestos is contained in concrete or other bonding materials, allowing minimal respirable particles to escape. This means it’s often seen as less risky to remove. 
• Friable (non-bonded) is in a form that’s easier to crumble and can be more easily breathed in. This puts those who handle it at increased risk of severe health complications.
• While it’s technically legal to remove small quantities of bonded asbestos yourself, it’s never recommended.

We’ve all heard of asbestos, and have at least some understanding of its dangers. While there’s no such thing as ‘safe’ asbestos, the risk profiles from different kinds of asbestos do differ. Here, we’ll talk through the classifications of ‘friable’ and ‘non-friable’, helping you understand what kinds of action you’ll need to take based on the kind of asbestos you suspect.

While this article will discuss the risk levels associated with each type of asbestos, it’s important to note that all asbestos can pose a risk, and an action plan should be made. Here we will discuss the two main types of asbestos and how to deal with them.

There’s no doubt that asbestos is a highly dangerous material, and each property’s asbestos profile will be different. Understanding what type you’re dealing with and its current condition is extremely important in understanding the immediate risk you’re facing. It might even help you find the right provider to help you through the process. And having an experienced provider who knows the best way forward at each stage is crucial. Safe removal practices keep you, your neighbours and the environment safe: you can’t compromise. 

From an average of 380 hazardous materials clearances a year, we’ve learnt a thing or two about asbestos in Australian homes. Here, we’ll share our expertise in asbestos identification, removal and clarify the best time to call in professional support. 

So, what are the different forms of asbestos you’ll encounter when taking on renovations and demolitions?

What is Bonded Asbestos?

Bonded (or non-friable) asbestos is asbestos fibres mixed into concrete or other similar bonding materials.

Less breakable as they’re contained within bonding materials.

While it’s true that bonded asbestos doesn’t generally pose a threat to human health if left undisturbed and undamaged, age alone is often enough to cause it to degrade, and accidents, natural disasters, fires, drilling, and vibrations can all cause non-friable to become friable (and a serious and immediate threat).

The removal method can also cause bonded asbestos to become friable, if care is not taken to avoid breaking the material.

Regulatory considerations:

While it is legal in a number of states to remove up to 10 square metres of bonded asbestos without a licensed contractor, it is highly discouraged by government, health, and environmental bodies. This is the case in Queensland. In such a case, you also need to use proper removal methods (protecting surfaces to prevent cross-contamination, vacuuming areas with a HEPA filter class “H” vacuum, double bagging and/or wrapping waste, etc) and extensive appropriate PPE such as a respirator, gloves, disposable coveralls and appropriate footwear. Items that are single use (gloves, coveralls, disposable respirators and/or air filters) must be disposed of as Asbestos contaminated material, alongside the asbestos, at a licensed facility and not placed into a general landfill. Items that are long-term use, like footwear and face mask need to undergo a thorough decontamination process.

For removing more than 10 square metres in Queensland, you’ll need a Class B licence.

There are serious penalties associated with improperly disposing of or removing all kinds of asbestos. Initial Services are fully certified with both Class A (friable) and Class B licenses, experienced personnel to execute Asbestos removal as per Industry Standards, and an EPA license to safely transport the Asbestos waste to the correct facilities: you can trust us to provide a safe, compliant service.

What is Friable Asbestos?

Friable asbestos is the name given to asbestos that’s not bonded inside other materials. This means it’s loose and easy to crumble, breaking down into respirable particles. 

This makes it extremely dangerous. Asbestos fibres, when breathed in, can cause life-altering, lethal health conditions. Where friable asbestos is concerned, extreme care needs to be taken at all stages.

It’s more common to find friable asbestos in commercial settings, especially in boiler and heating insulation, as well as in pipe lagging. It was also commonly used for its fire-resistant properties, as well as for its soundproofing capabilities,

In homes, you’re likely to find it as loose-fill insulation, around heating systems, and even in ceilings. 

SAFETY TIP: It’s also possible for non-friable (bonded) asbestos to become friable when damaged. Don’t make assumptions about safety based on what you can see – always consult a professional.

Only licensed removalists are allowed to remove asbestos in its friable form, regardless of quantity and conditions. An Occupational Hygienist must be engaged to execute air-monitoring and issue a clearance certificate once removal is completed, ensuring that the removal process was conducted as per Industry Standards and it is safe to re-occupy the area. Initial Services works closely with a wide range of Occupational Hygienists in Brisbane and can assist you in finding the right one for your job.

Risk Level

Friable asbestos has a higher risk profile than non-friable asbestos, mostly due to its ability to be broken down and inhaled. However, it’s far from risk-free. Remember: non-friable asbestos can become friable due to age, damage, or exposure to the elements. There is no such thing as ‘safe asbestos’. 

Why You Should Understand the Difference

Knowing the difference between these two materials ensures that you’re engaging in the right level of risk management. It’s important to understand that all asbestos can pose a serious danger to human and environmental health: just because your asbestos is bonded, it doesn’t mean you don’t need to take safety precautions or that you don’t need to speak to a professional. Bonded asbestos is commonly damaged or disturbed during renovations, when vibrations, drilling, and demolition works can cause the materials to become friable. Call in the experts whenever you’re considering demolition or renovation work: we can manage the risks and provide you with a path to a safer property. 

Bonded vs. Friable Asbestos: Key Differences

Why Professional Removal is Crucial

Safety takes many forms, and it’s the key motivation behind appropriate asbestos removal. Engaging in DIY asbestos removal puts you and the people in your property at risk, as well as neighbours and the environment.

The safety equipment required to safely remove asbestos is extensive: it’s likely beyond what you can find at your local hardware store! Working with a professional, you’re able to be sure that it’s done properly. While there is the possibility of DIY for small quantities of bonded asbestos, it’s rarely clear before you start the project if it’s possible or even appropriate.

Asbestos – being a fine and often invisible substance – can leave hidden traces that can be inhaled, often unknowingly. Professionals have the tools to contain this risk: the right equipment, the right protective gear, and the targeted use of dust suppression techniques. 

Environmental safety, too, should never be overlooked in this process: it’s just as much of a motivator for seeking professional help. Just as it’s dangerous to humans, asbestos is toxic to plants and marine life. For this reason, all asbestos-contaminated waste needs to be sent to a licensed landfill with appropriate documentation and safe, responsible handling. Know you’re putting your health – and the health of our natural environment – in safe hands – go with the professionals!
