Do I Need an Asbestos Air Test? Here’s What You Need to Know

An asbestos air test is a method used to determine whether asbestos fibres are present in the air. These fibres can be extremely hazardous when inhaled, leading to serious health issues such as mesothelioma, asbestosis and lung cancer.

Unlike bulk material sampling, where a physical sample of suspected asbestos-containing material is taken, an air test specifically checks the airborne environment. This is particularly important because inhalation is the primary risk associated with asbestos exposure.

There are two main types of air testing. Phase Contrast Microscopy, often used for occupational exposure monitoring, and Transmission Electron Microscopy, which is more detailed and sensitive, capable of detecting even very small asbestos fibres.

Certain situations greatly increase the likelihood that an air test is necessary. These include renovation or demolition projects. If your property was built before the late 1990s, when asbestos use was common, disturbing walls, ceilings or insulation can release fibres into the air. As well as this it may be worth having post-abatement verification as this is another important reason. This is after asbestos has been professionally removed, an air test is essential to confirm that the space is safe for reoccupation.

While asbestos fibres are microscopic and invisible to the naked eye, certain indicators suggest they may be present in the air. For example, visual clues can include exposed or damaged insulation, cracked pipe lagging, flaking ceiling panels or degraded textured coatings.

It is suggested that any recent work involving construction, drilling, sanding or renovation of suspect materials increases the risk of fibre release which could be another indicator that having a test could be beneficial to reduce any risk.

One of the biggest signs is persistent respiratory issues among people spending time in the building may suggest prolonged exposure to airborne irritants, including asbestos.

If a professional asbestos consultant visits your property, the process will typically involve the use of air monitoring equipment. Portable air pumps draw a set volume of air through a filter designed to capture airborne particles. The filters are then collected over a period of time, commonly several hours, to ensure enough air is analysed.

The samples are then sent to an accredited laboratory, where experts identify and count any asbestos fibres found. With this you will receive a detailed report with results, usually indicating the fibre concentration per cubic centimetre of air and whether the environment meets safety standards.

In the United Kingdom, asbestos is regulated under the Control of Asbestos Regulations 2012. This is where property owners, landlords and employers are legally required to assess and manage asbestos risks in non-domestic premises.

As said previously air testing may be required before or after renovation and demolition work on buildings that contain asbestos-containing materials.

However at a workplace the same rules apply and employers must protect workers from asbestos exposure. This includes appropriate testing and clearance procedures to ensure a safe working environment.

Overall failure to comply with these regulations can lead to serious legal and financial consequences, as well as potential health impacts on occupants and workers.

If your air test reveals the presence of asbestos fibres, it is essential to act quickly and responsibly. This means avoiding any additional activity that may release more fibres.

From there consult a licensed asbestos contractor like Smart Asbestos. Look out for contractors that are Health and Safety Executive licensed professionals as these should be the only service undertaking asbestos removal or containment.

After the removal a follow-up air test is recommended to ensure all airborne asbestos has been properly cleared. Also make sure to maintain documentation of any tests, work carried out and certifications. This is particularly important for landlords and owners of commercial properties.

Can I perform an asbestos air test myself?
No. Air testing requires specialised equipment and laboratory analysis by accredited professionals. DIY kits are not reliable and may not meet legal requirements.

Is asbestos always dangerous if present?
Not necessarily. If materials are intact and undisturbed, they may not pose an immediate risk. However, once damaged, asbestos becomes hazardous.

Is air testing required before renovations?
In many cases, yes. This is especially true if there is a likelihood of disturbing asbestos-containing materials. For commercial buildings, it is often a legal obligation.
