Ever wondered what raw asbestos looks like?

If you’ve never come across it before, you may wonder ‘What does asbestos look like?’

Asbestos can be difficult to identify as it’s often mixed in with other materials.

But there are some very common materials that are known to contain asbestos and some common places you will find it which we will show you in this article.

The one piece of advice though is that if you’re not sure if asbestos is present or not, then leave well alone and seek professional advice from an Asbestos Surveyor.

There are 3 main types of asbestos – Crocidolite (blue colour), Amosite (brown colour), and Chrysotile (white colour).

Below are photos of what these 3 main types of asbestos look like in their raw form.

Chrysotile was the most commonly used in residential and industrial buildings.

So what does asbestos look like in common materials?

Here are some descriptions of the common materials that contain asbestos and photos to show what they look like:-

Loose asbestos in ceiling or floor cavity

You will only ever actually see pure asbestos in loose fill material which will exist in ceilings or floor cavities. Loose fill asbestos was commonly used to insulate both industrial and domestic premises, so it can be found in between cavity walls, underneath floorboards and in loft spaces.

This asbestos material is a loose, fluffy insulation material which appears similar to candyfloss, which may look blue-grey or whitish in colour.

Loose fill is the most dangerous asbestos containing material and if it’s disturbed it can release large amounts of fibers into the air, where they can be breathed in and cause serious health problems such as mesothelioma.

Because of the high risk factor, anyone handling or removing loose asbestos MUST hold a license and be suitably trained to do so.

This type of asbestos is often applied to pipes and can be quite tricky to identify as it’s often covered in a protective coating (or painted) meaning you can’t look and see what’s lurking underneath. Although It has many different appearances, this asbestos material is mostly fibrous which flakes and powders very easily.

Recognised as being one of the most dangerous types of asbestos containing materials because it’s very easy for pipework or lagging to be disturbed, therefore releasing harmful asbestos fibers into the air that you breathe.

Sprayed coatings on ceilings, walls and beams/columns

This asbestos material will usually look white or grey in colour and will usually have a rough surface and may also have been painted over.

It was used for insulation on the underside of roofs and sometimes on the sides of buildings and warehouses.

Was also commonly used used as fire protection on steel and reinforced concrete beams/columns and on the underside of floors.

Again, it’s one of the most dangerous asbestos containing materials as even minor disturbance of sprayed coatings can release a large amount of asbestos fibers into the air.

Asbestos insulating board (AIB)

Asbestos Insulating board was a very versatile material, so was used in lots of different places for various purposes such as ceiling tiles, panels below windows, soffitts, partition walls, lift shaft linings and fireproofing panels in fire doors.

Although it’s not as dangerous as other materials, any prolonged exposure can still cause significant health risks.

Floortiles, textiles and composites

These old asbestos containing materials don’t look that different from modern materials, so it can be quite difficult to identify them.

Asbestos floor tiles were once very common, and so a lot of them will still be hidden underneath modern carpets and flooring.

As for textiles, you will find these in old fuse boxes, fire blankets and heat resistant gloves.

Examples of asbestos composites are toilet cisterns and seats, window sills, and bath panels.

Any work to remove these materials would be classed as non licensed asbestos removal as they are lower risk.

What does this asbestos look like?

Textured coatings

Asbestos textured coatings will have various finishes to them, so when you look at them you will usually see swirls or a stippled pattern.

You will find textured coatings on ceilings and walls, most commonly known as Artex.

They are white in colour and have a hard texture that is usually painted over, either in white or coloured paint.

Although there is a risk of asbestos exposure, textured coatings are classed as lower risk materials, so a license isn’t required to remove them, so long as the removal operative has been appropriately trained to do so (cat b non licensed)

What does this asbestos look like?

Asbestos cement products

Asbestos cement is cement mixed with mainly chrysotile (white) asbestos and is a hard, grey material to look at, which is then moulded and compressed to make asbestos cement products.

It can be found in many different places both inside and outside buildings such as asbestos cement roofs, asbestos wall cladding, asbestos downpipes and gutters, asbestos cement flues, asbestos cement and pitch fibre water and sewer pipes.

Work to remove asbestos cement products can be done by non licensed workers so long as they are trained.

What does this asbestos look like?

Roofing felt

Asbestos roofing felt can mainly be found on garage roofs, outbuildings etc.

Take a look at the photos below to see what asbestos roofing felt looks like.

Again, any work on roofing felt can be done by non licensed operatives, as long as they have the correct training.

What does this asbestos look like?

Rope seals and gaskets

Asbestos rope seals and gaskets are commonly found in gas and electric heating appliances. 

The photos below demonstrate what asbestos rope seals and gaskets look like.

Non licensed workers can carry out tasks on these materials if they have had the correct training.

Stay asbestos aware

Hopefully we have answered your question ‘What does asbestos look like?’ and you will now be able to identify common products and building materials that are likely to contain asbestos.

Remember that asbestos is very dangerous and still kills around 5000 workers each year, which is more than the number of people killed on the roads.

Figures show that around 20 tradesman die each week as a result of past exposure to asbestos.

So make sure you are asbestos aware. Take care to never unnecessarily expose yourself or others to asbestos.

Only those who have completed the correct training should handle asbestos containing materials.

For more information and guidance on what to look out for when it comes to asbestos and how it can affect your health, please visit the HSE website.

Duty holders and employers have a legal responsibility to manage asbestos in their properties, carrying out an asbestos survey in their building so as not to put employees at risk.

So make sure you contact our Armco office to arrange asbestos testing or an asbestos survey, before it’s too late!
