Asbestos is a naturally occurring mineral fibre that takes millions of year to form. It was widely used in the UK construction industry between the 1950s and 1990s. It was routinely added to products such as cement, thermo plastics, insulation products and insulating board, so most houses and commercial properties built during this period are highly likely to contain some asbestos within the structure.

Asbestos was used because it was relatively low cost and had many beneficial properties, including:

  • Does not burn until 1000 degrees centigrade
  • Does not conduct heat
  • Not affected by chemicals or electricity
  • Has a very high tensile strength

Materials containing asbestos are generally safe if they are in good condition. However, if they are damaged or broken, they can release fibres and dust into the air. These fibres, can damage lungs and lead to serious diseases such as lung cancer and mesothelioma.

With so many products having been produced and so many non-asbestos products which may look similar it can be very difficult for the untrained eye to identify asbestos. Our surveyors have an expert knowledge of the uses of asbestos and the types of products it may be contained within, but even then, samples are taken in order to confirm if asbestos is present and identify the exact type of asbestos.

Materials containing asbestos are generally safe if they are in good condition. However, if they are damaged or broken they can release fibres and dust into the air. These fibres can then harm your lungs and lead to serious diseases such as lung cancer and mesothelioma.

Certain types are flexible

Asbestos was used in over 3000 products and materials – you’d be surprised what everyday items it can turn up in. Here are some examples:

  • Asbestos cement products include, garage roofs, sheds, guttering, down-pipes, wall panels, bath panels, flue pipes, water tanks, patio tiles, roofing tiles and soffit boards.
  • Asbestos insulation board has been used for things like fire protection panels on cupboards and doors, ceiling tiles, partition walls and soffit boards.
  • Asbestos lagging was used to insulate pipes and boilers. However, it is less common in homes, especially those built after the mid-1970s, but we still come across it fairly frequently in commercial premises.
  • Asbestos sprayed coatings were used to protect structural steel from fire, amongst other uses.
  • Other asbestos products include some decorative coatings (most commonly known as Artex), plastic floor tiles, paper-backed floor lino and even toilet cisterns.

Leave the affected areas alone and contact us. We can give you some further advice and we’ll only recommend a survey if we feel it is absolutely necessary. Avoid sanding, sawing, drilling or disturbing these materials. Do not attempt to remove asbestos lagging, spray coatings or large areas of insulation. These can only be safely removed by a licensed contractor.

There are two types of asbestos surveys, as set out in HSG264 ‘Asbestos: The survey guide’, which replaced MDHS100 in January 2010. These are ‘management surveys’ and ‘refurbishment or demolition surveys’.

Management asbestos surveys help you comply with the law. They identify asbestos in all accessible areas, provide risk assessments on all asbestos-containing materials identified and make recommendations where problems are identified.

Refurbishment or demolition asbestos surveys are much more intrusive and use destructive methods in order to access areas which would normally be classed as inaccessible within a management survey. You would only require this type of survey if you were carrying out major refurbishment or demolition. The aim of these surveys is to locate all asbestos within all areas of the building so that the correct measures can be taken prior to refurbishment or demolition.

Prior to carrying out any works involving asbestos, it is essential you talk to an expert. We don’t charge for advice over the phone and a simple conversation in most cases can ascertain whether or not you are permitted to deal with the type of asbestos you have, or whether you would be breaking the law if you did so.

If we detect that there is a problem, we can arrange for the damage to be repaired or for the asbestos to be removed and disposed of safely. We will keep you fully informed and give you a number of possible options. Core always aims to provide practical, financially viable solutions and offer a full project management facility.

No. Generally, it is better to leave asbestos-containing materials in place, especially if they are in good condition, so as to avoid unnecessary disturbance of asbestos fibres. In this situation, strategies to seal, encapsulate, repair, enclose and protect are preferred. A risk assessment will be carried out on all products, which will help in deciding the best course of action.

Regulations were first introduced in 2002 and were the Control of Asbestos at Work Regulations (CAWR2002) but these were superseded in 2006 by the Control of Asbestos Regulations (CAR2006) and most recently the Control of Asbestos Regulations 2012 (CAR2012).

The most important points to note are Regulation 4 and Regulation 10. In summary Regulation 4 places a duty to manage asbestos on the duty holder, this may be the owner of the property, landlord or the manager of the business within the premises. The regulation covers non-domestic premises and the communal areas within domestic dwellings, blocks of flats for instance. Note that it is a duty to manage, not a duty to survey! It just so happens that often you will need to have a survey carried out in order to be able to manage asbestos.

But the survey is only the first step to managing asbestos, by having a survey carried out and then allowing it to gather dust on the shelf you are not complying with the regulations.

Regulation 10 relates to training. Those most likely to be exposed to asbestos nowadays are people within the trades, electricians, plumbers, etc., those who may be disturbing asbestos on a regular basis, often without knowing they are doing so. By implementing training, tradespeople, contractors and staff are more likely to be able to identify possible asbestos materials and therefore ensure safe working practices. Training saves lives.

Also note that the Construction Design Management Regulations (CDM2007) may also require an asbestos survey to be carried out, specifically where major refurbishment or demolition is taking place.

The six types of asbestos fall into two groups:

  • Amphiboles:
    • Crocidolite (blue asbestos)
    • Amosite (brown asbestos)
    • Anthophyllite, Actinolite & Tremolite
  • Serpentine:
    • Chrysotile (white asbestos)

Amphibole asbestos have needle-like fibres that break down into much smaller fibres than Serpentine asbestos, making them more aerodynamic and penetrative, and therefore a higher health risk through either inhalation or becoming embedded in the skin.

Asbestos-related diseases include Mesothelioma, an increasingly common cancer of the lung and abdomen; Asbestosis, an irreversible and progressive lung condition; pleural thickening; and asbestos warts.  However, asbestos-containing materials only become dangerous when they are damaged or in poor condition and handled without due care. Identification, risk assessment and management of asbestos are therefore critical in ensuring building occupiers are not exposed to asbestos fibres.

With so many asbestos products having been produced, and many non-asbestos items looking very similar, it can be extremely difficult to identify asbestos products. Core’s team of asbestos specialists have been trained in identifying potential asbestos containing materials and we can assist in asbestos management and removal of asbestos-containing materials.

Asbestos has been used in over 3000 asbestos products and materials; surprisingly many of them are everyday items. The diagram below shows a variety of examples including:

  • Asbestos cement products including garage roofs, sheds, guttering, down-pipes, wall panels, bath panels, flue pipes, water tanks, patio tiles, roofing tiles, soffit boards.
  • Asbestos sheets used as insulating boards for fire protection on cupboards and doors, ceiling tiles, partition walls etc.
  • Asbestos lagging was used to insulate pipes and boilers, as well as underlay.
  • Other products include decorative coatings (i.e. ‘Artex’ finishes), floor tiles, floor lino and toilet cisterns.
