Asbestos refers to a group of naturally occurring silicate minerals, which consist of microscopic fibers that can easily break and become airborne. When inhaled, these fibers can cause serious health problems to individuals, most notably lung cancer, mesothelioma, and asbestosis - a chronic lung condition characterized by scarring and inflammation.

The use of asbestos was popular in the UK, particularly between the 1950s and 1980s, as it was considered an excellent insulation and fire-resistant material. Despite its known dangers, millions of buildings erected during this period contain asbestos materials.

This, therefore, means that many buildings in the Westborough area could be affected by asbestos. Asbestos can be found in different parts of buildings such as pipe lagging, textured coatings, asbestos concrete, insulation of electrical apparatus, among others.
