Asbestos-Containing Materials (ACMs) in Buildings Flashcards

Which building application commonly used sprayed asbestos coatings in pre-2000 UK buildings?

Answer: Fire protection on structural steelwork

Sprayed asbestos (also called limpet) was widely applied to structural steelwork beams and columns as fire protection in commercial and industrial buildings.

In which year was the use of all forms of asbestos finally banned in the UK?

Answer: 1999

The Asbestos (Prohibitions) (Amendment) Regulations 1999 banned the use, supply, and importation of all remaining asbestos types in the UK from November 1999.

Asbestos insulating board (AIB) is most commonly found in which building application?

Answer: Ceiling tiles and fire-resistant partition boards

AIB was widely used in the UK for ceiling tiles, partition boards, door linings, and fire-resistant panels, particularly in buildings constructed between the 1950s and 1980s.

Why are asbestos cement (AC) products generally considered lower risk than asbestos insulating board (AIB)?

Answer: The asbestos fibres are firmly bound within the cement matrix

In asbestos cement, fibres are encapsulated within the hardened cement matrix, meaning they are not readily released unless the material is broken, cut, or severely weathered.

Which of the following is a typical location where asbestos textured coatings (such as Artex) were applied?

Answer: Domestic ceilings and interior walls

Artex and similar textured coatings containing chrysotile asbestos were extensively applied to domestic ceilings and interior walls for decorative finishes from the 1950s to the late 1980s.

Which type of asbestos-containing material is classified as 'friable' and poses the greatest risk of fibre release?

Answer: Sprayed asbestos thermal and fire coatings

Sprayed asbestos coatings are highly friable, meaning they can be crumbled to dust by hand pressure alone, releasing large quantities of asbestos fibres into the air very easily.

Which of the following materials found in older UK buildings does NOT typically contain asbestos?

Answer: Double-glazed sealed window units

Double-glazed sealed window units are a modern product and do not contain asbestos; boiler flues, textured coatings, and pipe lagging are all well-known ACMs in pre-2000 buildings.
