UKATA Asbestos-Containing Materials (ACMs) in Buildings 1 — Questions and Answers
Question 1: Which building application commonly used sprayed asbestos coatings in pre-2000 UK buildings?
- External roof cladding
- Decorative plasterwork on walls
- Fire protection on structural steelwork (Correct answer)
- Insulation beneath timber floors
Correct 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.
Question 2: In which year was the use of all forms of asbestos finally banned in the UK?
- 1985
- 1992
- 1999 (Correct answer)
- 2006
Correct 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.
Question 3: Asbestos insulating board (AIB) is most commonly found in which building application?
- Underground drainage pipes
- Ceiling tiles and fire-resistant partition boards (Correct answer)
- External paving slabs
- Decorative ceramic floor tiles
Correct 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.
Question 4: Why are asbestos cement (AC) products generally considered lower risk than asbestos insulating board (AIB)?
- They contain no more than 1% asbestos by weight
- The asbestos fibres are firmly bound within the cement matrix (Correct answer)
- They are always found outdoors where air disperses fibres
- They were manufactured using only white asbestos
Correct 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.
Question 5: Which of the following is a typical location where asbestos textured coatings (such as Artex) were applied?
- External brick walls
- Domestic ceilings and interior walls (Correct answer)
- Garage forecourt surfaces
- Swimming pool surrounds
Correct 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.
Question 6: Which type of asbestos-containing material is classified as 'friable' and poses the greatest risk of fibre release?
- Asbestos cement corrugated roof sheets
- Vinyl floor tiles containing asbestos
- Sprayed asbestos thermal and fire coatings (Correct answer)
- Asbestos rope seals in boiler doors
Correct 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.
Question 7: Which of the following materials found in older UK buildings does NOT typically contain asbestos?
- Boiler flue pipes
- Textured decorative ceiling coatings
- Double-glazed sealed window units (Correct answer)
- Thermal lagging on heating pipes
Correct 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.
