What is the typical asbestos content of Asbestos Insulating Board (AIB)?

Asbestos Insulating Board (AIB) typically contains 25-40% asbestos. This relatively high asbestos content, combined with its friable nature, makes AIB one of the higher-risk asbestos-containing materials commonly found in buildings.

Which of the following best describes the physical characteristics of Asbestos Insulating Board (AIB)?

AIB is characterised by being soft, friable (easily crumbled) and of relatively low density. It can often be identified by its soft texture compared to asbestos cement, and it releases fibres more readily when disturbed.

Transparent and flexible like plastic sheeting

Soft, friable and of relatively low density

Metallic in appearance with a shiny surface

What is the typical asbestos content of asbestos cement (AC) products?

Asbestos cement typically contains 10-15% asbestos, with the remainder being Portland cement. The lower asbestos content and the binding effect of the cement matrix mean that fibres are less readily released compared to AIB, provided the material remains in good condition.

Sample questions

01What is the typical asbestos content of Asbestos Insulating Board (AIB)?
- A.25-40%
- B.1-5%
- C.10-15%
- D.50-70%
Why: Asbestos Insulating Board (AIB) typically contains 25-40% asbestos. This relatively high asbestos content, combined with its friable nature, makes AIB one of the higher-risk asbestos-containing materials commonly found in buildings.
02Which of the following best describes the physical characteristics of Asbestos Insulating Board (AIB)?
- A.Hard, dense and grey in colour
- B.Transparent and flexible like plastic sheeting
- C.Soft, friable and of relatively low density

Why: Asbestos cement typically contains 10-15% asbestos, with the remainder being Portland cement. The lower asbestos content and the binding effect of the cement matrix mean that fibres are less readily released compared to AIB, provided the material remains in good condition.

FAQ

Is the Identification & Surveys mock exam free?

Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.

Can I retake the mock exam?

Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.

Does this count towards the real qualification?

No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
