If you work in construction or any other industry where you may disturb or be exposed to asbestos-containing materials (ACM's), you need to have asbestos awareness training. This minimum level of asbestos training is required by law under the Control of Asbestos Regulations (CAR).

If you have had, or are about to refresh, your asbestos awareness, you should be able to answer these 10 asbestos awareness questions. Or, if you have never done the course before, this information should give you a good head start. Don't worry if you are not sure about the answers - we explain them below to help prepare you for your asbestos awareness course.

1. In which year were all asbestos products banned in the UK?

Answer: 1999.

Blue (crocidolite) asbestos and brown (amosite) asbestos were banned first in 1985. But it wasn't until white (chrysotile) asbestos was banned in 1999 that all asbestos products got banned in the UK.

The Asbestos (Prohibitions) (Amendment) Regulations 1999 came into force on the 24th of November 1999 and banned the importation and supply of all types of asbestos.

2. What are the three common types of asbestos?

Answer: Chrysotile, Amosite, Crocidolite.

Also known as white, brown and blue asbestos. Chrysotile, Amosite, and Crocidolite are the three common types of asbestos used in UK construction.

3. What is a disease caused by asbestos?

Answer: Mesothelioma.

Mesothelioma is one of the biggest asbestos-related diseases, killing around 2,500 people in the UK each year. But asbestos is deadly and can cause a variety of different diseases. You could also choose asbestosis, lung cancer, pleural plaques or stomach and larynx cancer as your answer.

4. When does an asbestos-containing material become dangerous?

Answer: When it is disturbed.

If asbestos is left alone, it is low risk. You are not in immediate danger from asbestos materials if they are in good condition and intact. However, if asbestos-containing materials are disturbed, through sanding, drilling, cutting etc. or if they are in poor condition, then deadly asbestos fibres are released.

5. What is the main route of entry for asbestos fibres?

Answer: Inhalation.

The main risk from asbestos fibres is through inhalation. It is the most common way that asbestos enters the human body. Asbestos fibres are so tiny they can remain suspended in the air for days, and when breathed in, they can become lodged in the lining of the lungs.

6. What type of asbestos survey is needed for construction work?

Answer: Refurbishment and demolition asbestos survey.

There are two types of asbestos survey, a management asbestos survey, and a refurbishment and demolition asbestos survey.

For building work, you need the refurbishment and demolition asbestos survey, which is the more intrusive type of asbestos survey. The building gets inspected with samples taken and tested to identify any asbestos materials present in the areas you are working on and disturbing as part of the project.

7. Why are smokers at increased risk from asbestos?

Answer: Because they have reduced lung function.

Smoking damages the tiny hairs in the throat and lungs and desensitises the lungs from smoke and particles. The immune system reduces the white blood cells sent to clean up the lungs.

Because of this reduced function, smokers are at a higher risk of asbestos-related diseases. When smokers get exposed to asbestos fibres, their lungs are less likely to fight off asbestos fibres.

8. Which buildings might contain asbestos?

Answer: Any built before 2000.

Because asbestos materials were used so heavily from the late 1800s to the ban in 1999, any building built before 2000 is likely to contain asbestos unless it has previously been removed.

Even building older than the late 1800s may have been refurbished during the period asbestos was in use and had asbestos products and materials installed then.

Unless you have an asbestos survey or removal records, always assume any building constructed before 2000 contains asbestos.

9. Why might you not know if you have disturbed asbestos?

Answer: Because asbestos-related diseases take years to develop.

You don't die from asbestos exposure immediately. Asbestos-related diseases can develop over several years and often over decades. And it's hard to tell if a material contains asbestos without a survey. You can't know if a material contains asbestos just by looking at it.

With no immediate warning signs, make sure you check what type of materials you are working on.

10. How many people die in the UK each year from asbestos exposure?

Answer: Over 5000.

Currently, it is estimated that over 5000 people die each year from past asbestos exposure.

Around 2500 people die from mesothelioma each year. Around the same number of people die from asbestos-related lung cancer, and approximately 450 people die from asbestosis each year.
