What is asbestos?
Asbestos is a naturally occurring fibrous material and has been used for about 150 years on a large scale. It is versatile, plentiful and ideal as a fire-proofing and insulation material. But it can be deadly!
The three main types of asbestos that have been used commercially are:
-Crocidolite (blue)
-Amosite (brown)
-Chrysotile (white)
Basic facts:
1000 people who worked in these trades die from cancer every year as a result of breathing asbestos fibres.
There’s still a lot of old asbestos in buildings
Any building built or refurbished before 2000 is still likely to contain asbestos.
Asbestos is responsible for an estimated 4000 deaths a year
Why is it dangerous?
If you inhale asbestos fibres (which are long and thin) they can become lodged in the tissue of your chest and your body’s natural defences may not be able to easily break them down. This can lead to lung diseases (mainly cancers), particularly if you are repeatedly exposed to fibres over a number of years.
Effects on health:
- Exposure to asbestos can cause three main diseases:
- Asbestosis: irreversible scarring of the lungs;
- Lung cancer: increased incidence, particularly if you smoke;
- Mesothelioma: cancer of the lining of the lungs or stomach.
Note: These diseases have no cure – mesothelioma and lung cancer are fatal diseases.
Typically, there can be a 15–60 years gap between first exposure and diagnosis.
Who’s at risk?
- Electricians
- Plumbers
- Date cabling operatives
- Joiners
- Heating & ventilation engineers
- Construction workers
- Other similar occupations
Where is it found?
- Asbestos cement products
- Textured pain coatings
- Floors tiles, textiles and composites
- Sprayed coatings on ceilings, walls and beams
- Asbestos insulation boards
- Lagging
- Fire blankets
- Window sills
- Panelling
- Loose asbestos in ceiling/floor cavity
What to do if you discover asbestos at work:
- Stop work
- Inform supervisor/contract manager
- Inform client
- Do not restart until told to do so by contracts manager or supervisor
If you think you may be working with asbestos:
- Liaise with the client
- Request a copy of a recent asbestos survey
- Check the asbestos survey against the work that you will be doing
- Constant vigilance
What to do if you need to work with it:
- Use hand tools - not power tools: they create too much dust
- Keep materials damp - not too wet
- Wear a properly fitted, suitable mask (eg. disposable FFP3 type). An ordinary dust mask will not be effective
- Don't smoke, eat or drink in the work area
- Double-bag asbestos waste and label the bags clearly and correctly
- Clean up as you go - use a special (Class H) vacuum cleaner, don’t sweep up asbestos.
- After work, wipe down your overalls with a damp rag or wear disposable overalls
- Always remove overalls before removing your mask
- Don't take overalls home to wash
- Wear boots without laces or use disposable boot covers
- Put disposable clothing items in asbestos waste bags and dispose of them properly- don’t reuse disposable clothing.
- Don't carry asbestos into your car or home – even accidentally!
