What do you know about asbestos?
• Outline four things you know
about asbestos.
![Page 3: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/3.jpg)
What could be asbestos here?
![Page 4: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/4.jpg)
What is asbestos?
• Asbestos is a naturally
occurring mineral which has
been in use for over 2,000
years.
![Page 5: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/5.jpg)
What is asbestos?
• There are three common
types of asbestos
• Chrysotile (‘white
asbestos’)
• Amosite (‘brown asbestos’)
• Crocidolite (‘blue asbestos’)
![Page 6: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/6.jpg)
Useful properties
• Fireproofing
• Insulation
• Weather resistance
![Page 7: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/7.jpg)
Typical applications
• Gaskets
• Fire blankets
• Ropes
• Asbestos Insulation board (AIB)
• Pipes & tanks
• Floor tiles
• Textured coatings (‘Artex’)
• Resin composite
![Page 8: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/8.jpg)
Asbestos legislation
• The Control of Asbestos at Work
Regulations 2002 requires that
University of Brighton manages
asbestos and prevents exposure to
persons
![Page 9: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/9.jpg)
Why worry about asbestos?
• Asbestos is only a problem
when it is disturbed or in poor
condition
• Greatest risk to maintenance
operatives is accidental
disturbance
![Page 10: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/10.jpg)
Why worry about asbestos?
• It can be hazardous when
breathed in
• When an unplanned
disturbance occurs microscopic
fibres are release into the air
• These fibres lodge in the lungs
and they cannot be expelled
![Page 11: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/11.jpg)
Why worry about asbestos?
• Any fibres lodged in lung
tissue can lead to
• asbestosis
• lung cancer
• mesothelioma
![Page 12: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/12.jpg)
Asbestosis
• Usually applies to heavy and
regular exposure
• It is incurable
• Restricts the lung function
• Increased risk of lung cancer
![Page 13: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/13.jpg)
Lung Cancer
• Smoking multiplies risk
• A smoker is 15 times more likely to
suffer from lung cancer
• A smoking asbestos worker is 75
times more likely to suffer with
lung cancer
![Page 14: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/14.jpg)
Mesothelioma
• Caused by all kinds of particle
exposure but particularly blue
• Is a form of cancer
• Exposure level unknown but is low
![Page 15: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/15.jpg)
Mesothelioma
• Is incurable and painful
• Can develop anytime between 20-
40 years from the exposure
• Deaths from it are estimated to
peak at 2500 every year between
the years 2011 and 2015
![Page 16: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/16.jpg)
Mesothelioma symptoms
• Chest pain and pain in the lower back
• Difficulty breathing
• Coughing
• Weight loss
• Fever
• Muscle weakness and sensory loss
• Swelling of the face and arms
• Hoarseness
• Coughing up blood
![Page 17: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/17.jpg)
Why is the exposure to asbestos still a problem in buildings?• From the 1950s until the 1980s
asbestos was used extensively in the
UK
• This use continued until 1999
• Thousands of tonnes of asbestos still
in buildings
• You are likely to find it in any building
constructed before the year 2000
![Page 18: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/18.jpg)

Discovering suspect materials
• If it is not in the asbestos register, and you
feel it may be asbestos - assume it is!
• Ceiling tiles were removed at this location
because they were asbestos, this revealed
asbestos shown in photo
![Page 31: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/31.jpg)
Suspect material awareness
• Be careful, as other
asbestos containing
materials are not obvious
![Page 32: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/32.jpg)

Asbestos check procedure before starting work
• When you receive any work requests,
you must consider whether the work
involved may disturb any of the
adjoining building materials, which
could contain asbestos.
• If you feel there is any risk then you
must check the asbestos register
prior to commencing work.
![Page 37: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/37.jpg)
Asbestos check procedure before starting work
• University of Brighton
maintenance operatives are not
permitted to work with asbestos.
• Only contractors licensed by
Health and Safety Executive are
permitted to undertake work with
asbestos, under controlled
conditions.
![Page 38: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/38.jpg)
Asbestos check procedure before starting work
• DO NOT ASSUME that asbestos is not
present.
• If you have concerns – Ask STO /
Asbestos Co-ordinator / Maintenance
Manager
![Page 39: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/39.jpg)
Emergency procedure
• If anyone suspects that asbestos has been
disturbed then the following steps should be
taken IMMEDIATELY:
• Stop work
• Evacuate the area, without causing alarm
• Secure the area
• Contact STO and/or Asbestos Co-
ordinator
• Do not re-enter the work area
![Page 40: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/40.jpg)
How to find the asbestos register
• The asbestos register is found on the
University intranet at
http://staffcentral.brighton.ac.uk/asbestos/
![Page 41: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/41.jpg)
Asbestos Co-ordinator
• Andrew Knight is the University
Asbestos Co-ordinator
• Contact for general advice on
• using the asbestos register
• dealing with suspicious materials
• reporting incidents
![Page 42: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/42.jpg)
How to use the asbestos register
• Practical
demonstration +
handout
![Page 43: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/43.jpg)
What could be asbestos here?
![Page 44: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/44.jpg)
Substitution of asbestos materials
• When you have replaced a section
only of AIB with a non-asbestos
equivalent, could this item be
useful in obtaining future access?
i.e. a single tile in an asbestos
ceiling?
• See example – this section of
ceiling was replaced to enable safe
access to the fitting. How can we
identify the non-asbestos material
when the ceiling is painted?
![Page 45: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/45.jpg)
Procedure to label materials that are not asbestos
• There are two instances where we may
wish to label non-asbestos material
• 1 – Where only a small part of a
component is replaced, as previous
slide; and
• 2 – Where an item is clearly suspicious,
but has been tested and confirmed to be
non-asbestos, but may raise further
concerns in the future.
![Page 46: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/46.jpg)
Procedure to label materials that are not asbestos
• Green discs are available from
your STO, these are used to
label materials that are non-
asbestos. These should be
screw fixed in place and
adhesive labels should be
avoided.
![Page 47: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/47.jpg)
Substitute material selection
• Look carefully to identify what the
original material was put in to do
• The non asbestos substitute MUST
be able to do the same thing
• Extreme care must be taken to
ensure that this is done
i.e. replacing asbestos fire stopping
with a non-fire resistant material
![Page 48: Asbestos awareness for Craftsman Presented by Bob Miller & Andrew Knight](https://reader036.vdocuments.us/reader036/viewer/2022062804/56649d6b5503460f94a4a90a/html5/thumbnails/48.jpg)
