Title: ASBESTOS RISK


1
ASBESTOS RISK MANAGEMENT
2
Summary
  • Asbestos.
  • The health risk.
  • In buildings.
  • Background to regulation.
  • Outline of duty to manage.
  • Review of consultation.

3
What is asbestos
  • Asbestos is the name for a group of naturally
    occurring silicate minerals that can be separated
    into fibres.
  • The fibres are strong durable and resistant to
    heat and fire. They are also long thin and
    flexible so that they can be woven into cloth.
  • Because of these qualities asbestos has been used
    in thousands of consumer, industrial maritime
    automotive scientific and building products.
  • During the twentieth century some 30 million
    tonnes of asbestos were used in industrial sites
    schools shipyards and commercial buildings.

4
What is asbestos
  • It is of two principal classes the amphiboles and
    the serpentines the former of relatively minor
    importance.
  • Chrysotile is in the serpentine class and
    constitutes about 95 of the worlds supply of
    asbestos, of which three quarters is mined in
    Quebec.
  • Other large deposits exist is South Africa.

5
AMOSITE (Brown)
  • Brown or grey straight fibres.
  • Belongs in the amphibole group and contains iron
    and magnesium.

6
CHRYSOTILE (WHITE)
  • A white curly fibres accounts for 95 of asbestos
    in products.
  • It is a member of the serpentine group. It is
    magnesium silicate.

7
CROCIDOLITE (BLUE)
  • Amphibole group.
  • Takes the form of blue straight fibres.
  • It is a sodium iron magnesium silicate.

8
The problem
  • Over 3000 people a year die from asbestos
    related diseases.
  • There is usually along delay between the first
    exposure and subsequent symptoms of the disease.
  • Between 15 and 60 years.

9
Asbestos related disease
  • ASBESTOSIS
  • a scarring of the lung that leads to breathing
    problems.
  • Workers who have had high long exposures are
    often affected with asbestosis.
  • MESOTHELIOMA
  • is a malignant form of lung cancer that affects
    the cells that form the lining around the outside
    of the lungs.

10
The problem
  • Between the 1950s and 1970s asbestos was used
    widely in the UK as building materials.
  • Thousands of tonnes of asbestos are still in
    buildings today.
  • Over 1.5 million buildings still contain some
    form of asbestos.

11
The problem
  • 25 of people still dying from asbestos related
    disease once worked in the construction industry.
  • Pre 1988 the Asbestos Regulations were aimed at
    those working in asbestos factories and for
    asbestos removal contractors.
  • The regulations did not cover those who might
    come into contact with asbestos accidentally.

12
Who are these people
  • Heating and ventilation engineers.
  • Roofing contractors.
  • Electricians.
  • Joiners.
  • Plumbers.
  • Gas fitters.
  • Demolition workers.

13
What have we done already
  • The 1998 Amendment of the Control of Asbestos at
    Work Regulations
  • extended there scope to cover incidental
    exposure,and,
  • made it clear that CAWR applied to all workers
    who might come into contact with asbestos.
  • The 1998 Amendment to the Asbestos (licensing)
    Regulations.
  • The 1999 Asbestos (prohibitions)Regulations

14
A part of the jigsaw is still missing
  • Contractors not aware that they were working on
    asbestos materials.
  • No one was managing the risk from asbestos in
    buildings.

15
Options
  • Removal of all asbestos containing materials from
    buildings.
  • Introduction of a single duty to survey for
    asbestos.
  • Introduction of new regulation to manage the risk
    from asbestos.

16
Remove all asbestos ?
  • NO
  • Asbestos can serve a useful purpose e.g fire
    protection.
  • If in good condition,and in a position where it
    cannot be damaged or disturbed, it poses NO RISK.
  • Removal would be prohibitively expensive.
  • Disposal of waste would generate immediate
    problems.
  • Removing asbestos creates an additional
    unnecessary risk for removers.

17
A single duty to survey
  • NO
  • Only the first step. Resources are better spent
    on managing the risk.
  • Practical difficulties e.g who would undertake
    the survey and who would pay?
  • Survey information goes out of date. The
    condition of asbestos materials deteriorates.

18
A new duty to manage risk ?
  • YES
  • Introduces it as a new regulation in the CAWR
    1987.
  • To focus on a duty to manage the risk from
    asbestos in buildings.
  • A new ACOP to back up regulations and provide
    guidance to the designated duty holders.

19
Duty holder to
  • Take reasonable steps to identify asbestos
    containing materials in buildings by
  • Looking at plans etc,
  • Consultation of others e.g. architects employees
    etc.
  • Carrying out a detailed inspections of the
    building.

20
Types of survey
  • TYPE 1
  • Location and assessment survey (presumptive
    survey).
  • Assess the presence of ACMs.
  • Any materials which can reasonably be expected to
    contain asbestos will be presumed to contain
    asbestos.

21
Types of survey
  • TYPE 2
  • Full access sampling and identification
    survey(sampling survey).
  • As type 1.
  • Samples are collected an analysed for the
    presence of ACMs.

22
Types of survey
  • TYPE 3
  • Full access sampling and identification survey
    (pre/demolition or refurbishment).
  • Access all areas.
  • May involve destructive inspection.

23
Duty holder to
  • Assess the risk from materials.
  • If asbestos is in good condition.
  • Leave it in place and introduce a management
    system.
  • If its in poor condition.
  • Encapsulate or seal it or removal by licensed
    contractors.

24
Duty holder to
  • Prepare a management plan and,
  • Where materials are to remain in the building
  • Inform others of condition and locations ACMs.
  • Carry out regular inspections on ACMs condition.
  • Review and revise management plan as needed.

25
Record keeping
  • Survey report.
  • Risk assessments.
  • Management plan.
  • Paper and computer based.
  • Ease of updating.
  • Arrangements for long term storage of records.
  • Determine who will need access.

26
Maintenance of Management Plan
  • Fits with other systems.
  • Permit to work.
  • Strict control of contractors operations.
  • Mentioned in emergency and contingency
    procedures.
  • Arrangements for monitoring and reviewing plan.

27
Review of consultation
  • Consultation took place in 2000.
  • Encouraged review of two primary areas.
  • Exactly who will be duty holder.
  • Which buildings the propped regulations cover.

28
Who has a duty
  • The employer in occupation.
  • Legal duties placed on others.
  • Where
  • The workplace and the common areas in rented
    accommodation.
  • This extends to some domestic premises.

29
Further Consultation
  • The need to consult timetable 2002.
  • Supporting Guidance
  • ACOP will give guidance on
  • Identifying asbestos maintaining a register.
  • Assessing the risk.
  • Preparing an action plan.
  • Setting up suitable management systems.

30
Asbestos Materials
  • Spray coatings.
  • Pipe insulation.
  • A.I.B
  • Cement products.
  • Composite materials.
  • Textured coatings.
  • Sandwich materials.

31
Typical Locations
  • Roof and exterior walls.
  • Boilers and pipework.
  • Ceilings.
  • Flooring materials.
  • Air ducting.
  • Domestic appliances.

You dont have to be Einstein to understand and
appreciate the benefits of managing asbestos in
buildings
