  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.

  32. Dates of Usage • 1970 end use of Crocodile. • 1974 end use of sprayed coatings. • 1985 end use of AIB. • 1993 end of manufacture of roofing felt. • 1999 end use of cement, gaskets, friction materials.

  33. You don’t have to be Einstein to understand and appreciate the benefits of managing asbestos in buildings
