  1. October 2010 Asbestos Awareness (OEMP005) Occupational Health Department Occupational Health Department NOTE: Detailed speakers notes included to support delivery of material.

  2. Outline • What is asbestos? • What are the health concerns? • Common materials found at Vale • Asbestos installation/removal procedures • Inadvertent discovery process

  3. What is Asbestos?

  4. Asbestos and Properties of Asbestos There are 3 main types: CHRYSOTILE White Asbestos AMOSITEBrown Asbestos CROCIDOLITEBlue Asbestos

  5. Friable Non-Friable Asbestos Containing Material (ACM) In Ontario, ACM means material that contains 0.5% or more asbestos by dry weight. ACM can be divided into two groups on the basis of their friability. Definitions: ‘friable material’: means material that when dry can be crumbled, pulverized or powdered by hand pressure. When ACM does not meet the above definition, it is considered to be a ‘non-friable ACM’.

  6. Asbestos Containing Material (ACM) A binder such as cement, vinyl or asphalt can be used to lock the asbestos fibres within the matrix rendering an ACM non-friable. Products made from non-friable material will generally release fibres only when they are cut, shaped or crushed. The installation and removal of such products can be classified as “Type 1, 2 or 3” Operations.

  7. What are the potential health effects from exposure to asbestos?

  8. Health Risks • Asbestos fiber bundles can split and small fine fibres can break away. • If inhaled the body is able to resist most of the large particles, but fine fibres, too small to see, can lodge deep in the lungs. • This can cause these diseases: Asbestosis Lung cancer Mesothelioma

  9. Risk Factors Various factors determine how exposure to asbestos affects an individual: • Exposure concentration • Exposure duration • Exposure frequency • Size, shape and chemical makeup of asbestos fibers

  10. When Is Asbestos a Risk to Health? • Consider the type/content of material: • How well is the asbestos bonded into its matrix? • Is it likely to contain a small or large amount of asbestos? • Consider the condition: • GOOD (low risk) e.g. sealed, painted. • Damaged, and the extent of damage. (High risk)

  11. Asbestos containing material found in Vale operations

  12. Asbestos Products The following are examples of non-friableACM: • Transite sheets - flat or corrugate Used as: roofing, walls, ceilings, panels/partitioning, under stairs, door-linings, rainwater pipes / guttering • Floor tiles/ roof tiles • Car parts (brake clutch linings) • Gaskets Note: An ACM non-friable product may become friable if the matrix becomes deteriorated. All ACM material should be confirmed in the survey beforecommencing any work on the product.

  13. Asbestos Products • The following products are example of ACM that are classified as friable • Lagging - to boilers, pipes • Sprayed coatings to - ceilings; insulation Torn pipe lagging Pipe insulation

  14. Asbestos Products at Vale Pipe Gallery siding (transite), Crushing Plant siding (transite) Parging and cement around tank opening Floor Tile Some ceiling tiles may contain asbestos

  15. Asbestos Products at Vale Elbows Gasket (between two pipes at sealing section) Pipe Lagging, Gaskets and Woven Asbestos

  16. Asbestos Inventory • Each facility is required to have an Asbestos inventory. • The inventory documents the location, the product that contains asbestos including the types and concentration of asbestos. • Each site has an Occupational Health contact • Addressing asbestos related issues • Conducts annual survey of the materials identified in the inventory

  17. Installation/Removal Procedures:Classification of Work

  18. Asbestos “Operations” • Work on Asbestos Containing Material (ACM) is divided into three categories: • Type 1 Operation • Type 2 Operation • Type 3 Operation • The operation type is dependant upon various factors including the nature of the work and the amount of ACM involved.

  19. Asbestos “Operations” • Vale employees may be involved in Type 1 Operations (e.g. ACM gasket removal or Transite panel replacement). • You must be trained before doing work that is designated as a Type 1 Asbestos Operation • Type 2 and 3 Operations are only performed by qualified asbestos contractors.

  20. Identification of Potential ACM • Do not work on or disturb any materials until you have confirmed that the material does not contain asbestos. • To confirm the absence or presence of asbestos, contact your Occupational Health site contact. • Do not sample the material yourself

  21. Inadvertent discovery of suspected asbestos
