BUILDING PATHOLOGY : DELETERIOUS MATERIALS

MATERIALS HAZARDOUS TO HEALTH
1. ASBESTOS
  1. Can be found in any building built before 2000, regularly used in 1950s until late 1990s
  2. Types of asbestos
    1. Crocidolite (blue)
    2. Amosite (brown)
    3. Chrysolite (white)
  3. Health risks
    1. Mesothelioma
    2. Asbestos related lung cancer
    3. Asbestosis
    4. Pleural thickening
  4. Types of survey
    1. Management survey
      1. Involves minor intrusion and asbestos disturbance to make materials assessment
        Shows ability of ACM, if disturbed, to release fibres into air.
      2. Area must be vacated during survey
    2. Refurbishment / demolition survey
      1. All ACMs identified before structural work beings
      2. Involves destructive inspection and asbestos disturbance
      3. Area must be vacated and certified "fit for reoccupation" after survey is completed
2. LEAD
MATERIALS DAMAGING TO BUILDINGS
1. HIGH ALUMINA CEMENT CONCRETE
2. CALCIUM CHLORIDE
  1. Multi Storey Car Parks
3. COMPOSITE CLADDING PANELS
4. BRICK SLIPS
MATERIALS THAT CAN HAVE HARMFUL EFFECTS ON BUILDINGS
1. MARBLE CLADDING
2. MASONRY ENCASED STEEL
