               Asbestos?
      Is a mineral, mined primarily in Africa, Brazil,
China, and Canada, but is not hazardous in it’s
natural state. Asbestos becomes hazardous when
it is broken up and the fibers and dust become
suspended in air in the breathing zone.
            Asbestos Uses...
   Fire proofing              1890-1970 -25 million
    – Can be woven into         tons used.
      cloth                    1930-1941 widest use,
   Acid resistant              especially in
   High tensile strength       shipbuilding.
   Excellent insulator        1941-1974 use
                                decreased.
                               1976 all new vessels
                                and constructions
                                asbestos free
     Three Common Types of
            Asbestos
   Chrysotile (white      Most common used 95%
    asbestos)               found in buildings in US.

                           Second most likely to be
   Amosite (brown          found in buildings.
    asbestos)               (brown in natural state)


   Crocidolite (blue      Used in high
                            temperature insulation
    asbestos)
                            and decorative
                            applications.
       Common Applications
   pipe lagging           cement
   insulation             brake pads
   gaskets material       clutch plates
   welder’s curtains      spackling/joint
   sheathing               compounds
   floor tiles            shingles
   ceiling tiles          cigarette filters
           Identification
 Inspections conducted by certified AHERA
  inspectors.
 Laboratory analysis. (only way to prove)
    Management of Asbestos.
   The Coast Guard mostly manages asbestos in
    place once it has been identified. Only the Yard
    and ISC Ketchikan have trained personnel who
    can conduct asbestos removal projects.
    – Most asbestos rehab is contracted out.
    Hazardous Determination
   Asbestos is only hazardous when it is in a friable (breaks
    easily) state.
   Removal, cutting and other abrasive work can release the
    asbestos fibers.
   Best course of action is to
    – maintain in place
    – isolate
    – encapsulate.

   Removal is only authorized by trained professionals or in
    case of an emergency (shipboard only).
           Health Hazard
 Asbestosis
 Lung cancer
 Mesotheiloma
 Colon Cancer
 Asbestos and smoking cause a Synergistic
  effect
      • 1 + 1= 10
    Units Management Plan
 Written instruction/Management plan
 Inventory of ACM or PACM
 Proper labeling of all ACM
 Annual inspection
 Annual Training
 Informing contractors
                     Lead
   Lead is a soft, low temperature melting,
    corrosive-resisting metal used since ancient
    time.
   Has history of documented health effects of
    over exposure for as long as it has been
    used.
    Routes of Lead Exposure
   Inhalation

   Ingestion

   Injection
             Lead Affects:
   Blood               Digestive System
   Kidneys             Muscles & Bones
   Nervous System      Reproductive System
Use of Lead Paint
   Prohibited
          Lead Based Paint
   Not written policy but a recommendation
   MLC (kse) can provide guidance.
         Program Elements
   Written instruction
   Training
   Inventory
   IH sampling
   Medical Monitoring
   Engineering controls
   Signs
        Protective Clothing
