  2. Objectives • Asbestos Awareness? • When is Asbestos Potentially Dangerous? • What are the Potential Adverse Health Effects of Overexposure? • How Does One Avoid Unnecessary Exposure? • Regulatory Compliance • Lead Awareness? • When is Lead Potentially Dangerous? • What are the Potential Adverse Health Effects of Overexposure? • How Does One Avoid Unnecessary Exposure? • Regulatory Compliance

  3. Asbestos Awareness • What is Asbestos? • Naturally Occurring Silicate Minerals • Amosite (Brown) • Chrysotile (White) • Crocidolite (Blue) • Tremolite • Actinolite • Anthophyllite

  4. Asbestos Awareness • What is Asbestos? • Resilient • Resistant to Chemicals • Resistant to Heat • Does Not Evaporate • Does Not Dissolve in Water • Very Stable in the Environment • Virtually Indestructible

  5. Asbestos Awareness • What is Asbestos? • Asbestos has Many uses Because of Resilient Properties • Used in Over 3,000 Different Products • Mixed with Other Materials to Form Products known as Asbestos Containing Materials (ACM) • Asbestos Containing Materials May Contain Small or Large Amounts of Asbestos • Potentially between 1% and 100% Asbestos Content

  6. Asbestos Awareness • Where are Asbestos Containing Materials (ACM) found? • ACM is Located in Nearly all Buildings, Workplaces and Areas of the University • Wall, Ceiling, Pipes, Boiler, Fire Proofing, Spray-on • Putties, Caulks, Cements, Textures, Mastic, Glues • Ceiling Tiles, Floor Tiles, Roofing, Siding • Acoustical Plasters, Transite Materials, Insulation • Fire doors, Electrical Wire Insulation, Gaskets • These and MANY More Building Materials…

  7. Asbestos Awareness • Where is ACM found?

  8. Asbestos Awareness • Where is ACM found?

  9. Asbestos Awareness • When is Asbestos Potentially Dangerous? • Most Dangerous When it is Friable • “Friable’ means that the ACM is easily crumbled by hand pressure, which release fibers into the air. • Non-Friable Release Fibers if the Material is Damaged or Disturbed using Tools or Mechanical Methods

  10. Asbestos Awareness • When is Asbestos Potentially Dangerous? • Most Dangerous When it is Friable • Pipe Insulation and Spray-on Fireproofing are Examples of Friable Materials • Transite Siding and Floor Tile are Examples of Non-Friable Materials • Sanding, Drilling, Broken, Ground, Buffed, Cut, Sawed, Struck or Otherwise Impacted can Cause ACM to Release Fibers

  11. Asbestos Awareness • What are the Potential Adverse Health Effects of Overexposure? • ACM is generally not considered to be harmful unless it releases dust or fibers into the air where they can be inhaled. • Many of the fibers will become trapped in the mucous membranes of the nose and throat where they can then be removed, but some may pass deep into the lungs. • Once they are trapped in the lungs, the fibers can cause health problems.

  12. Asbestos Awareness • What are the Potential Adverse Health Effects of Overexposure? • Asbestos (Scaring of the Lungs) • Lung Cancer • Mesothelioma (Rare form of Cancer)

  13. Asbestos Awareness • What are the Potential Adverse Health Effects of Overexposure? • There are two determining factors that seem to relate to the probability of developing these diseases: • The amount and duration of Exposure – Persons exposed frequently over a long period of time are more at risk, making it important to minimize exposures • Whether or not one smokes Cigarettes – The first thing a smoker should do to reduce their risk of developing lung cancer is to stop smoking

  14. Asbestos Awareness • Note: Self-help smoking-cessation materials are available through the Employee Health Promotion Program in the Johnson Center Building.

  15. Asbestos Awareness • How Does One Avoid Unnecessary Exposure? • Because one cannot tell if a building material contains asbestos by looking at it… • ASSUME IT DOES • Never break, saw, cut, hammer, drill, damage, disturb or move any ACM or suspect materials. • If you identify materials that have been damaged, this is considered a “spill”, do not clean up spills yourself. Instead, • CONTACT UNM SAFETY AND RISK SERVICES at 277-2753

  16. Asbestos Awareness • How Does One Avoid Unnecessary Exposure? • Because one cannot tell if a building material contains asbestos by looking at it… • ASSUME IT DOES • Never break, saw, cut, hammer, drill, damage, disturb or move any ACM or suspect materials. • If you identify materials that have been damaged, this is considered a “spill”, do not clean up spills yourself. Instead, • CONTACT UNM SAFETY AND RISK SERVICES at 277-2753

  17. Asbestos Awareness • Any questions before we move on to Lead Awareness?

  18. Lead Awareness • What is Lead (Pb)? • Used as a Major Pigment in Paints up until the late 1940’s, but continued to be used in some pigments and as drying agents • Had other applications at UNM as well…

  19. Lead Awareness • Where is Lead (Pb) Found? • Primarily in Paints as Pigments • May also be found in: • Weights • Shielding • Putties • Mechanical/Electrical Equipment • Still has various other uses in Laboratories and Facilities…

  20. Lead Awareness • What is Lead-Based Paint (LBP)? • HUD defines LBP as paint containing 0.5% or 5000 parts per million (ppm) • Lead is an excellent corrosion inhibitor and pigment in paint • Buildings constructed or painted prior to the early 1980’s may contain lead compounds in the paint • Still has some specialized uses

  21. Lead Awareness • What are the Hazards? • Lead may be absorbed into the body by • Ingestion (eating) • Absorption (through skin) • Inhalation (breathing) • Children have suffered from lead poisoning by eating LBP flakes (chips) • Lead is a “cumulative” toxin

  22. Lead Awareness • What are the Hazards? • Chronic adverse health effects are: • Blood-Forming Systems: Decreased hemoglobin (oxygen carrying material in blood), anorexia and anemia • Central Nervous System: Fatigue, dullness, memory loss and possible seizures • Urinary Systems: Possible kidney damage with progression to kidney dialysis • Reproductive Systems: Decreased sex drive and possible risk of birth defects

  23. Lead Awareness • What are the Precautions? • Training • Housekeeping • Hand Washing Facilities • Personal Protection Equipment

  24. Lead Awareness • REMEMBER: An ounce of prevention is worth a pound of cure. • Always remember to wash your hands before smoking or eating. • You may ask for and use a dust mask in potentially dusty situations, where free silica may also be present. • Protective equipment will help protect your health and assure your safety.

  25. Conclusions • Questions?
