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

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

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

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…

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

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
asbestos awareness8
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.

Asbestos Awareness
  • What are the Potential Adverse Health Effects of Overexposure?
    • Asbestos (Scaring of the Lungs)
    • Lung Cancer
    • Mesothelioma (Rare form of Cancer)
asbestos awareness10
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

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

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

  • Any questions before we move on to Lead Awareness?
lead awareness
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…
lead awareness1
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…

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
lead awareness3
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
lead awareness4
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
lead awareness5
Lead Awareness
  • What are the Precautions?
    • Training
    • Housekeeping
    • Hand Washing Facilities
    • Personal Protection Equipment
lead awareness6
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.
