Asbestos awareness
Asbestos Awareness

  • What is Asbestos?

    • Naturally Occurring Silicate Minerals

      • Amosite (Brown)

      • Chrysotile (White)

      • Crocidolite (Blue)

      • Tremolite

      • Actinolite

      • Anthophyllite


Asbestos awareness1
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 awareness3
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 awareness6
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 awareness7
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 awareness9
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 awareness12
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 awareness2
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.
