What is Asbestos?

Asbestos is the name applied to six naturally occurring minerals that are mined from the earth. The different types of asbestos are:

Amosite

Chrysotile

Tremolite

Actinolite

Anthophyllite

Crocidolite

Chrysotile is the most common,

and is found in over 95% of all

asbestos containing material.

Asbestos Properties

  • All types of asbestos tend to break into very tiny fibers.
  • Once released into the air, they may stay suspended there for hours or even days.
  • Asbestos fibers are virtually indestructible.
  • The properties of asbestos are what makes it
  • so dangerous.
  • Once inhaled it is impossible to remove from
  • lung tissue.

slide5

Where is Asbestos Found?

  • Asbestos can be found virtually anywhere and is still mined in other countries.
    • Sprayed on fire proofing and
    • insulation in buildings
    • Insulation for pipes and boilers
    • Wall and ceiling insulation
    • Ceiling tiles
    • Floor tiles
    • Putties, caulks, and cements

slide6

Where is Asbestos Found ?

  • Roofing shingles
  • Siding shingles on older buildings
  • Wall and ceiling texture in older buildings
  • and homes
  • Joint compound in older buildings
  • and homes
  • Brake linings and clutch pads

Asbestos Properties

  • Asbestos is most hazardous when it is friable.
    • The term "friable" means that the asbestos is easily crumbled by hand, releasing fibers into the air.
    • When asbestos is friable, it is easily inhaled.
    • Sprayed on asbestos insulation is highly friable.
  • Asbestos is non-friable when it is bound into other fibers. These fibers are harder to break down, but can be released by drilling, sanding or grinding the material.
    • Asbestos containing floor tile and asbestos containing lab benches are an example of non-friable asbestos.
  • IT IS IMPORTANT TO CONTACT THE ENVIRONMENTAL HEALTH AND SAFETY DEPARTMENT AT EXT. 4078 BEFORE WORK IS PERFORMED.

slide8

Health Effects

  • The body cannot break down or remove asbestos fibers once they are lodged in lung or body tissues.
  • They remain in place where they can cause disease.

8

diseases associated with asbestos
Diseases Associated with Asbestos

Asbestosis

  • Caused by repeated, long-term exposure to airborne asbestos

Lung Cancer

  • The risk of lung cancer increases with repeated exposure to airborne asbestos

Mesothelioma

  • Can be caused by even a minimal exposure to airborne asbestos and is generally fatal

Injured Lung

slide10

Avoiding Asbestos Exposure

  • If you do not know whether something is asbestos or not, assume that it is until it is verified otherwise.
  • You cannot tell if floor or ceiling tiles contain asbestos just by looking at them.
  • If you have reason to suspect that something is asbestos DO NOT DISTURB IT.

asbestos program notification
Asbestos Program & Notification
  • Asbestos Program Notification Memo
    • The memo provides a brief summary of the results of a survey conducted to determine the presence, location, and condition of asbestos on campus
    • Click link to view memo
  • IF YOU HAVE ANY QUESTIONS OR YOU WOULD LIKE MORE INFORMATION ON ASBESTOS PLEASE CONTACT EHS @ 594-4078
