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 allasbestos 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 itso dangerous.

•Once inhaled it is impossible to remove fromlung tissue.

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

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.

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.

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.
