Presentation Transcript
introduction
Introduction
  • Asbestos is naturally occurring fibrous mineral silicate.
  • Six different types divided into two mineral groups.
  • Serpentine and Amphiboles are the two mineral groups.
  • Asbestos breaks down into fibers.
  • Fibers take on aerodynamic quality and behave in a gas-like manner.
introduction1
Introduction

Serpentine Mineral Group:

  • Chrysotile white asbestos is most common in US.
  • Fibers are long, wavy, hollow and snake-like in appearance.
  • Hygroscopic-easily absorbs moisture.
  • Mined since 1870’s.
introduction2
Introduction

Amphiboles Mineral Group:

  • Amosite is brown in color and was first mined in South Africa in 1911.
  • Fibers are short, solid or dowel-like in appearance.
  • Fibers are hydrophobic.
  • Crocidolite is blue in color and very rare.
friable and non friable acm
Friable and Non-Friable ACM

EPA Defintion of Friable:

Easily crushed, crumbled or pulverized into powder by hand pressure.

examples of friable acm
Examples of Friable ACM
  • Spray on fire proofing
  • Plaster
  • Pipe insulation
  • Boiler breeching
  • Decorative Plaster
  • Sheet rock
examples of non friable acm
Examples of Non-Friable ACM
  • Floor tiles
  • Mastics and adhesives
  • Roofing materials
  • Transite
  • Window caulking
  • Siding and Shingles
  • Brake pads
