Asbestos

• Definition
• A group of naturally occurring minerals that can
  be separated into fibers.
• Fibers DO NOT evaporate into air
  or dissolve in water.
• Asbestos materials are referred to as being
  either Friable or Non-friable.

4
Friable Asbestos

• Friable materials can be crushed to powder by
  hand pressure when dry, and release small fibers
  as they crumble.
• Friable asbestos containing materials include
• Sprayed-on asbestos insulation.
• Some pipe wrapping
• Some ceiling tiles

5
Non-friable Asbestos

• Non-friable asbestos is usually found bonded into
  other materials.
• Its fibers are harder to break down into powder,
  but can still be released by cutting, grinding or
  sanding.
• Non-friable asbestos containing materials
  include
• Floor tiles
• Asbestos cement pipes
• Transit boards
• Roofing shingles

6
Common Materials that May Contain Asbestos

• Surfacing Materials
• Sprayed or troweled on surfaces for acoustical,
  decorative, or fireproofing
• Plaster and fire proof insulation
• Thermal System Insulation
• Pipe wrap, cement, gaskets, and etc.
• Materials used to inhibit heat transfer
  or condensation
• Miscellaneous Materials
• Floor tile, ceiling tile, roofing felt,
  fabrics, shingles, or siding

7
Common Types Of Asbestos
Amosite
Chrysotile
Crocidolite
8
Common Types Of Asbestos

• Known as White asbestos it has tiny, fine
  fibers that are, smooth, flexible, and curly.
• It is used in asbestos cement, vinyl
  floor tiles, insulation materials, oven
  gloves, etc.
• It makes up approximately 90 of asbestos
  used world-wide.

Chrysotile
9
Common Types Of Asbestos Cont.

• Known as brown asbestos it has long, brittle,
  needle-like fibers.
• It is used in high-friction application such as
  brake shoes and clutches.
• Its fibers may be 700 times smaller than a human
  hair.

Amosite
Human Hair
10
Common Types Of Asbestos Cont.

• Know as blue asbestos it is soft, silky, and
  flexible. It is harder than other asbestos but
  still flexible and strong.
• It was mainly used in thermal lagging
  and sprayed coating
• It has been found in imported insulation
  board.
• Used in wrapping, sheeting,
  piping and boiler wrap.
• It is approximately 10 of
  the asbestos used in the US.

Crocidolite
11
Asbestos Work Classifications

• Class I Asbestos Work
• Activities involving the removal of TSI and
  surfacing ACM.
• Class II Asbestos Work
• Activities involving of ACM which is not TSI or
  surfacing material. This includes, but is not
  limited to
• Removal of asbestos-containing wallboard, floor
  tile sheeting.
• Roofing and siding shingles and construction
  mastics.
• Class III Asbestos Work
• Activities involving repair and maintenance
  operations, where ACM, including TSI and
  surfacing PACM, is likely to be disturbed, for
  example
• TSI with asbestos containing material applied to
  pipes, fittings, boilers, breeching, tanks, ducts
  or other structural components to prevent heat
  loss or gain.
• Surfacing ACM that has been sprayed, toweled-on
  or otherwise applied to surfaces such as
• Acoustical plaster on ceilings and fireproofing
  materials on structural members, or other
  materials on surfaces for acoustical,
  fireproofing, and other purposes.

12
Asbestos Work Classifications

• Class IV Asbestos Work
• Includes maintenance and custodial activities
  during which employees contact but do not disturb
  ACM or PACM and activities to clean up dust,
  waste and debris resulting from Class I, II, and
  III activities.
• Qualified FPM employees, or contractors,
  cleaning up debris and waste in a regulated area
  where respirators are required shall wear
  respirators.
• Waste and debris in areas where friable TSI or
  surfacing materials is accessible shall be
  assumed to contain asbestos.

13
Work Practice Controls for Class III IV
Asbestos Work

• Drilling, cutting, abrading, sanding, chipping,
  breaking of ACM should be performed using drop
  cloths and mini-enclosures or glove bag systems
  or another isolation method.
• Vacuum cleaners equipped with HEPA filters should
  be used for cleanup.
• Use of Wet Methods, wetting agents during
  asbestos handling, mixing, removal, cutting,
  application, and cleanup, unless infeasible due
  to creation of other hazards.
• Prompt disposal of wastes contaminated with
  asbestos in leak-tight containers.
• Respirators and other appropriate PPE shall be
  worn where TSI or surfacing material is involved.

14
Inhalation is the most common form of entry to
body

• The body cannot break the asbestos
  fibers down or remove them.
• Fibers can become trapped in the
  mucous membranes of the nose or
  throat, or pass deep into the
  lungs.
• Once they are lodged in the lung or body tissues,
  they remain in place where they can cause
  diseases.

General Health Effect of Asbestos
15
Potential Diseases

• Asbestosis
• A breathing disorder caused by inhaling high
  levels of asbestos fibers.
• Primary effects are scarring of the lung tissue
• Signs and symptoms of asbestosis include
• Shortness of breath
• Decreased tolerance for physical activity
• Coughing
• Chest pain
• Symptoms may appear anywhere from 10 to 20
  years after initial exposure

16
Potential Diseases

• Lung Cancer
• A serious tumor of the bronchi covering for
  people exposed to asbestos.
• Signs and symptoms of lung cancer include
• Coughing and a change of breathing
• Chest pains
• Hoarseness
• Anemia
• The risk for smokers is 80 90 times greater
• Symptoms may appear after about 15 to 30 years,
  depending on the frequency and duration of
  asbestos exposure

17
Potential Diseases

• Mesothelioma
• A rare form of cancer which most often occurs in
  the thin membrane lining of the lungs, chest,
  abdomen, and heart.
• Signs and symptoms of Mesothelioma include
• Shortness of breath
• Pleural effusion
• Chest pains
• No increased risk for smokers
• Symptoms may appear 15 to 40 years after exposure

18
Ways to Protect Yourself

• Do not touch or disturb any surface
  materials that may contain asbestos.
  If you are uncertain DO NOT TOUCH
• Exposure to .1 fiber/cubic centimeter in an 8
  hour day is potentially hazardous. This amount is
  so small you cant even see it
• Do not enter an asbestos abatement area
• Report uncovered friable asbestos or damaged
  asbestos material to supervisor
• Do not cut or drill transit board or pipe
• When removing ventilation system filters, do not
  shake the filters to remove dust

19
Respirators Medical Surveillance

• Respirators
• Use of respirator during work activities Class I
  II for contractors.
• Class III IV for qualified FPM employees must
  follow a Respiratory Protection Program in
  compliance with OSHA requirements.
• Medical Surveillance
• Must be instituted for employees who for a
  combined total of 30 or more days per year are
  exposed at or above a permissible exposure limit
• Any day in which a worker engages in Class II or
  III operations (or a combination thereof) on
  intact material for one hour or less, while using
  appropriate work practices, shall not be counted.

20
Summary

• Recognize potential asbestos locations
• Understand the health risks
• Do not disturb asbestos
• Understand ways to protect yourself
• Do not handle asbestos containing materials
  unless authorized to do so
