Asbestos
Definition:A group of six naturally occurring minerals that can be separated into fibers.
Amosite, Chrysotile, Tremolite, Actinolite, Anthophyllite, and CrocidoliteFibers DO NOT evaporate into air or dissolve in water.
Asbestos materials are referred to as being either “Friable” or “Non-friable”.Asbestos Containing Material (ACM) – a material containing greater than 1% asbestos content
UW-Eau ClaireFacilities Management
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 wrappingSome ceiling tiles
UW-Eau ClaireFacilities Management
Non-friable Asbestos Non-friable asbestos is usually found bonded into other materials.
It’s 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 tilesAsbestos cement pipesTransit boardsRoofing shingles
Asbestos cement (flue infill)
UW-Eau ClaireFacilities Management
Common Materials that May Contain AsbestosSurfacing Materials:
Sprayed on and troweled on surfaces for acoustical, decorative, or fireproofingPlaster and fire proof insulation
Thermal System Insulation:Pipe wrap, cement, gaskets, and etc.
Materials used to inhibit heat transfer or condensation
Miscellaneous Materials:Floor tiles
Most 9” floor tiles and few 12” in buildings build prior to 1980
Ceiling tiles, roofing felt, fabrics Shingles, or siding
Friction Products such as:Automobile ClutchBrake PadsTransmission Parts

Common Materials that May Contain Asbestos

Common Types Of Asbestos
Note: The general use of asbestos is now banned. Blue and BrownAsbestos banned in 1985, white in 1999.
UW-Eau ClaireFacilities Management
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.
UW-Eau ClaireFacilities Management
Human Hair
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.
UW-Eau ClaireFacilities Management
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.
Who is at risk?
Anybody that disturbs ACM sufficiently to put dust in the air!
Demolition WorkersBuilding Maintenance WorkersGas FittersJoinersElectriciansHeating and ventilating engineersPlumbers

Asbestos Work ClassificationsClass 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 WorkActivities 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, troweled-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.
UW-Eau ClaireFacilities Management
Asbestos Work Classifications
Class IV Asbestos WorkIncludes 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 FP&M 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.
UW-Eau ClaireFacilities Management
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.Custodians use of Wet Methods, wetting agents during asbestos handling, mixing, removal, cutting, application, and cleanup, unless infeasible due to creation of other hazards.Low abrasion pads should be used at speeds below 300rpm.
Work Practice Controls for Class III & IV Asbestos Work
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.Broken and fallen ceiling tiles should be left in place until identified. Only after they have been identified as safe may they be removed.Asbestos tiles will be removed by asbestos abatement workers.

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
UW-Eau ClaireFacilities Management
Potential DiseasesAsbestosis
A breathing disorder caused by inhaling high levels of asbestos fibers. Primary effects are scarring of the lung tissueSigns 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
UW-Eau ClaireFacilities Management
Potential DiseasesLung 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 breathingChest painsHoarsenessAnemia
The risk for smokers is 80 – 90 times greaterSymptoms may appear after about 15 to 30 years, depending on the frequency and duration of asbestos exposure
UW-Eau ClaireFacilities Management
Potential DiseasesMesothelioma
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 breathPleural effusionChest pains
No increased risk for smokersSymptoms may appear 15 to 40 years after exposure
UW-Eau ClaireFacilities Management
Ways to Protect YourselfDo 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 can’t even see it
Do not enter an asbestos abatement areaReport uncovered friable asbestos or damaged asbestos material to supervisorDo not cut or drill transit board or pipeWhen removing ventilation system filters, do not shake the filters to remove dust
UW-Eau ClaireFacilities Management
Respirators & Medical SurveillanceRespirators
Use of respirator during work activities Class I & II for contractors.Class III & IV for qualified FP&M employees must follow a Respiratory Protection Program in compliance with OSHA requirements.
Medical SurveillanceMust be instituted for employees who for a combined total of 30 or more days per year are exposed at or above a permissible exposure limitAny 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.
