Asbestos AwarenessAsbestos Awareness


Objectives

• What is asbestos

• Where can it be found

• What are the health problems associated with exposure to asbestos

• How can exposure occur

• OSHA Requirements

• Fermilab Policy


Asbestos

• Group of Naturally Occurring Minerals

• Fibrous Structure

• Different Types

• Most Common (95%)– Chrysotile (White)– Amosite (Brown)


Good Things About Asbestos

• Good insulator (heat and electricity)

• High tensile strength

• Resistant to corrosives

• Doesn’t burn

• Inexpensive

• Fibrous – can be used in a variety of ways


Uses – Prior to 1980

• Ceiling tiles• Drywall taping

compound• Adhesives and mastics• Thermal system

insulation• Roofing felts• Gaskets

• Vibration dampers• Cement sheet

(transite)• Floor tile• Valve packing and

insulation• Fire Resistant drywall• Sprayed-on

fireproofing


Health Concerns

• Inhaled or swallowed

• Asbestosis – scarring of lung – 20 year latency period

• Lung Cancer – 20 to 30 year latency period

• Mesothelioma – cancer of the lining of lung – 30 year latency period – rare

• Digestive Tract Cancer


How Much Is Too Much?

• Studies done on people exposed to asbestos in the course of their work show increased risk

• Much higher concentrations of asbestos than the general public

• Cannot state that there is a threshold below which risk of cancer is not increased

• OSHA – 8 hour time-weighted-average of 0.1f/cc• Smoking increases risk


So What?

• If you work around asbestos containing building materials which are damaged or deteriorated there is a potential you may be exposed to asbestos fibers (fibers may not be visible and remain in air for a long time)

• Asbestos is a hazard ONLY if it can release fibers (friable)

• Friable – pipe insulation, fireproofing, etc.• Non-friable - floor tile, transite (unless machined

or broken)


Damage or Deterioration

• Water leaks, cutting or bumping, strong air currents, age

• Evidence– Debris– Ripped or cracked– Delamination

• Report to ES&H Group immediately


Don’ts

• Don’t use pipes lined with asbestos as a platform to work from

• Don’t cut through pipe insulation

• Don’t bump into sprayed on materials

• Don’t open up enclosures

• Don’t disturb non-friable material

• Don’t clean-up or repair material


OSHA Regulations1910.1001 and 1926.1101

• Presumed Asbestos Containing Material (PACM)

• Determine presence, location, and quantity

• Maintain records

• Warning signs and labels

• Contractor Notification

• Training


Presumed Asbestos Containing Material

• Suspect thermal system insulation, sprayed-on and troweled-on surfacing materials in a building constructed no later than 1980.

• Asphalt and vinyl flooring installed no later than 1980 must be treated as asbestos containing.


Declassification of PACM

• Complete an inspection per EPA requirements

• Accredited inspector or certified industrial hygienist (IH). The State of Illinois requires a license.

• Accredited laboratory• Floor tile and mastic determination of IH

using recognized analytical techniques


Inventory

Building and facility owners shall determine the presence, location and quantity of ACM

and PACM


Fermilab Program (FESHM 5052.4) Inventory

• Inventory – ES&H Share Volume – IH Folder – Asbestos Folder – Inventory

• Buildings built on or before 1980• Thermal System Insulation, Surfacing Materials,

Floor Tile• Materials grouped into “homogeneous areas”• Positive result – one sample in the homogeneous

group (1% or more)


Examples – Friable Material LocationsThermal System

Insulation• Lab A• PS-4• IB2• Wilson Hall Ground Floor

and Below• CUB and tunnel• Transfer Gallery• Cross Gallery• Linac• Site 68

Surfacing Material

• Lab A (enclosed)

• Cross Gallery

• Linac Gallery

• Transfer Gallery


Warning Labels

• Labels must be affixed so that employees will be notified of what materials contain ACM and/or PACM

• Materials not friable (in any foreseeable use, handling, storage, disposal, processing, or transportation) need not be labeled


Warning Signs

Warning signs shall be at the entrance to mechanical rooms/areas in which, if followed, will ensure that ACM and/or PACM will not be disturbed


Training

• Removal Workers

• Operations and Maintenance Workers

• Annual Awareness training for employees “who perform housekeeping operations in an area which contains ACM or PACM


Contractor Notification

• Shall notify of the presence, location and quantity of ACM or PACM at the work site.

• Notification shall be in writing or shall consist or personal communication between the owner and contractor


Procedures

• In building built before, assume all pipe insulation, surfacing material, and floor tile DO contain asbestos whether or not labeled.

• Check inventory database• Contact ES&H Group personnel• May request that the material be sampled• Contact ES&H Group for help if material must be

removed. This can ONLY be done by specially trained individuals.


Review

• Asbestos is a naturally occurring mineral fiber

• It is contained in many materials in buildings built before 1980

• It is associated with asbestosis and lung cancer

• Exposure can occur if friable building material has been damaged

• Exposure can occur if non-friable material sanded, sawed, etc.

• Damage can occur by bumping or cutting, water damage, or deterioration with age


Review

• Inventory

• Label

• Only trained inspectors may take samples

• ES&H Group personnel

• Only trained workers may disturb this material
