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
ES&H SectionFermilab Asbestos Awareness
Asbestos
• Group of Naturally Occurring Minerals
• Fibrous Structure
• Different Types
• Most Common (95%)– Chrysotile (White)– Amosite (Brown)
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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)
ES&H SectionFermilab Asbestos Awareness
Damage or Deterioration
• Water leaks, cutting or bumping, strong air currents, age
• Evidence– Debris– Ripped or cracked– Delamination
• Report to ES&H Group immediately
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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.
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
Inventory
Building and facility owners shall determine the presence, location and quantity of ACM
and PACM
ES&H SectionFermilab Asbestos Awareness
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)
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
Training
• Removal Workers
• Operations and Maintenance Workers
• Annual Awareness training for employees “who perform housekeeping operations in an area which contains ACM or PACM
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
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
ES&H SectionFermilab Asbestos Awareness
Review
• Inventory
• Label
• Only trained inspectors may take samples
• ES&H Group personnel
• Only trained workers may disturb this material
