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

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


Fibrous – can be used in a variety of ways

Good Things About Asbestos
uses prior to 1980
Ceiling tiles

Drywall taping compound

Adhesives and mastics

Thermal system insulation

Roofing felts


Vibration dampers

Cement sheet (transite)

Floor tile

Valve packing and insulation

Fire Resistant drywall

Sprayed-on fireproofing

Uses – Prior to 1980
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

Health Concerns
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

How Much Is Too Much?
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)

So What?
damage or deterioration
Water leaks, cutting or bumping, strong air currents, age



Ripped or cracked


Report to ES&H Group immediately

Damage or Deterioration
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 regulations 1910 1001 and 1926 1101
Presumed Asbestos Containing Material (PACM)

Determine presence, location, and quantity

Maintain records

Warning signs and labels

Contractor Notification


OSHA Regulations1910.1001 and 1926.1101
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.

Presumed Asbestos Containing Material
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

Examples – Friable Material Locations
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 Labels
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 disturbedWarning Signs
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

Contractor Notification
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.

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



Only trained inspectors may take samples

ES&H Group personnel

Only trained workers may disturb this material
