ASBESTOSASBESTOSAwareness for Awareness for Operations and Operations and

MaintenanceMaintenance

Introduction Prior to 1980, asbestos was added to a

variety of products to strengthen them and provide heat insulation and fire resistance. In most products, asbestos is combined with a binding material so that it is not readily released into the air.

Objectives This training module will provide you with

information to increase your awareness of asbestos-containing material; completion of this training will not permit you to work directly with asbestos-containing material.

Important DefinitionsImportant Definitions

“Asbestos” includes chrysotile, amosite, crocidolite, tremolite asbestos, anthophyllite asbestos, actinolite

“Asbestos-Containing Material (ACM)” means any material containing more than 1% asbestos.

“Authorized person” means any person authorized by the employer and required by work duties to be present in regulated areas.

“Employee exposure” means that exposure to airborne asbestos that would occur if the employee were not using respiratory protective equipment.

“Fiber” means a particulate form of asbestos 5 micrometers or longer, with a length-to-diameter ratio of at least 3 to 1.

“Friable” means ACM that can be crushed, broken, or otherwise damaged using ones hands, potentially releasing asbestos fibers to the air.

Important DefinitionsImportant Definitions

“High-Efficiency Particulate Air (HEPA) filter” means a filter capable of trapping and retaining at least 99.97 percent of 0.3 micrometer diameter mono-disperse particles.

“Presumed Asbestos Containing Material (PACM)” means thermal system insulation and surfacing material found in buildings constructed no later than 1980.

“Regulated area” means an area established by the employer to demarcate areas where airborne concentrations of asbestos exceed, or there is a reasonable possibility they may exceed, the permissible exposure limits.

“Surfacing material” means material that is 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).

“Thermal System Insulation (TSI)” means ACM applied to pipes, fittings, boilers, breeching, tanks, ducts or other structural components to prevent heat loss or gain.

What Is Asbestos?What Is Asbestos?

Naturally occurring mineral

Three primary forms:

Chrysotile,

Amosite, and

Crocidolite

Over 3,000 different building products could contain asbestos

Desirable physical properties (thermal stability, etc.)

Asbestos Containing Materials (ACM) contain >1% asbestos

Laboratory analysis can be used to verify presence of asbestos

Categories of ACM Categories of ACM Used in BuildingsUsed in Buildings

Surfacing Materials -- ACM sprayed or troweled on surfaces (walls, ceilings, structural members) for acoustical, decorative, or fireproofing purposes. This includes plaster and fireproofing insulation.

Thermal System Insulation (TSI) -- Insulation used to inhibit heat transfer or prevent condensation on pipes, boilers, tanks, ducts, and various other components of hot and cold water systems and heating, ventilation, and air conditioning (HVAC) systems. This includes pipe lagging, pipe wrap; block, batt, and blanket insulation; cements and "muds"; and a variety of other products such as gaskets and ropes.

Miscellaneous Materials -- Other, largely nonfriable products and materials such as floor tile, ceiling tile, roofing felt, concrete pipe, outdoor siding, and fabrics.

Abatement ActivitiesAbatement Activities

Encapsulation (or sealing) involves coating materials so that asbestos is sealed in.

Enclosure involves placing something over or around the material that contains asbestos to prevent release of fibers.

Removal involves physically removing the asbestos and may only be done by a contractor with special training and licensing

Abatement ActivitiesAbatement Activities

Prior to any repairs, renovations, constructions, or demolitions that might contact or damage ACM, the following must be addressed: Survey to Identify ACM Project Designer Occupant Notification Work Area Containment Posting of Work Areas Engineering Controls PPE Air Monitoring Accredited Contractor OCC Oversight of Contractor

When Is Asbestos A Risk To When Is Asbestos A Risk To Health ?Health ?

Consider the type of product. How well is the asbestos bonded into it? Is it likely to contain a small or large

amount of asbestos ?

And, consider the condition; Good? Is it intact, sealed, painted? Damaged? What is the extent of

damage?

What are the Potential What are the Potential Health Effects?Health Effects?

If asbestos is disturbed and inhaled it could cause: Asbestosis Lung Cancer (Mesothelioma) Other Chronic Health Effects, such as respiratory

irritation or aggravation of existing respiratory ailments (i.e. asthma)

The greater the exposure, the greater the risk of developing an asbestos-related disease. The amount of time between exposure to asbestos and the first signs of disease can be as much as 30 years.

Defense MechanismsDefense Mechanisms

Nose and mouth• Asbestos becomes trapped on surface tissues or in

saliva/mucous• Swallowed or otherwise removed from the respiratory

system Mucous-lined breathing passages

• Asbestos becomes trapped in mucous• Removed from respiratory system via normal mucosal

movement Cilia (tiny hair-like structures) in the lungs

• Asbestos trapped on outer surface of cilia (mucous)• Transported out of lungs via movement of the cilia and

removed from respiratory system

SmokingSmoking

Impairs body’s defense mechanisms

Significantly increases risk of lung cancer

Prohibited ActivitiesProhibited Activities

DO NOT Drill holes in ACM Hang plants or anything else from ACM

ceilings or coated piping Hang pictures on ACM walls Sand or dry-buff ACM floor tiles Damage ACM when moving furniture,

replacing light bulbs, cleaning, etc.

EMERGENCY PROCEDURESEMERGENCY PROCEDURES
