introduction
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
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.
training requirements
Training Requirements
  • Awareness Training
    • Asbestos-Uses and Forms
    • Location of Asbestos Containing Materials (ACM) and Presumed Asbestos Containing Materials (PACM)
    • Recognition of Damage
    • Names and Telephone Numbers of Program Manager and Emergency Personnel
    • Additional training may be necessary for personnel with certain duties
rules and regulations
Rules And Regulations
  • Occupational Safety and Health Administration (OSHA)
  • Environmental Protection Agency (EPA)
  • OCC Asbestos Operations and Maintenance Program
important definitions
Important 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 definitions1
Important 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
where is asbestos often found
Where is Asbestos Often Found?
  • Pipe and duct insulation
  • Building insulation
  • Wall and ceiling panels
  • Carpet underlays
  • Roofing materials
  • Artificial fireplaces and materials
  • Patching and spackling compounds
  • Brake pads and linings
  • Pot holders and ironing board pads
  • Hair dryers
  • Floor tiles
  • Electrical wires
  • Textured paints
  • Cements
  • Toasters and other household appliances
  • Furnaces and other furnace door gaskets
categories of acm used in buildings
Categories of ACM Used 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 activities
Abatement 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 activities1
Abatement 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 health
When Is Asbestos A Risk To 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 health effects
What are the Potential 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 mechanisms
Defense 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
smoking
Smoking
  • Impairs body’s defense mechanisms
  • Significantly increases risk of lung cancer
prohibited activities
Prohibited 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 procedures
EMERGENCY PROCEDURES
  • Major fiber release
    • Stop work immediately
    • Do not attempt clean-up
    • Secure area
    • Notify supervisor
    • Contact the campus Chief Engineer
    • Do not reenter area until instructed to do so
