objectives
Objectives
  • Describe the properties of asbestos.
  • Describe the health effects from exposure.
  • Recognize asbestos hazards and practice effective control measures

importance of training
Importance of Training
  • Asbestos containing material (ACM) is found in buildings and work areas where workers may come into contact with it.
  • Asbestos is potentially hazardous to health.
  • Exposure to asbestos is governed by federal and state regulations.
properties of asbestos
Properties of Asbestos
  • Naturally occurring fibrous mineral consisting of complex silicates
  • Virtually indestructible because
    • Fibers are resistant to heat, cold, and chemicals
    • Fibers are not water soluble and remain in the air
  • Fibers can be densely packed to make a tough, flexible material for insulation and other industrial uses
properties of asbestos1
Properties of Asbestos

Individual fibers are microscopic in size; some may be up to 700 times smaller than a human hair

definition of terms
Definition of Terms
  • ACM: Asbestos-containing material containing more than 1% asbestos
  • PACM: Presumed asbestos-containing material; thermal system insulation and surfacing material found in buildings constructed prior to1980
  • Surfacing material: Material that is sprayed, troweled-on or otherwise applied to surfaces
  • Thermal system insulation (TSI) ACM applied to pipes, fittings, boilers, tanks, ducts, or other structural components to prevent heat loss or gain and contains more than 1% asbestos.

29 CFR 1910.1001 (b)

types of asbestos
Types of Asbestos
  • Chrysotile (white) — used in insulation, fire- and sound-proofing, surfacing materials, adhesives
  • Amosite (brown) — used in high friction applications; brake shoes, clutches, and other equipment
  • Crocidolite (blue) — not as common as the other two forms; high-temperature applications such as gaskets
potential asbestos locations
Potential Asbestos Locations
  • Thermal system insulation (TSI) on furnaces, ducts, boilers, and water pipes
  • Sprayed-on or troweled-on surfacing materials
  • Asphalt and vinyl flooring and mastics
  • Suspended ceiling tiles

  • Fireproofing on metal beams & columns
  • Gypsum blocks used in older wall construction
  • High temperature gaskets and packing in valve stems

when is asbestos a hazard
When Is Asbestos a Hazard?
  • ACM becomes hazardous when its bonding material breaks down and it becomes friable.
  • Friable ACMs can easily be crushed or crumbled by hand pressure releasing fibers into the air.
when is asbestos a hazard1
When Is Asbestos a Hazard?
  • TSI and surfacing ACM are potentially friable.
  • ANY activity involving ACM is capable of releasing hazardous fibers.
  • Assume that dust or debris contains asbestos fibers when friable ACM is in the vicinity.
potential high risk areas
Potential High Risk Areas
  • A work area that contains friable asbestos
  • A work area that is near construction or renovations that contain asbestos
  • Maintenance or custodial activities in work areas containing asbestos

Report any deterioration of ACM to your supervisor!

when is asbestos safe
When Is Asbestos Safe?
  • It is safe to work in areas with non-friable ACM.
  • The fibers in non-friable ACM are tightly bonded and won’t be released unless disturbed or damaged in some way.
health effects1
Health Effects
  • Asbestos fibers are dangerous when inhaled because they cannot be broken down and in time damage the lungs.
  • Symptoms may take 15 to 30 years or more to develop.
  • The long-term effects of asbestos exposure can result in:
    • Asbestosis
    • Lung cancer
    • Mesothelioma
asbestosis
Asbestosis
  • Asbestosis is a chronic, non-cancerous respiratory disease in which inhaled asbestos fibers cause lung tissues to scar.
  • Scar tissue is not able to transfer oxygen so as scarring increases, lung function decreases
  • Symptoms are fatigue, shortness of breath, and a dry crackling sound when inhaling.
lung cancer
Lung Cancer
  • Causes the largest number of deaths related to asbestos exposure
  • Common symptoms include:
    • Shortness of breath
    • Coughing up blood
    • Fatigue
    • Persistent chest pains
    • Weight loss
    • Anemia
mesothelioma
Mesothelioma
  • Rare form of cancer occurring in the membrane (mesothelium) which lines the lungs, chest, abdomen, and the pericardium (heart sac)
  • Symptoms include fatigue, chest pain, weight loss
  • Very invasive although it may take years to develop
  • Is painful and always fatal.
asbestos exposure and smoking
Asbestos Exposure and Smoking
  • Smoking combined with asbestos exposure increases the risk of asbestosis and lung cancer.
  • Asbestos workers who smoke are 60-90 times more likely to develop lung cancer than those who don’t smoke nor have been exposed to asbestos.
  • Quitting smoking reduces the risk of lung cancer by 50% in just five years.
employer responsibility
Employer Responsibility
  • Provide asbestos awareness training for employees working near ACM or PACM
  • Provide notification of exposure risks
  • Post warning signs on known ACM and entrances to asbestos work areas
  • Materials suspected to contain asbestos must be tested before they are disturbed (BP ASH page 21).
  • Only trained workers may sample and remove asbestos-containing materials. (BP ASH page 21).
employee responsibility
Employee Responsibility
  • Follow safety procedures
  • Be alert to the presence of warning signs/labels
  • Report any disturbances or damage to ACM or PACM

controlling exposure
Controlling Exposure

DO NOT:

  • Drill holes or hammer nails in ceiling or walls with ACM or PACM.
  • Remove ceiling tiles or light fixtures from suspended ceiling grids.
  • Cut through pipe insulation.
  • Scrape floor tiles, walls or ductwork.
  • Dust, sweep or vacuum up debris that may contain asbestos.
  • Hang plants from insulated pipes.

reporting procedure
Reporting Procedure

If you find disturbed material, not previously marked, that you SUSPECT may contain asbestos, notify your supervisor or your Safety/Industrial Hygiene Representative.
