6
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.
Importance of Training

7
What Is Asbestos?
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
8
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 Asbestos
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
9
Individual fibers are microscopic in size; some may be up to 700 times smaller than a human hair
Properties of Asbestos

10
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.

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.

18
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.

19
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
Potential High Risk Areas
Report any deterioration of ACM to your supervisor!

20When 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 Effects
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
22
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
Health Effects
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
23
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.
Asbestosis
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
24
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
Lung Cancer
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
25
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.
Mesothelioma

26
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.

Control Measures
© 1997-2010 North Slope Training Cooperative—revised 2010. All rights reserved. Course Number: NSTC-18
28
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).
Employer Responsibility

Report any disturbances or damage to ACM or PACM
Employee Responsibility

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.
