Course Number: NSTC-18 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC-18 7 What Is Asbestos?

© North Slope Training Cooperativerevised 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

© North Slope Training Cooperativerevised 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

Course Number: NSTC 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.

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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.

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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.

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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!

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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 wont be released unless disturbed or damaged in some way.

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC Health Effects

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC Asbestos Exposure and Smoking Smoking combined with asbestos exposure increases the risk of asbestosis and lung cancer. Asbestos workers who smoke are times more likely to develop lung cancer than those who dont smoke nor have been exposed to asbestos. Quitting smoking reduces the risk of lung cancer by 50% in just five years.

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC Control Measures

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC Follow safety procedures Be alert to the presence of warning signs/labels Report any disturbances or damage to ACM or PACM Employee Responsibility Damaged asbestos- containing drywall

© North Slope Training Cooperativerevised All rights reserved. Course Number: NSTC 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. Controlling Exposure ASH, page 159; BP ASH, page 202

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