1 ASBESTOS AWARENESS

2 THREE OSHA REGULATIONS PERTAIN TO PONTENTIAL WORKPLACE EXPOSURES TO ASBESTOS 29 CFR –Applies to construction, demolition, abatement and maintenance activities in any structure or building. In general, most activities that may intentionally disturb asbestos fibers are governed by this standard. 29 CFR –Applies to all maritime or ship related asbestos activities. 29 CFR –Applies to all other potential occupational exposures to asbestos, that may result in contact, which does not disturb the asbestos. Some of these activities include: –Housekeeping such as cleaning asbestos containing or presumed asbestos containing building materials such as flooring or walls – Repairing or replacing automotive brakes and clutches –Manufacturing of asbestos containing products.

3 –ASBESTOS AWARENESS TRAINING is a provision of the general industry standard 29 CFR that requires “asbestos awareness training” for employees who perform housekeeping operations in an area that contains ACM or PACM. Asbestos awareness may also be suitable for other individuals who work around, but do not disturb, ACM or PACM, as well as individuals who need to be informed about asbestos related work activities that may be conducted by others in their work area.

4 ACRONYMS ACM –Asbestos containing material PACM –Presumed asbestos containing material

5 OBJECTIVES 1.Explain the potential health effects of long-term exposure to airborne asbestos fibers. 2.Define the term “friable” as it pertains to asbestos. 3.Describe several potential locations within the facility where asbestos containing materials may be present. 4.Explain what to do if asbestos fibers are released. 5.Describe several specific housekeeping procedures to follow when the work involves asbestos. 6.Describe the five general workplace protective measures that are employed during asbestos related work activities.

6 PROGRAM OUTLINE 1.THE NATURE OF ASBESTOS –A. Bonded and friable asbestos –B. Identification 1. Can’t be done visually 2. Bulk sampling 2.HEALTH EFFECTS –A. Natural defense mechanisms –B. Asbestos related diseases 1. Asbestosis 2. Pleural disease 3. Lung cancer 4. Mesothelioma –C. Smoking and asbestos

7 3.LOCATIONS OF ABESTOS –A. Fireproofing –B. Thermal insulation –C. Boilers –D. Building ventilation systems –E. Ceiling tiles –F. Dry wall, dry wall tape or plaster –G. Textured paints –H. Roofing shingles, felt, tar and flashing –I. Decorative building materials - textured paints –J. Sheathing on electronics and power cables –k. Transite (corrugated looking materials, cement texture - not fiberglass - not aluminum) –L. Pads found in automotive brakes and clutches.

8 4.WHAT TO DO IF ASBESTOS IS DISTURBED –A. Do not continue the work activity –B. Do not allow others into the area –C. Do not modify the suspected asbestos containing material –D. Do not clean up any debris that may include suspected asbestos containing material –E. Alert your supervisor. 5.HOUSEKEEPING PROCEDURES –A. Don’t remove ACM unless properly trained and all procedures are followed –B. Keep surfaces free of asbestos dust and debris –C. Use HEPA filtered vacuums for asbestos cleanup –D. Use wet methods –E. Use low speed floor buffers –F. Dispose of all asbestos contaminated materials according to governmental requirements. Contact Environmental.

9 6.GENERAL PROTECTIVE MEASURE –A. Identification –B. Isolation –C. Monitoring –D. Special work practices –E. Clean-up of the work area – (CAUTION: Remember, cleanup or removal of asbestos can only be done by qualified contractors). 7.WARNING - CAUTION - NOTE –Asbestos containing materials in good condition do not pose a health hazard, nor does EPA recommend the removal of ACM in good condition. Do not initiate self-help, or any renovation / demolition work that may involve building materials that are known or suspected of containing asbestos without coordination with Environmental.

10 POINTS FOR REVIEW 1.What is asbestos Asbestos is a naturally occurring mineral that has been used for hundreds of years as an insulation and fireproofing material. 2.Is bonded or covered asbestos a health hazard ? Asbestos that is bonded, coated, covered or otherwise protected so that no fibers can become airborne doesn’t present a hazard. 3.What is “friable” Asbestos ? Friable asbestos is asbestos that may be crumbled, pulverized or reduced to powder by hand pressure when dry. Friable asbestos has the potential to release asbestos fibers that can become airborne.

11 4. Can asbestos be identified visually ? There is no way to visually identify asbestos. Many materials that contain asbestos look just the same as materials that don’t. 5. How can you identify asbestos containing materials ? The only way to be sure is to have representative samples of the material, called bulk samples, analyzed in a laboratory.

12 ASBESTOSIS PLEURAL DISEASE LUNG CANCER MESOTHELIOMA 6. What are some of the health effects that could result from exposure to airborne asbestos fibers ? * Asbestosis - a progressive, non-cancerous and irreversible scarring of the lungs that can produce shortness of breath.. * Pleural disease - plaque deposits or a thickening of the thin tissue that separates the lungs from the other organs in the body. * Lung cancer - cancerous tumors that have a latency period of 20 to 30 years. Lung cancer is usually fatal. * Mesothelioma - a cancer in the lining of the chest cavity or abdomen. Mesothelioma is always fatal.

13 7.How does smoking relate to asbestos exposure ? Research has shown that smoking significantly increases the risk of lung cancer in individuals who are exposed to asbestos. Tobacco smoke interacts with the asbestos increasing the damaging effects on the body’s lung tissue. A person who smokes 2 packs a day and is exposed to asbestos is 100 times more susceptible to lung cancer than a non- smoker with no asbestos exposure.

14 8.What are some of the typical locations where asbestos may be found in the workplace ?

15 9.What are some of the locations within a home where asbestos can be found ? shingles, wall boards, tile, piping

16 10.What should you do if you suspect that asbestos containing material may be present and that your work activity may disturb the material ? Stop what you are doing Do not allow others into the area Do not modify the suspected asbestos containing material Do not try to clean up any debris that may include suspected asbestos containing material Alert your supervisor that you may have encountered suspected asbestos containing material. (Supervisor must immediately contact Environmental)

17 11.Important housekeeping procedures that relate to asbestos containing material. Don’t remove any asbestos containing material unless you have received adequate training and all appropriate work practices are followed. All surfaces should be kept as free as possible of asbestos dust, debris and waste. Use a High Efficiency Particulate Air (HEPA) filtered vacuum for any clean- up of asbestos contaminated material. Use wet methods to prevent dust release whenever possible. Use low speed floor buffers (less than 300 RPM) with low abrasion pads when cleaning or stripping asbestos containing floor material. (OSHA Class 4 janitorial) Dispose of all asbestos contaminated materials in properly labeled impermeable bags or containers according to governmental requirements.

18 12.General workplace protective measures that are employed during asbestos related work activities. Identification - including bulk sampling and laboratory analysis when necessary. Isolation - including restricting access and erecting enclosures when needed. Monitoring of the isolation, work and clean-up to verify that the engineering controls are working properly and that no asbestos fibers have escaped the enclosure. (NOTE: This is done by BIO-) Special work practices including using proper personal protective equipment and, where appropriate, negative pressure within the work area to prevent fiber release.

19 –Protect your self from the hazards of asbestos Understand the possible risk Follow policies and procedures and Do not disturb, Ask if you have any concerns.

20 Quicksilver Policy Activities that require the transporting, removal, handling, and/or disposal of asbestos containing material shall be performed by qualified asbestos removal contractors only!
