6 What is Asbestos? Asbestos is a fibrous mineral that is naturally occurring in our environment. Significant asbestos deposits are found and mined in Canada and South Africa. Because asbestos is a recognized health hazard, those individuals who work near asbestos have to know it s health effects and how to work safely around it. 6

7 Types of Asbestos There are six different types of asbestos. These include: Amosite Actinolite Chrysotile Anthophyllite Tremolite Crocidolite 7

8 Three Most Common Types The three most common types are: Chrysotile (white) Amosite (brown / off white) Crocidolite (blue) Raw mineral photograph - Chrysotile. 8

9 Why Use Asbestos? Naturally occurring fibrous minerals Good tensile strength Flexible Heat resistant Electrical resistance Good insulation Chemical resistant Washington State Department of Labor and Industries Division of Safety and Health (DOSH) 9

10 Asbestos is a Fibrous Material By nature, asbestos is a fibrous material: Asbestos tends to break into very tiny fibers. The only recognized method to identify asbestos fibers is through the use of a microscope. Some asbestos fibers may be up to 700 times smaller than a human hair. 10

11 Asbestos is Light in Weight Asbestos fibers are also very light in weight. Their size and weight makes it easy for asbestos to stay suspended in air for a long period of time, sometimes for days. 11

12 Asbestos Is Commonly Mixed With Other Components Asbestos is commonly mixed with other components to make a marketable product. Some floor tiles, for example, contain only a small percentage of asbestos. The amount of asbestos in Asbestos Containing Materials (ACM) in any product can vary from 1 100%. 12

13 Asbestos Is Typically Found In: Surfacing Treatments: Fireproofing Acoustical Plaster Finish Plasters Skim Coats of Joint Compound Sprayed on fire proofing. 13

14 Asbestos Is Typically Found In: Thermal System Insulation (TSI): Equipment Insulation Boiler, Breeching, Duct, or Tank Insulation, Cement or Mortar Used for Boilers and Refractory Brick Piping and Fitting Insulations including but not limited to, Wrapped Paper, Aircell, Millboard, Rope, Cork, Preformed Plaster, Job Molded Plaster and coverings over fibrous glass insulation 14

15 Asbestos Is Typically Found In: Roofing and Siding Miscellaneous Materials: Insulation Board Vapor Barriers Coatings Non Metallic or Non Wood Roof Decking, Felts, Cementitious Board (Transite) Flashing Shingles Galbestos Roof shingles made with asbestos. 15

16 Asbestos Can Also Be Found In: Other Miscellaneous Materials: Dust and Debris Floor Tile Cove Base Floor Leveler Compound Ceiling Tile Vermiculite Insulation Gaskets, Seals, Sealants (including for condensate control) 16

17 Asbestos Can Also Be Found In: Other Miscellaneous Materials: Vibration Isolators Laboratory Tables and Hoods Chalkboards Pipe Penetration Packing or other Fire Stopping Materials Cementitious Pipe (Transite) Cementitious Board (Transite) Electrical Wire Insulation 17

18 Additional Miscellaneous Materials: Other Miscellaneous Materials: Electrical Wire Insulation Fire Curtains Fire Blankets Fire Doors Brakes and Clutches Mastics, Adhesives and Glues Caulks Sheet Flooring (Linoleum) 18

19 Additional Miscellaneous Materials: Other Miscellaneous Materials: Wallpaper Drywall Plasterboard Spackling/Joint Compound Textured Paint Grout Glazing Compound and Terrazzo Boiler Rope 19

20 Danger Signs will be posted in buildings that have asbestos containing materials in them acknowledging the presence of the material hazard.

21 Danger Asbestos containing pipe and boiler insulation will be labeled with identifying markings, signs, and stickers. 21

22 Note: Ceiling or floor tiles containing asbestos will not be labeled or marked. ANY samples must be taken by a Certified Technician An Accredited Lab must conduct the analysis of the material for asbestos content. 22

23 ACTIVITY: Where Is It Field Trip! We have arranged to tour an area in this facility to identify those locations where asbestos may have been previously located. Using the lists from the Participant Guide pages six through eight as a reference, write down the locations and describe what you see. We will discuss these as we proceed through the area! 23

24 ! Remember Asbestos Can Be Dangerous! 24

25 Asbestos Banning Countries There are currently 55 countries that have banned asbestos including the United Kingdom, Australia, parts of Africa and South America, as well as several countries across Europe. Some of these 55 countries are either phasing out asbestos entirely or allowing for minor use in special circumstances. The United States, Canada, Brazil, China, Russia, and India have not banned asbestos. EPA.gov 25

26 USA Banned Asbestos- Containing Products Under the Consumer Product Safety Act (Consumer Product Safety Commission): Banned Products (1977) Artificial Fireplace Embers and Wall Patching Compounds EPA.gov 26

27 USA Banned Asbestos Containing Products Continued Under the Clean Air Act (CAA): Banned Asbestos containing Uses (1978) Asbestos pipe insulation and asbestos block insulation on facility components, such as boilers and hot water tanks, if the materials are either pre formed (molded) and friable or wet applied and friable after drying. Spray applied surfacing asbestos containing materials Spray on application of materials containing more than 1% asbestos to buildings, structures, pipes, and conduits unless certain conditions specified under 40 CFR 61, Subpart M are met. EPA.gov 27

28 USA Banned Asbestos Containing Products Continued Under the Toxic Substances Control Act (TSCA): Banned Manufacture, Importation, Processing and Distribution in Commerce of Certain Asbestos containing Products (1989) Corrugated paper Roll board Commercial paper Specialty paper Flooring felt EPA.gov 28

29 Inhalation of Asbestos The most common way for asbestos fibers to enter the body is through breathing (inhalation). When Asbestos Containing Materials (ACM) can be easily crushed by hand, the materials are said to be friable. 29

30 When Is Asbestos Dangerous? Asbestos is most hazardous when it is friable. As examples: Sprayed on asbestos insulation and ceiling tiles are highly friable. Asbestos floor tile is not. 30

31 Pipe and Boiler insulation There is not as much of a hazard in Asbestos pipe and boiler insulation unless the covering is cut or damaged in such a way that the asbestos underneath is actually exposed to the air. 31

32 What are the Health Effects? The human body cannot break down or eliminate asbestos fibers after they enter the body. Once in place, they contribute to the development of diseases, including: Asbestosis Lung Cancer Mesothelioma 32

33 Health Effects: Asbestosis Asbestosis is caused by the deposition of fibers in the lung passageways (bronchi). This respiratory disease can result in massive scarring of the lung tissue. In turn, this scarring limits the ability for the lung to expand (breathe). 33

34 Health Effects: Asbestosis Health effects include shortness of breath, cough, fatigue, fluid in the lungs, heart stress, and possibly death. There is no effective treatment for asbestosis; the disease is usually disabling or fatal. Indications of having the disease (latency period) is typically 1 20 years after the initial exposure. 34

35 Health Effects: Lung Cancer Lung cancer constitutes the greatest health risks for workers who are exposed to asbestos: Lung cancer is related to over half of the deaths attributed to asbestos exposure. Asbestos fibers alter lung cells disturbing the regulation of cell growth. Common symptoms of lung cancer are coughing, shortness of breath, chest pain, fatigue, loss of appetite and weight loss. 35

36 Health Effects: Lung Cancer Asbestos induced Lung Cancer is rarely curable: Most individuals will die within 5 years of diagnosis. Causes can include brief peak exposures or long term low exposures Cigarette smoking greatly increases the chances of contracting asbestos related lung cancer. 36

37 Health Effects: Mesothelioma Mesothelioma, cancers affecting the lining of the lung, heart, and abdomen, are extremely rare in persons without prior exposure to asbestos. Latency period is typically years. Survival rates in excess of 1 year are non existent. 37

38 Health Effects: Mesothelioma Symptoms: Cancer of the Lining of the Lung Chest pain, fluid in the chest cavity, shortness of breath, loss of appetite and weight, fever, hoarseness. Symptoms: Cancer of the Lining of the Abdomen Pain and swelling of the abdomen, nausea, bowel and urinary obstructions, swelling, hernia. Mesothelioma can be triggered by extremely low exposures, even secondary ones!!! 38

39 Health Effects: Other Cancers Cancers of the esophagus, stomach, colon, rectum, larynx, pharynx, and buccal cavity occur at increased rates in people exposed to asbestos. 39

40 What Increases The Chances Of Developing Diseases? Things that seem to determine your likelihood of developing one of these asbestos related diseases: 1. The amount and duration of exposure. 40

41 What Increases The Chances Of Developing Diseases? 2. Smoking there is a definite proven relationship between smoking and asbestos exposure causing the increased risk of developing cancer. Lung cancer death rates for smoking asbestos workers are up to 53.2 times more than for those who don t smoke and are not exposed to asbestos. 41

42 What Increases The Chances Of Developing Diseases? 3. Age Mesothelioma can occur at any age. Secondary chronic exposures (e.g. exposures that occur when an asbestos handler brings home asbestos dust home on his/her clothes) that happen over a short period have been known to result in mesothelioma to people of any age. 42

43 OSHA and NYS Regulations OSHA Regulations 29CFR Asbestos Construction Regulations. Covers construction work, including alteration, repair, renovation, and demolition of structures containing asbestos. 43

44 OSHA and NYS Regulations OSHA Regulations 29CFR Asbestos General Industry Regulations. Applies to asbestos exposure in general industry, such as exposure during brake and clutch repair, custodial work, and the manufacture of asbestoscontaining products 44

49 OSHA and NYS Regulations New York State 12 NYCRR Part 56 NYS Code Rule 56 Asbestos Subpart 56 4: General Project Air Sampling & Lab Analysis Requirements Qualifications of Air Sampling Personnel Laboratory Certification Independent Third Party Sampling and Analysis How are air or bulk (material) samples analyzed? 49

50 OSHA and NYS Regulations New York State 12 NYCRR Part 56 NYS Code Rule 56 Asbestos Are there any questions about the intent and applicability of Code Rule 56? 50

51 Working Safely Around Asbestos If you any have reason to suspect that something is asbestos containing... Do Not Disturb it!!! Do you remember from Code Rule 56 what is considered to be Presumed or Suspect Miscellaneous Asbestos Containing Material (ACM)? 51

52 Working Safely Around Asbestos You must always assume that materials are asbestos containing, unless it is proven otherwise! How do you prove that something is not asbestos containing? 52

53 Working Safely Around Asbestos As stated in the NYS Code Rule 56 Materials need to be sampled by certified technicians. Samples need to be sent to a NYS certified lab for analysis. Removal needs to be performed by Certified Abatement Firms and Certified Abatement Workers. 53

54 Working Safely Around Asbestos Have a Questioning Attitude! Figure out where in your workplace Asbestos Containing Materials (ACM) will most likely be located. Avoid disturbing ACM. If you are not absolutely sure ask someone! 54
