1 LEAD HAZARDS AND ASBESTOS AWARENESS TRAINING E LIGHT ELECTRIC SERVICES E LIGHT WIND AND SOLAR August 3, 2010 E Light Electric Services

2 OBJECTIVE Prevent lead intoxication and related injuries during the use, handling, removal, and melting of materials containing lead. August 3, 2010 E Light Electric Services

3 WHAT IS LEAD? Lead is metallic lead, all inorganic lead compounds, and organic lead soaps. Some of the properties of lead that make it a useful structural material are: Low melting point Very abundant High molecular weight High density Very malleable (easy to shape) August 3, 2010 E Light Electric Services

4 HOW LEAD GETS INTO THE BODY Inhalation (breathing) Ingestion (by mouth) Lead is usually not absorbed through the skin Once lead enters the body, it enters your bloodstream and is circulated throughout your body. This lead then becomes stored in various organs of the body. If you continue to be exposed to lead, you will begin to store more than your body can get rid of and you will begin to suffer the symptoms of lead poisoning. August 3, 2010 E Light Electric Services

5 COMMON USES FOR LEAD Batteries Ballast Weights Radiation shielding Roof flashings Paint filler Pipe joints Acoustic insulation Ammunition Solder Rubber anti-oxidant Cable shielding August 3, 2010 E Light Electric Services

6 LEAD EXPOSURE OPERATIONS Lead and Babbitt melting and casting Ballast handling Grinding, sanding material that contains lead Soldering with torches Lead-acid battery reclaiming Machining lead Contact with contaminated clothing Removal of lead-based paints August 3, 2010 E Light Electric Services

7 HEALTH HAZARDS Lead interferes with the formation of the hemoglobin in blood and will cause anemia. Lead causes cellular kidney damage which leads to kidney failure. It can cause reduced sperm count and decreased fertility. HEMOGLOBIN ANEMIA DECREASE FERTILITY KIDNEY DAMAGE August 3, 2010 E Light Electric Services

8 HEALTH HAZARDS CONT'D Lead can damage the nervous system, the blood forming organs, kidneys, and reproductive system. Chronic exposure initially damages the blood forming and reproductive organs, and eventually cause peripheral nerve and central nervous system damage. Lead can pass from mother to infant through the placenta. NERVOUS SYSTEM BLOOD FORMING ORGANS CENTRAL NERVOUS SYSTEM REPRODUCTIVE ORGANS August 3, 2010 E Light Electric Services

9 E XCEEDING E XPOSURE L IMITS If Action Level is exceeded, it is necessary to begin air monitoring, employee training, and medical surveillance. Any employee known to have been exposed to airborne concentrations exceeding PEL, shall be notified in writing of the exposure as soon as possible, but not later than 5 days after the finding. NLT 5 DAYS August 3, 2010 E Light Electric Services

10 R EPRODUCTIVE S YSTEM E FFECTS Exposure to lead can have serious effects on the reproductive function of both males and females. In males there can be a decrease in sexual drive, impotence, decreased ability to produce healthy sperm, and sterility. Women may experience menstrual disturbance including Dysmenorrhea (painful menstruation), Menorrhagia (abnormally profuse blood flow), and Amenorrhea (abnormal absence or suppression of menstrual discharge.) August 3, 2010 E Light Electric Services

11 R EPRODUCTIVE S YSTEM E FFECTS (CONT'D ) There is a higher frequency of sterility, premature births, spontaneous miscarriages, and stillbirths. Lead can alter the structure of sperm cells raising the risk of birth defects. Infants with mothers who had lead poisoning have a higher mortality rate during the first year and suffer from lower birth rates, slower growth, and nervous system disorders. August 3, 2010 E Light Electric Services

12 P ERMISSIBLE E XPOSURE L IMITS The permissible exposure limit (PEL) for an 8 hour time weighted average (TWA) exposure to airborne lead is 50 micrograms per cubic meter of air. If an employee is exposed for more than 8 hours in a work day, the PEL shall be determined by the following formula: PEL =____________400________________ Number of work hours per day August 3, 2010 E Light Electric Services

13 A CTION L EVEL The action level (AL) for an 8 hour TWA exposure to airborne lead is 30 microgram/cubic meter of air (without regard to respirator use). Biological monitoring and medical surveillance shall be initiated when an employee's exposure exceeds the action level for more than 30 days per year. ACTION LEVEL August 3, 2010 E Light Electric Services

14 PERMISSIBLE EXPOSURE LIMIT Where any employee is exposed to lead above the PEL, but for 30 days or less per year, the employer shall implement engineering controls to reduce exposures to 200  g/m 3, but thereafter may implement any combination of engineering, work practice, and respiratory controls to reduce and maintain employee exposure to lead to or below 50  g/m 3. August 3, 2010 E Light Electric Services

August 3, 2010 E Light Electric Services

34 MEDICAL SURVEILLANCE PROGRAM Three basic elements: - Pre-placement medical evaluation. All personnel must receive a pre-placement evaluation prior to assignment to a position involving potential exposure to lead that equals or exceeds the action level - Semi-annual blood lead monitoring unless air monitoring indicates exposures above the action level for more than 30 days per year. - Follow-up medical evaluations and blood lead analysis based on the results of blood lead analysis & physician's opinion. August 3, 2010 E Light Electric Services

35 WORKPLACE MONITORING PLAN An Industrial Hygienist must evaluate all workplaces at least annually, or more frequently if necessary, where lead is used and shall reevaluate the operation within 5 working days of any work process or control change. The employee or designated employee representative must be given the opportunity to observe sampling or monitoring. The employer must collect full shift (7 continuous hours) personal samples including at least one sample for each shift, for each job classification, in each work area. Initial determination is made if the employee is exposed to lead at or above the action level. August 3, 2010 E Light Electric Services

36 OSHA’S ASBESTOS STANDARD FOR THE CONSTRUCTION INDUSTRY August 3, 2010 E Light Electric Services

37 WHAT IS ASBESTOS? Asbestos is a name given to a group of naturally occurring, fibrous minerals that are uniquely resistant to heat, chemicals and electricity. The fibers are extremely fine and easily inhaled. August 3, 2010 E Light Electric Services

38 TYPICAL USES OF ASBESTOS Cement Pipes Cement siding Vinyl Products Asphalt Acoustical Tiles High Temperature Tiles Wallboard Insulating materials of all types August 3, 2010 E Light Electric Services

39 ASBESTOS HISTORY Asbestos is used in thousands of products. In many of these products there is no substitute for the asbestos. Asbestos was used far more prominently prior to 1970 in construction materials requiring insulation In 1967, asbestos was recognized as a carcinogen August 3, 2010 E Light Electric Services

40 THE PROBLEMS WITH ASBESTOS August 3, 2010 E Light Electric Services The fine fibers, when inhaled, lodge themselves in the lung tissue. They stay there, unnoticed for many years. Often cancer cells develop in the area with the lodged asbestos fiber leading to lung cancer.

41 LAWSUITS AND REGULATION The late 1960’s and early 1970’s saw thousands of law suites concerning asbestos and lung cancer. Most of the these suites were successful and most manufacturer’s changed processes to eliminate asbestos from their products. However, the products that were already installed were still a hazard if they were disturbed or the asbestos fibers were released. August 3, 2010 E Light Electric Services

42 OSHA AND ASBESTOS OSHA came into existence in 1970 and the first product they decided to regulate was asbestos.  Respirator programs were develop based on asbestos regulations  MSDS came from asbestos regulations  Hazardous material clean up and management regulations came from asbestos regulations  In short, asbestos changed the construction industry August 3, 2010 E Light Electric Services

43 THIS CLASS OSHA has separate standards for general industry and construction. This program is going to deal strictly with the construction standards What to do in the event you discover asbestos. And some key facts about asbestos. August 3, 2010 E Light Electric Services

44 THIS CLASS We will not discuss asbestos removal processes or how to mitigate asbestos as that is a subject for another class. This class is asbestos awareness and what to do when you discover asbesto. August 3, 2010 E Light Electric Services

45 TYPES OF ASBESTOS Chrysotile Amosite Crocidolite Termolite asbestos Anthophyllite asbestos Actinolite asbestos Any product contains asbestos if it contains any of the products listed above. August 3, 2010 E Light Electric Services

46 PACM Asbestos also includes ‘presumed asbestos-containing materials”. PACM Defined as thermal system insulation (TSI) and surfacing material found in buildings constructed in 1980 or before. Designation of material as PACM may be rebutted in accordance with OSHA regulations. August 3, 2010 E Light Electric Services

47 WHAT THIS MEANS TO YOU Unless an inspection of the premises has been completed by a certified expert in asbestos recognition and all the appropriate paperwork filed…….. IF YOU ARE WORKING IN A BUILDING BUILT PRIOR TO 1981…..YOU HAVE TO ASSUME ALL INSULATING MATERIALS COULD POSSIBLY CONTAIN ASBESTOS August 3, 2010 E Light Electric Services

48 WHAT IS A PACM In both the OSHA Construction Asbestos Standard (29 CFR ) and the General Industry Asbestos Standard (29 CFR ) PACM is defined as thermal system insulation (TSI) and surfacing material found in a building constructed no later than TSI is the material applied to pipes, fittings (joints, "Ts", elbows, valves, etc.), boilers, breechings, tanks, ducts or other structural components, generally to prevent heat loss or gain. August 3, 2010 E Light Electric Services

49 SURFACING MATERIALS Surfacing material refers to materials sprayed, troweled- on or otherwise applied to surfaces generally for acoustical, fireproofing, or other purposes. Examples of surfacing materials include decorative finishes on ceilings and walls, fireproofing on structural members, and acoustical plasters. August 3, 2010 E Light Electric Services

50 OSHA REQUIREMENTS OSHA requires that building owners identify PACM in their buildings and treat the PACM as asbestos- containing materials (ACM) until the materials are proven not to contain asbestos. August 3, 2010 E Light Electric Services

51 SUSPECT ASBESTOS CONTAINING MATERIALS The term "suspect ACM" does not appear in either of the OSHA standards. The term, however, has long been used by the asbestos industry to refer to any building material that is suspected of being asbestos- containing (based on appearance, usage, age of building, etc.), but has not been proven conclusively to be ACM (based on sampling and analysis, documentation, building records, etc). August 3, 2010 E Light Electric Services

52 OSHA REQUIREMENTS For OSHA’s purposes, suspect material would include any material (including TSI, surfacing, and flooring) that a building owner suspects of containing asbestos and is found in a building constructed after 1980, or any material (excepting TSI, surfacing, and flooring) found in a building constructed prior to Other typical suspect building materials would include ceiling tiles, asbestos-cement products (Transite®), and joint compound August 3, 2010 E Light Electric Services

53 OWNER’S RESPONSIBILITIES The exercise of due diligence (as noted in the OSHA asbestos standards) requires that, where a building owner knows or should have known that materials other than PACM are asbestos-containing, these materials must be treated as ACM until proven otherwise. August 3, 2010 E Light Electric Services

54 THE DIFFERENCE A building constructed prior to 1981, therefore, could contain both PACM and suspect ACM. Newer buildings (constructed after 1980) would contain only suspect ACM. August 3, 2010 E Light Electric Services

55 COURSES OF ACTION Building owners with identified PACM have two courses of action under the OSHA standards: 1) rebut or disprove the PACM designation; or 2) simply continue to treat the PACM as ACM (and follow all OSHA requirements for protecting the health and safety of workers and building occupants). August 3, 2010 E Light Electric Services

56 REBUTTING THE PACM OSHA allows a building owner to rebut the designation of PACM in two ways: Have a complete building inspection conducted according to the requirements outlined in the EPA AHERA (Asbestos Hazard Emergency Response Act) regulation. Samples would have to be collected by an AHERA-accredited Asbestos Building Inspector. All PACM (and suspect ACM, for that matter) would accordingly be included in this inspection. August 3, 2010 E Light Electric Services

57 OR…… Collect and analyzing only samples of the PACM identified in a building. OSHA allows samples to be collected by either an accredited inspector or a CIH (Certified Industrial Hygienist). Samples must be collected in the manner described in AHERA. August 3, 2010 E Light Electric Services

58 REMEMBER… If the AHERA process has not been used to rebutt the PACM, the only other option is to consider the material to be asbestos containing and take all the precautions required. August 3, 2010 E Light Electric Services

59 CLASSIFICATIONS OF ASBESTOS WORK Class I: Activities involving the removal of thermal system insulation, surfacing asbestos-containing material and presumed asbestos- containing material\ Class II: Activities involving removal of ACM other than TSI or surfacing material. Class III: Repair and maintenance operations where ACM, including TSI and surfacing material is likely to be disturbed. Class IV: Maintenance and custodial activities in which employees contact but don not disturb ACM or PACM while cleaning up waste and debris August 3, 2010 E Light Electric Services

60 VERY IMPORTANT PLEASE NOTE: ALL OF THE CLASSIFICATIONS REQUIRE EITHER THE REMOVAL, DISTURBING OR CONTACTING OF ASBESTOS!!!! In other words, asbestos, if left alone is perfectly safe. It is when we disturb it and cause the fibers to fly into the air that it can become hazardous. August 3, 2010 E Light Electric Services

61 IN OTHER WORDS……. The decision to leave asbestos alone, encapsulate it, or removing asbestos depends largely on the type of material, its location, its condition, and its exposure to mechanical damage or fiber release If you encounter asbestos products or products you suspect are asbestos, do not disturb the product and notify supervision immediately. August 3, 2010 E Light Electric Services

62 (K) COMMUNICATION OF HAZARDS - EMPLOYEE TRAINING AND INFORMATION - BASIC INFORMATION All employees covered by the standard must be informed of  Methods of recognizing asbestos, including PACM  Health effects  Relationship between smoking and asbestos in producing lung cancer  Operations that could result in exposure and protective measures and their use, as applicable  For Class III and IV work, information equivalent to the contents of EPA 20T-2003, “Managing Asbestos In-Place”  Purpose, proper use, fitting instructions, and limitations of respirators August 3, 2010 E Light Electric Services

63 WHAT IS A CARCINOGEN A substance that can cause changes that lead to cancer are called carcinogens Some carcinogens do not act on the DNA directly, but cause cancer in other ways, such as causing cells to divide at a faster rate August 3, 2010 E Light Electric Services

64 CARCINOGENS / CANCER INFO Carcinogens do not cause cancer in every case, all the time. Substances classified as carcinogens may have different levels of cancer-causing potential Some may cause cancer only after prolonged, high levels of exposure August 3, 2010 E Light Electric Services

65 CANCER RISKS For any particular person, the risk of developing cancer will depend on many factors, including:  The length of exposure to the carcinogen  The intensity of exposure to the carcinogen  The person’s genetic makeup August 3, 2010 E Light Electric Services

66 DETERMINATION OF SUBSTANCES AS CARCINOGENS Scientists obtain most data from lab studies (both culture & animals) In most cases, carcinogens are first found to cause cancer in lab animals and are later found to cause cancer in people Basil cell skin cancer August 3, 2010 E Light Electric Services

67 LAB STUDIES Most studies expose lab animals to doses that are higher than common human exposures For most carcinogens, it is assumed that that those that cause cancer in animals, will cause cancer in humans. August 3, 2010 E Light Electric Services

68 EPIDEMIOLOGIC STUDIES Epidemiologic studies look at the factors that might affect the occurrence of cancer in human populations August 3, 2010 E Light Electric Services

69 STUDY SUMMARY By combining data from both types of studies, scientists are able to make an educated assessment of a substance’s cancer causing capability. When the available evidence is compelling, but not felt to be conclusive, the substance may be considered to be a probable carcinogen. August 3, 2010 E Light Electric Services

70 HOW ARE CARCINOGENS CLASSIFIED The most widely used system is IARC (International Agency for Research on Cancer). Is a part of the WHO (World Health Organization) IARC has evaluated the cancer causing potential of about 900 likely candidates in the last 30 years. August 3, 2010 E Light Electric Services

71 CARCINOGEN GROUPS Group 1: Carcinogen to humans Group 2A: Probably carcinogenic to humans Group 2B: Possibly carcinogenic to humans Group 3: Unclassifiable as to carcinogenicity to humans Group 4: Probably not carcinogenic to humans August 3, 2010 E Light Electric Services

72 NATIONAL TOXICOLOGY PROGRAM (NTP) Used in the U.S. – NTP releases the “Report on Carcinogens” (RoC) every two years. Identifies 2 groups of agents:  Known to be human carcinogens  Reasonably anticipated to be human carcinogens.  Unlike IARC, RoC does not list substances that have been studied & found not to be carcinogens. August 3, 2010 E Light Electric Services

73 KNOWN HUMAN CARCINOGENS Arsenic Asbestos Benzene Beryllium Cadmium Chromium Ethylene Oxide Nickel Plutonium 239 And many others August 3, 2010 E Light Electric Services

74 SMOKING Persons who smoke tobacco or other products have been shown to have a much higher risk of developing health problems including cancer when also exposed to asbestos. August 3, 2010 E Light Electric Services

75 HOW TO IDENTIFY ASBESTOS? 1. What is it used for? 2. How old is it? 3. Is it fibrous in nature? 4. What color is it? Asbestos is typically white or gray in color where as fiberglass is typically yellowish in color. 5. Sample testing to be sure. August 3, 2010 E Light Electric Services
