Asbestos Awareness Objectives Background Standards Contracting Repair/Removal Maintenance Activities Background Asbestos Origin Properties Uses Diseases Asbestos Is a naturally occurring fibrous mineral which is mined like diamonds and comes in two forms: – – Serpentine - snake like Amphibole - needle like Mineral – – – – content includes: Silica Water Iron Magnesium (may include) Asbestos Types Chrysotile - 95%type used in the United States Amosite - Used to harden Crocidolite - Frequently found as a contaminant of Amosite Origins Found in nature Arctic Deserts Mountains Snow Drinking water Origins continued Mined USA Canada Russia South Italy Africa Properties Tensile strength Flexibility Heat Resistant Chemical Resistant Uses Historical – – – – 480 BC - Candle wicks Egyptians wove asbestos into cremation shrouds Romans used in textiles like cremation shrouds, lamps, napkins and table cloths Wide spread uses in the late 1800 and 1900 Present Day – – – – Acoustical spray-on asbestos TSI -Thermal system insulation brakes/clutches vinyl floor tile Diseases Asbestosis - Scarring of the lungs due to cell damage from inhalation of asbestos fibers. Mesothelioma - Cancer of the lining around the lungs called the mesothelium. Fatal Lung Cancer - Cancer of the bronchioles. Synergistic effect with cigarette smoking. Standards COMDTINST 6260.16A 29 CFR 1910.1001 (General Industry) 29 CFR 1926.1101 (Construction) 40 CFR 61.156 (NESHAPS) Vocabulary ACM: Asbestos-containing material. Material which contains one or more percent asbestos. Friable/Nonfriable: Friable-ACM which can be crumbled under hand pressure. Nonfriable-ACM which can not be crumbled or become airborne easily such as floor tile or transite. TSI: Thermal system insulation PACM: Presumed asbestos-containing material. TSI or surfacing materials installed prior to 1980. Competent person/Qualified person: Someone who is capable of identifying existing and predictable hazards in the surroundings or work conditions which are unsanitary, hazardous or dangerous especially in regards to asbestos and who is authorized to select the appropriate control strategy and can take prompt corrective actions to eliminate them. Vocabulary of Standards PEL: OSHA Permissible Exposure Limit-limit which is based on an 8hour time weighted average and can not be exceeded. (This is law.) TWA: Averaged airborne concentration of a substance over a given period of time such as eight hours. Excursion Limit: A 30 minute limit which must not be exceeded more than twice per day. TLV: a time weighted average concentration for a normal 8-hour work day and a 40-hour work week, to which nearly all workers may be repeatedly exposed, day after day, without adverse effects. (recommendation from ACGIH). Criteria PEL - 0.01 f/cc Excursion Limit - 1.0 f/cc Program Elements Responsibilities Asbestos Management Plan Identification Repair and Removal Asbestos Management Plan Designation of a Coordinator Identification Inventory Labeling Management in Place Identification Sampling - Sampling should be done as outlined in the handout provided and provided to MLCPAC (kse) to process for analysis. Analysis lab. - Analysis is done by an accredited Sampling Who can Sample - Legally the person sampling must be A CIH or certified by attending an AHERA course Training Requirements to Sample - Classes referred to as AHERA certified by the EPA Uses of Samples Results - Samples taken by personnel who are not certified to take samples can only be used for establishing the cost of the project. The can not be used by the contractor.

Except at the CG Yard, Base Ketchikan and underway casualty repair activities. Contract Concerns MLCPAC Inform (kse) Review spec packages contractors Standards to be followed Possible presents of asbestos Recommend independent consulting firm to oversee the abatement. Signs Maintenance Activities Involving ACM Buffing floor tiles Replacing gaskets Replacing brake pads Definitions for Maintenance Operations Wet Methods: Wetting the material to be removed prior to disturbing it. Prefer the use of amended water over plain water. Amended Water: Water which has had a chemical added to make it penetrate and adhere to the material be removed more readily. HEPA: high efficiency particulate air. A filter or filtration system designed to trap and retain 99.97 % of all particles 0.3 micrometers or greater. Maintenance Procedures Involving ACM Buffing and waxing floor tiles Must have a heavy wax coating No abrasive buffers Gasket Must Brake material replacement be done using wet methods replacement Must use HEPA vacuum drum to catch fibers from asbestos brakes or Interim wet methods Prohibited Procedures Sanding, drilling, grinding, sawing with high speed abrasive discs, anything that causes asbestos fibers to be released from the material. Dry sweeping, shoveling or other forms of dry clean-up and use of compressed air to remove asbestos debris. Actual Abatement Activities Beyond the scope of this training. Standards are: Complicated Lengthy Confusing Require extensive training Summary Asbestos is used throughout the Coast Guard in many ways, e.g. insulation, gaskets, brakes, etc. Exposure to asbestos can cause diseases that can be fatal. Asbestos must be identified, inventoried, labeled, removed or managed in place. Coast Guard personnel are prohibited from working with asbestos (with notable exceptions). If personnel must work with asbestos, they must have extensive training.
