Title: Asbestos Awareness


1
Asbestos Awareness
2
Objectives
  • Background
  • Standards
  • Contracting
  • Repair/Removal
  • Maintenance Activities

3
Background
  • Asbestos
  • Origin
  • Properties
  • Uses
  • Diseases

4
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)

5
Asbestos Types
  • Chrysotile - 95type used in the United States
  • Amosite - Used to harden
  • Crocidolite - Frequently found as a contaminant
    of Amosite

6
Origins
  • Found in nature
  • Arctic
  • Deserts
  • Mountains
  • Snow
  • Drinking water

7
Origins continued
  • Mined
  • USA
  • Canada
  • Russia
  • South Africa
  • Italy

8
Properties
  • Tensile strength
  • Flexibility
  • Heat Resistant
  • Chemical Resistant

9
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

10
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.

11
Standards
  • COMDTINST 6260.16A
  • 29 CFR 1910.1001 (General Industry)
  • 29 CFR 1926.1101 (Construction)
  • 40 CFR 61.156 (NESHAPS)

12
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.

13
Vocabulary of Standards
  • PEL OSHA Permissible Exposure Limit-limit which
    is based on an 8-hour 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).

14
Criteria
  • PEL - 0.01 f/cc
  • Excursion Limit - 1.0 f/cc

15
Program Elements
  • Responsibilities
  • Asbestos Management Plan
  • Identification
  • Repair and Removal

16
Asbestos Management Plan
  • Designation of a Coordinator
  • Identification
  • Inventory
  • Labeling
  • Management in Place

17
Identification
  • Sampling - Sampling should be done as outlined in
    the handout provided and provided to MLCPAC (kse)
    to process for analysis.
  • Analysis - Analysis is done by an accredited lab.

18
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.

19
Analysis
  • PLM-Polarized Light Microscopy
  • TEM-Transmission Electron Analysis

21
Repair and Removal
  • Prohibited Activities
  • Contract Concerns
  • PACM

22
Prohibited Activities
  • Coast Guard personnel are prohibited from
    repairing or removing asbestos-containing
    materials.
  • Except at the CG Yard, Base Ketchikan and
    underway casualty repair activities.

23
Contract Concerns
  • MLCPAC (kse) Review spec packages
  • Inform contractors
  • Standards to be followed
  • Possible presents of asbestos
  • Recommend independent consulting firm to oversee
    the abatement.

24
Signs
25
Maintenance Activities Involving ACM
  • Buffing floor tiles
  • Replacing gaskets
  • Replacing brake pads

26
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.

27
Maintenance Procedures Involving ACM
  • Buffing and waxing floor tiles
  • Must have a heavy wax coating
  • No abrasive buffers
  • Gasket material replacement
  • Must be done using wet methods
  • Brake replacement
  • Must use HEPA vacuum drum to catch fibers from
    asbestos brakes or
  • Interim wet methods

28
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.

29
Actual Abatement Activities
  • Beyond the scope of this training.
  • Standards are
  • Complicated
  • Lengthy
  • Confusing
  • Require extensive training

30
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.
