Title: Asbestos Awareness Training


1
Asbestos Awareness Training
  • Presented By
  • Winchester, Environmental Consultants Inc.

2
Objective
  • To introduce you to asbestos, including
  • Types of asbestos
  • Properties of asbestos
  • Places you may encounter asbestos in your work
  • Selected regulations that may effect you.

3
What is asbestos?
  • A naturally Occurring mineral
  • Has many beneficial properties
  • Cheap
  • Chemical resistant
  • Fire resistant
  • Low conductivity
  • But it can be deadly
  • Three most common types
  • Chrysotile (white)
  • Amosite (brown)
  • Crocidolite (blue)

4
What is ACM?
  • Asbestos Containing Material
  • Also known as ACBM (asbestos containing building
    material)
  • Any material containing more than 1 of asbestos
    by weight
  • Can be friable or non-friable
  • Friable able to be crushed or reduced to
    powder under normal hand pressure

5
Why is asbestos harmful?
  • When disturbed it can break down into sharp
    fibers and be breathed in.
  • The fibers lodge in the lungs and do not
    dissolve.
  • Blue and brown asbestos can be even more
    hazardous than white.
  • Inhaling asbestos fibers can lead to three main
    diseases
  • Asbestosis
  • Lung cancer
  • Mesothelioma

6
HEALTH RISKS
  • ASBESTOS FIBRE BUNDLES CAN SPLIT WITH SMALL FINE
    FIBRES BREAKING AWAY.
  • IF INHALED THE BODY IS ABLE TO RESIST MOST OF THE
    LARGE PARTICLES, BUT FINE FIBERS, TOO SMALL TO
    SEE, CAN LODGE DEEP IN THE LUNGS

7
WHEN IS ASBESTOS A RISK TO HEALTH ?
  • CONSIDER THE TYPE OF PRODUCT.
  • HOW WELL IS THE ASBESTOS BONDED INTO IT?
  • IS IT LIKELY TO CONTAIN A SMALL OR LARGE AMOUNT
    OF ASBESTOS?
  • And, consider the condition
  • GOOD? E.G. SEALED, PAINTED.
  • DAMAGED? EXTENT OF DAMAGE

8
ASBESTOSIS
  • Heavy and regular exposure.
  • Incurable.
  • Restricts lung function.
  • Increased risk of lung cancer.

9
LUNG CANCER
  • Smoking multiplies risk.
  • Smoker 15 times more likely to suffer lung
    cancer.
  • Smoking asbestos worker 75 times more likely to
    suffer lung cancer.

10
MESOTHELIOMA
  • Caused by all kinds but particularly blue
    asbestos.
  • Form of cancer.
  • Small dose required.
  • Incurable, painful.
  • 20- 40 years from exposure to development.
  • Deaths estimated to peak at 25,000 between 2011
    and 2015.

11
Why is it still a problem?
  • Between 1940s and 1980s asbestos used extensively
    in US as building material.
  • Some uses banned in the 1980s.
  • Thousands of tons of asbestos still remain in
    buildings.
  • About 4 to 5 million non-domestic premises may
    contain asbestos.

12
Which premises could contain asbestos?
  • Answer any type (pre-1988).
  • Schools.
  • Factories.
  • Offices.
  • Farms.
  • Hospitals.
  • Homes.

13

  • PANELS, UNDER STAIRS, DOOR-
  • LININGS, CLADDING TO DUCTS
  • FLUES - FROM BOILERS / WATER HEATERS
  • RAINWATER PIPES / GUTTERING
  • WATER STORAGE TANKS

Common School Asbestos Uses
  • electrical insulation
  • floor tiles
  • paper and cardboard
  • decorative textural coatings
  • pipe lagging
  • boiler insulation
  • acoustic tile

28
Why are people at risk?
  • Asbestos is most harmful if fibres are released
    into the air.
  • cutting, machinery, removal, drilling, sawing,
    repair/replacement, unintentional damage.
  • People may have been unknowingly exposed to
    asbestos.
  • Previous regulations did not cover those people
    who could come into contact with asbestos
    unknowingly.

29
Who are these people?
  • Heating and ventilation engineers.
  • Roofing contractors.
  • Fire and burglar alarm installers.
  • General maintenance staff.
  • Electricians.
  • Plumbers.
  • Carpenters and joiners.
  • Plasterers.
  • Gas fitters.
  • Cable layers.
  • Demolition workers.
  • Painters and decorators.

30
EPA, OSHA and AHERA require schools to
  • Assess any buildings for the presence of
    asbestos.
  • Develop a management plan for any asbestos found.
  • Periodically monitor the buildings for any
    changes in the condition of the ACM.
  • Inform all private contractors and staff about
    the locations of ACM.

31
Who is responsible for following the regulations?
  • Those with a contractual obligation in relation
    to maintenance and/or repair of premises could
    include owners, occupiers, managing agents and
    others.
  • Person in control where no contract or tenancy
    agreement exists.
  • There may be joint control.
  • Every person shall cooperate with the responsible
    party to enable them to comply with their duties.

32
Where does the law apply?
  • All non-domestic premises.
  • Doesnt apply to domestic premises themselves.
  • Except in the cases of renovation or demolition.

33
Assessing whether premises contain asbestos
  • Only a state licensed asbestos inspector may
    determine with certainty the presence of ACM by
  • looking at building plans etc.
  • consulting others, e.g. architects, employees
  • carrying out a thorough inspection of the
    premises.
  • Assess the condition of these materials.
  • Record the findings.
  • Material can be presumed ACM but must be lab
    tested to be confirmed negative.

34
AHERA
  • Asbestos Hazard Emergency Response Act.
  • Set forth by the EPA to regulate asbestos in
    public schools and private non-profit schools.
  • Dictates, cleanup actions, monitoring, and final
    clearance of asbestos projects.

35
What is an Asbestos Project?
  • Under AHERA, there are four types of asbestos
    projects.
  • Class I Includes removal of friable materials,
    generally the most dangerous work
  • Class II Includes removal of non-friable
    material
  • Class III Includes repair or cleanup of Class I
    and II work in addition to other projects where
    staff might disturb asbestos
  • Class IV Includes working in areas where ACBM is
    present but not likely to be disturbed.

36
Identifying asbestos
  • Presume asbestos.
  • Conclude it is not asbestos (requires strong
    evidence).
  • OR
  • Establish identity by sampling.
  • OR
  • A combination of all of the above.

37
Assessing the risk Decisions
  • If in good condition
  • leave it in place and
  • introduce a management system.
  • If in poor condition
  • seal it or enclose it or
  • remove it.

38
Assessing the risk Decisions
  • Attention!!
  • Damaged asbestos is likely to release fibres into
    the air.
  • Need to take immediate action to protect people.
  • Licensed asbestos contractor may be necessary.

39
Assessing the risk Action
  • Prepare and implement a written action plan.
  • When materials are to remain in premises
  • inform others of their location and condition
  • carry out regular checks on the condition of the
    material and
  • review and revise the plan and update the
    asbestos record as necessary.

40
Removal and Repair
  • School system employees can remove or repair gt 3
    square or linear feet of ACM if they have been
    given proper training.
  • Two types of removal, gross and glove bag.
  • Repair operations, the candystripe.
  • When removing ACM, the two most important things
    to remember are
  • Try to remove the material intact
  • Wet methods
  • Airflow is also important

41
Personal Protective Equipment for Removal and
Repair
  • Respirator with appropriate filters
  • Limitations of respirators
  • Protective clothing
  • Boots
  • Glasses
  • Gloves

42
What are the consequences of poor management?
  • Asbestos is very useful but also harmful if
    fibres are released.
  • 3000 people die each year from asbestos-related
    diseases and 25 of these have worked in building
    trades.
  • A bad survey is potentially worse than no survey
    at all.
  • Enforcement action.

43
How are the Regulations going to be implemented?
  • Local Authorities, Bureau of Public Health
  • Building inspectors
  • EPA region III
  • OSHA

44
Summary
Asbestos is relatively safe if handled with
proper care Everybody is responsible for helping
to comply with regulations State licensed
workers, supervisors, inspectors etc. are
required for most jobs Friable versus
non-friable Wet Methods When in doubt, check it
out!
