1Asbestos Awareness Training Presented By:Winchester, Environmental Consultants Inc.
2Objective To introduce you to asbestos, including: Types of asbestos Properties of asbestosPlaces you may encounter asbestos in your workSelected regulations that may effect you.
3What is asbestos? A naturally Occurring mineral Has many beneficial propertiesCheapChemical resistantFire resistantLow conductivityBut it can be deadlyThree most common typesChrysotile (white)Amosite (brown)Crocidolite (blue)
4What is ACM? Asbestos Containing Material Also known as ACBM (asbestos containing building material)Any material containing more than 1% of asbestos by weightCan be “friable” or “non-friable”Friable = “able to be crushed or reduced to powder under normal hand pressure”
5Why 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:AsbestosisLung cancerMesothelioma
6HEALTH RISKSASBESTOS 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
7WHEN 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
8ASBESTOSIS Heavy and regular exposure. Incurable. Restricts lung function.Increased risk of lung cancer.
9LUNG CANCER Smoking multiplies risk. Smoker 15 times more likely to suffer lung cancer.Smoking asbestos worker 75 times more likely to suffer lung cancer.
10MESOTHELIOMA Caused by all kinds but particularly blue asbestos. Form of cancer.Small dose required.Incurable, painful.years from exposure to development.Deaths estimated to peak at 25,000 between 2011 and 2015.
11Why is it still a problem? Between 1940s and 1980s asbestos used extensively in US as building material.Some uses banned in the 1980’s.Thousands of tons of asbestos still remain in buildings.About 4 to 5 million non-domestic premises may contain asbestos.
12Which premises could contain asbestos? Answer… any type (pre-1988).Schools.Factories.Offices.Farms.Hospitals.Homes.

28Why 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.
29Who 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.COVERS A WIDE RANGE OF BUILDING AND ASSOCIATED TRADES FROM ELECTRICIANS AND PLUMBERS TO BURGLAR ALARM INSTALLERSPAINTERS/DECORATORS MORE AT RISK AT WORK THAT DEEP SEA DIVERS
30EPA, 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.
31Who 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.
32Where does the law apply? All non-domestic premises.Doesn’t apply to domestic premises themselves.Except in the cases of renovation or demolition.
33Assessing 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.
34AHERA 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.
35What is an Asbestos Project? Under AHERA, there are four types of asbestos projects.Class I: Includes removal of friable materials, generally the most dangerous workClass II: Includes removal of non-friable materialClass III: Includes repair or cleanup of Class I and II work in addition to other projects where staff might disturb asbestosClass IV: Includes working in areas where ACBM is present but not likely to be disturbed.
36Identifying asbestos Presume asbestos. Conclude it is not asbestos (requires strong evidence).OREstablish identity by sampling.A combination of all of the above.
37Assessing the risk: Decisions If in good condition:leave it in place; andintroduce a management system.If in poor condition:seal it or enclose it; orremove it.
38Assessing 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.
39Assessing 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; andreview and revise the plan and update the asbestos record as necessary.
40Removal and RepairSchool system employees can remove or repair > 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 methodsAirflow is also important
41Personal Protective Equipment for Removal and Repair Respirator with appropriate filtersLimitations of respiratorsProtective clothingBootsGlassesGloves
42What 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.
43How are the Regulations going to be implemented? Local Authorities, Bureau of Public HealthBuilding inspectorsEPA region IIIOSHA
44Summary Asbestos is relatively safe if handled with proper care Everybody is responsible for helping to comply with regulationsState licensed workers, supervisors, inspectors etc. are required for most jobsFriable versus non-friableWet MethodsWhen in doubt, check it out!
