History

History Past Uses: Insulation of Huts Strengthen Pottery Mummification Cremation Lamp Wicks Clothing and Cloths Movies

Modern Uses Fireproofing Flooring material Thermal Systems Insulation Adhesives / Glues Plaster Acoustical material

Continuing Legacy

Definitions

Definitions ACM (Asbestos Containing Material) Material that contains greater than one percent (>1%) asbestos (OSHA/EPA) ACBM (Asbestos Containing Building Material) Is ACM in building construction material or mechanical system material only

Definitions PACM (Presumed Asbestos Containing Material) Material installed prior to 1980 Surfacing material TSI (thermal systems insulation Resilient floor covering

Definitions Friable Asbestos, when dry, that can be crushed, crumbled, pulverized and reduce to powder by hand pressure

Health Effects

Why is asbestos dangerous

Health Effects How does a contaminant enter our bodies? Inhalation Primary Route of Entry for Asbestos Ingestion Secondary Route of Entry for Asbestos Absorption Injection

Health Effects

Health Effects Asbestosis Fibrotic scarring of the lung Restrictive lung disease Reduces lung capacity Dose Response Relationship Latency Period 15-30 years Progressive disease in the absence of continued exposure

Health Effects Lung Cancer Abnormal growth of cells in the lung Dose-Response Relationship Latency Period 30 years Increased Risk with Smoking

Health Effects

Mesothelioma Rarest of the diseases Health Effects Cancer of the chest cavity or in the lining of the abdominal cavity No dose response relationship Latency Period 30-50 years

Health Effects Summary

Detection, Identification, Assessment

Inspection and Assessing the Condition of ACM

Summary of Process Assemble equipment and supplies Obtain floor plan Walk through of building Enter every room and utility space Locate ACM materials specified in construction documents Test all surfaces for friability For all suspect materials to be sampled, identify and draw homogenous sampling areas All friable suspect materials and TSI, identify appropriate functional spaces Assess all friable suspect ACM and TSI

Surfacing Materials Material that is sprayed-on or trowelled on Spray-on fireproofing Plaster Hard Plaster Acoustical Plaster Textured Paint Substrates that are not suspect Cinder blocks Steel Wood

Thermal System Insulation Heat gain or heat loss Materials that can be considered non-asbestos Fiberglass Rubber Styrofoam Suspect TSI Boiler and breeching block Insulation Cements and pipe fititng muds Gasketing material

Miscellaneous Materials Primary materials Floor sheeting & mastics Ceiling tiles Other Suspect Transite Sheetrock Joint Compound Levelastics Glazings and Caulkings Construction adhesives

Conducting Inspection Samples are to be collected down to the substrate

Conducting Inspection Check under fiberglass insulation

Conducting Inspections Was new fiberglass insulation checked for contamination?

Inspecting Boilers Was interior sampled? Firebrick Cement Mortar Gasketing Rope

Duct Insulation Was the interior accessed for contamination? Is the insulation fiberglass? Was the seams and edges inspected? Is there adhesive underneath the fiberglass insulation?

Conducting Inspections Determine the extent of material throughout the building

Conducting Inspections Was the exterior surveyed? Asbestos adhesive on roof slate

Asbestos flooring layers 1. Asbestos floor tile and mastic 2. Asbestos leveling compound 3. Concrete floor layer 4. Concrete floor

Conducting Inspections Were machines and electrical closets accessed?

Assessment of Suspect Asbestos- Containing Materials

Suspect material tested for friability

Assessment Procedures Assessment of Friable Materials 1. Damaged or significantly damaged friable TSI 2. Damaged friable surfacing ACBM 3. Significantly damaged friable surfacing ACBM 4. Damaged or significantly damaged friable miscellaneous 5. ACBM 6. ACBM with potential for damage 7. ACBM with potential for significant damage 8. Any remaining friable ACBM or friable suspected ACBM

Assessment of Surfacing Material Significantly Damaged Surface crumbling or blistering 10% Distributed or 25% Localized 10% material hanging from the surface, deteriorated or showing adhesive failure Water stains, gouges, or mars 10% Distributed or 25% Localized

Assessment of Surfacing Material Damaged The surface crumbling, blistered, water-stained, gouged, marred or otherwise abraded Less than 10% Distributed or Less than 25% Localized Good Condition Material with no visible damage or deterioration, or showing only very limited damage or deterioration

Assessment of TSI Significantly Damaged Missing jackets on 10% of the piping Crushed, heavily gouged, or punctured insulation 10% Distributed or 25% Localized

Assessment of TSI Damaged A few water stains Less than 10% insulation missing jackets Crushed, heavily gouged, or punctured insulation Less than 10% Distributed or Less than 25% Localized Good Condition Material with no visible damage or deterioration, or showing only very limited damage or deterioration

Potential for Disturbance Contact Damage Vibration Damage Air Erosion

Options for controlling Asbestos

Response Actions Operations & Maintenance Removal Encapsulation Repair Enclosure

Response Actions AHERA Says: Must be implemented in a timely fashion Must Protect Human Health & the Environment (HH&E) and, the school district may select the least burdensome response action.

Response Actions AHERA Says: For damaged or significantly damaged TSI, at least repair the material. Remove if it is not feasible Maintain the material in an intact and undamaged state

Response Actions AHERA Says: For damaged miscellaneous material or damaged surfacing material, the school may select removal, encapsulation, enclosure or repair.

Response Actions AHERA says: That for significantly damaged miscellaneous material or significantly damaged surfacing material; Must immediately isolate the functional space and restrict access, unless it is not necessary to protect HH&E Consider removal unless Enclosure or Encapsulation will protect HH&E

Response Actions AHERA Says: For all other friable material, the minimal response action is operations and maintenance. If the material is non-friable, no response action is required, unless the material becomes friable.

Response Actions AHERA Says: For damaged or significantly damaged TSI, at least repair the material. Remove if it is not feasible Maintain the material in an intact and undamaged state

Response Actions AHERA says: That for significantly damaged miscellaneous material or significantly damaged surfacing material; Must immediately isolate the functional space and restrict access, unless it is not necessary to protect HH&E Consider removal unless Enclosure or Encapsulation will protect HH&E
