  1. ASBESTOS AWARENESS A Two Hour Introductory Course Rowan University Environmental Health and Safety X 5105 ehs@rowan.edu www.rowan.edu/facilities/ehs

  2. COURSE OVERVIEW • Introduction • Identification of Asbestos • History and Uses of Asbestos • Routes of Entry • Health Effects of Asbestos Exposure • Exposure Monitoring

  3. COURSE OVERVIEW • Protection From Asbestos Exposure • Assessment of ACM Damage • Location of ACM • Summary/Questions and Answers • Adjourn

  4. WHAT IS ASBESTOS? • Naturally Occurring “A Rock” • Silicate Mineral • Chemical Resistant • Longitudinal Cleavage • Shape • Serpentine • Chrysotile • Amphibole • Amosite, and Crocidolite • >3,000 Building Products • Desirable Physical Properties • ACM >1% Asbestos

  5. HISTORY OF ASBESTOS USE • Greek Blankets • Egyptian Bricks • Fire Protection

  6. WHERE CAN YOU FIND ASBESTOS? EVERYWHERE • Insulation • Friction Products • Construction Materials • Resilient Coatings • Fireproofing • Clothing

  7. SPRAY-ON FIREPROOFING

  8. SPRAY-ON FIREPROOFING

  9. FLOOR TILE

  10. PIPE INSULATION

  11. Boiler Wrapping and Cement Pipes

  12. FRIABLE VS. NONFRIABLE • Friable – asbestos capable of being released into the air by hand pressure. • Non-Friable – must use mechanical means to become friable.

  13. ROUTES OF ENTRY • Inhalation • Ingestion • But NOT • Absorption • Injection

  14. RESPIRATORY SYSTEM ANATOMY

  15. HEALTH EFFECTS • Asbestosis • Lung Cancer • Mesothelioma • Other Cancers • Pleural Plaques/Asbestos Warts • Inhalation Hazard • Must Be Disturbed • Latency Period (15 to 40 years)

  16. EXPOSURE MONITORING • Air Sampling • Area Samples • Personal Samples

  17. PROTECTION FROM EXPOSURE-PPE • Disposable Suits • Disposable Footwear • Disposable Gloves • If Using Chemicals - Add for Specific Chemical

  18. PROTECTION FROM EXPOSURE-RESP. • Best Protection From Exposure • You Need to Wear the Right Mask With the Right Accessories • YOU MAY NOT WEAR A RESPIRATOR AT YOUR JOB UNLESS YOU HAVE BEEN TRAINED AND CLEARED FOR USE

  19. CARTRIDGES • Mechanical Filters • N,R,P • 95, 99, 100 • Chemical Filters • Absorbent • Adsorbent

  20. MASKS • Dust Masks • 1/2 Face Masks • Negative Pressure • Positive Pressure • Full Face Masks • Negative Pressure • Positive Pressure

  21. PERSONAL PROTECTION - HYGIENE • The Best Protection Is Common Sense • Wash Your Hands and Face Frequently • No Eating, Drinking, or Smoking During Asbestos Work • If You Get Dirty, Change and Wash Your Clothes Separately

  22. ASSESSMENT OF ACM DAMAGE • Physical Damage • Cuts, Breakage, Alteration, Friction • Water Damage • Delamination • Deterioration

  23. RECOGNITION OF DAMAGE

  24. LOCATION OF ACM • Review the Comprehensive Building Survey • Observe the Warning Labels

  25. EMERGENCY PROCEDURES • Major Fiber Release (> 3 sq.ft) • Stop Work Immediately • Do Not Attempt Clean-up • Secure Area • Notify Supervisor • Contact Emergency Personnel • Do Not Reenter Area Until Instructed To Do So

  26. RULES AND REGULATIONS • OSHA • EPA • New Jersey Subchapter 8

  27. ACBM MANAGEMENT • Abatement • O&M

  28. ABATEMENT ACTIVITIES • Encapsulation • Enclosure • Removal

  29. ABATEMENT ACTIVITIES • Survey to Identify ACM • Project Designer • Occupant Notification • Work Area Containment • Posting of Work Areas • Engineering Controls/PPE • Air Monitoring • Accredited Contractor

  30. O&M ACTIVITIES • In-House Small Scale, Short Duration Projects • Maintenance or Repair Only • 160 Square Feet/260 Linear Feet/35 Cubic Feet • Trained Personnel • Schedule and Coordinate with EH&S prior to activity (including floor tile and other non-friable material)

  31. Quiz • What is Asbestos? • Name 3 Building Materials That May Contain Asbestos? • Name 3 Diseases Associated With Asbestos Exposure? • When is Asbestos a Health Hazard? • What Greatly Increases the Risk of Lung Cancer? • What Should You Do If You Identify Damaged ACM?

  32. ANY QUESTIONS?? ? ? ?

  33. THANK YOU!!
