 Amosite, and Crocidolite
>3,000 Building Products
Desirable Physical Properties
ACM >1% Asbestos

HISTORY OF ASBESTOS USE
 Greek Blankets
 Egyptian Bricks
 Fire Protection

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

SPRAY-ON FIREPROOFING

SPRAY-ON FIREPROOFING

FLOOR TILE

PIPE INSULATION

Boiler Wrapping and Cement
Pipes

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

ROUTES OF ENTRY
 Inhalation
 Ingestion
But NOT
• Absorption
• Injection

RESPIRATORY SYSTEM ANATOMY

HEALTH EFFECTS
 Asbestosis
 Lung Cancer
 Mesothelioma
 Other Cancers
 Pleural Plaques/Asbestos Warts



Inhalation Hazard
Must Be Disturbed
Latency Period (15 to 40 years)

EXPOSURE MONITORING
 Air Sampling
 Area Samples
 Personal Samples

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

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

CARTRIDGES
 Mechanical Filters
 N,R,P
 95, 99, 100
 Chemical Filters
 Absorbent
 Adsorbent

MASKS
 Dust Masks
 1/2 Face Masks
 Negative Pressure
 Positive Pressure
 Full Face Masks
 Negative Pressure
 Positive Pressure

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

ASSESSMENT OF ACM DAMAGE
 Physical Damage
 Cuts, Breakage, Alteration, Friction
 Water Damage
 Delamination
 Deterioration

RECOGNITION OF DAMAGE

LOCATION OF ACM
 Review the Comprehensive Building Survey
 Observe the Warning Labels
