  • The state has mandated Asbestos Awareness Training for all employees that work in facilities that contain asbestos.

Asbestos Awareness Asbestos Awareness Presentation Transcript

  • Asbestos Awareness Training
    • Widely used, mineral based
    • material
    • Resistant to heat & corrosive
    • chemicals
    • Fibers may range from coarse
    • to silky
    WHAT IS ASBESTOS?
  • When is Asbestos Dangerous?
    • When it becomes airborne.
    • Fibers are so light it hang in the air for days.
    • If you step in asbestos you will push it back into the air.
    • It can go through air ducts, under doors, down halls and stairs.
  • Air Sampling
    • Air pumps pull the air through a filter.
    • The fibers collect on the filter.
    • The fibers are counted with the use of a microscope.
    • Asbestos is measured in fibers per cubic centimeter (f/cc) of air.
  • A Single Asbestos Fiber Human Hair FiberglassFiber AsbestosFiber Asbestos Fibers are Hollow.
  • Areas Where Asbestos Can Be Found
    • * Suspended ceiling tiles
    • * Thickening agents in paints
            • * Pipe insulation
            • * Fireproof drapes and curtains
            • * Vinyl flooring and mastic (glue)
            • * Friction products (brake &
            • clutch facings)
            • * Reinforcing materials (cement pipe &
            • sheet materials)
            • * Primary insulation and lagging material
            • for high temperature machinery,
            • boilers, and piping
  • Asbestos pipe and boiler insulation does not present a hazard unless the protective canvas covering is cut or damaged in such a way that the asbestos underneath is actually exposed to the air. DANGER Contains Asbestos Fibers Avoid Creating Dust Cancer & Lung Disease Hazard DANGER
  • Vinyl Floor Tiles Acoustical Ceiling Tile Pipe Insulation Asbestos Board
  • Why is it used?
    • Good insulator for heat, sound, fire, etc.
    • Plentiful (naturally occurring, easy to mine and mill.
    • Stronger than steel.
  • The Two States of Asbestos Materials
    • Friable
    • Non-friable
  • Friable
    • Able to crumble into powder with hand pressure when dry.
    • Dangerous when airborne.
    • Examples:
    • Boiler insulation
    • Spray-on fireproofing
    • Popcorn ceiling (Spray-on)
  • Non-Friable
    • May become Friable or airborne through deterioration or processes that disturb.
    • Examples:
    • Vinyl Floor Tile
    • Ceiling Tile
  • Can asbestos be identified visually? There is no way to visually identify asbestos. Many materials that contain asbestos look just the same as materials that don't. The only way to confirm that a material is asbestos is to take samples and analyze the material in a laboratory. Therefore, it is best to treat anything that looks like it may contain asbestos as if it does until it is analyzed and proven to not contain any asbestos.
  • Three Types Found in Buildings Chrysotile Amosite Crocidolite
    • Unmilled mineral asbestos (chrysotile).
    Chrysotile
  • Respirators
    • Protection Factor (PF)
    • Maximum Use Levels (MUL)
    • Permissible Exposure Limit (PEL)
  • EXPOSURE LIMITS
    • OSHA PEL = .1f/cc for 8 hr time weighted avg
    • Average adult breathes in 10 M3 of air/shift
    • PEL = 1 million fibers per shift.
  • Working Safely with ACM’s
    • If you have reason to suspect that something is asbestos, either because it is labeled as such, or because it something that is likely to contain asbestos (9" floor tile, for example) DO NOT DISTURB IT. Never:
    • Drill
    • Hammer
    • Cut
    • Saw
    • Break
    • Damage
    • Move
    • Disturb
  • Control Methods
    • Limited activity when in contact with ACMs
    • Encapsulation.
    • Enclosure.
    • Repair.
    • Removal.
    • Operations and Maintenance.
  • Building Systems
    • Structural
    • Mechanical
    • Electrical
    • Architectural Finishes
    • Other
  • HVAC SYSTEM
    • Block or board insulation
    • Blanket or batt insulation.
    • Gasket material
    • Rope filler
    • Valve packing
    • Vibration-dampening cloth
  • Plumbing System
    • Pipe Insulating Materials
    • Transite water supply lines.
  • Electrical System
    • Transite ducts for electrical cable runs
    • Partitions in electrical panels
    • Asbestos cloth to bind bare wires
    • Insulation on stage lighting
    • Mill board templates behind knock-out panels
    • Braided wire insulation on incandescent lighting.
    • Braided wire insulation in older buildings.
  • Exposure to Asbestos
    • Diseases
    • Asbestosis
    • Lung Cancer
    • Mesothelioma
    • Digestive System Cancer
  • ASBESTOSIS
    • A progressively restrictive fibrosis of
    • the lung and is recognized as a
    • disabling and fatal
    • occupational disease.
  • MESOTHELIOMA
    • A rare malignant tumor of the lung
    • membrane which lines
    • the chest and
    • abdominal cavity.
    • Age - cases of mesothelioma have occurred in the children of asbestos workers whose only exposures were from the dust brought home on the clothing of family members who worked with asbestos. The younger people are when they inhale asbestos, the more likely they are to develop mesothelioma. This is why enormous efforts are being made to prevent school children from being exposed.
    Mesothelioma
  • Digestive System Cancer
    • Change in bowel patterns
    • Blood in BM
    • Feeling tired
    • Weight loss
  • B RONCHIAL L UNG C ANCER
    • Malignant tumor of the bronchial tubes,
    • this disease is more common than the
    • other three.
  • Other Cancers
    • Evidence suggests that cancers in the esophagus, larynx, oral cavity, stomach, colon and kidney may be caused by ingesting asbestos. For more information on asbestos-related cancers, contact your local chapter of the American Cancer Society.
  • LATENCY PERIOD (How long it takes to get sick)
    • 10 - 40 years after initial exposure.
  • How Your Lungs Work
    • Defense Mechanisms
    • Exhaling contaminants back out
    • Nose hair
    • Mucous
    • Cilia
                                       
  • Health Hazards of Asbestos and Tobacco
    • Smoking sedates the cilia, disabling one of your key defense mechanisms.
    • A smoker who does not work with asbestos is about 22 times more likely to get cancer.
    • Asbestos workers who
    • smoke are about 80 times
    • more likely to get lung
    • cancer.
  • Hazard Communication
    • Who should you contact when you recognize a damaged condition?
    • What do you tell them when you call?
    • a) nature of damage
    • b) amount of damage
    • c) location of damage
    • d) description of the scene
    • e) occupancy issues

    • AHERA - schools
    • ASHARA - public & commercial buildings
    • NESHAP - air quality districts

  • REMEMBER!
    • Don’t disturb any substance or material thought to contain asbestos.
    • Notify your supervisor if you suspect an ACM has been compromised.
    • Don’t allow high speed buffers to be used on vinyl tile thought to contain asbestos.
    • Don’t allow walls to be disturbed without first notifying Plant Operations.
