Training Presentation

Training Presentation

• Asbestos and Lead Awareness
• Prepared by David Olson
• (Environmental Health and Safety Intern)

2
Objectives

• Meet Training Standards described by OSHA for
  Asbestos and Lead

3
Objectives (continued)

• Provide knowledge on
• Typical sources of Asbestos and lead exposure.
• Health effects related to exposure
• What to do if one suspects exposure
• Allow time for review and questions

4
Asbestos Awareness

• Asbestos is a naturally occurring mineral found
  primarily in the mountain ranges of Canada, North
  Central USA (Montana), and northern Eurasia.
  (Magnesium silicate)
• When separated from rock, asbestos becomes a
  fluffy fibrous material that has many uses.
• Properties

Health effects

• Routes of Exposure
• Inhalation
• Mechanism of effect
• scaring of lung tissue
• Diseases
• mesothelioma, asbestosis, or lung cancer
• Latency
• 20 to 40 years
• Why its easy to ignore the danger
• asbestos cannot be seen, smelled, or tasted

8
Health Effects

• From the National Institute of Health
• The combination of smoking and asbestos
  exposure is particularly hazardous. Smokers who
  are also exposed to asbestos have a greatly
  increased risk of lung cancer. However, smoking
  combined with asbestos exposure does not appear
  to increase the risk of mesothelioma.

Safe Work Practices

• Do not sand, grind or pulverize tiles.
• Use wet methods and low abrasion pads slower than
  300 rpm for ACM tiles/floors.
• Avoid burnishing or dry buffing unless there is
  enough finish to prevent contact between floor
  tiles and the pad.
• Do not dust, dry sweep, or vacuum deteriorated
  ACM, unless you are using a HEPA vacuum. Follow
  department procedure (ie use and abatement
  contractor or 16 hour trained individual).
• Asbestos waste is regulated not to be put in
  trash.
• Never use compressed air near friable ACM.

UWSP Asbestos

• If you suspect exposure to asbestos
• Notify your supervisor
• Helpful Resources
• WALMS http//walms.doa.state.wi.us/
• ID UWSP Password 1848
• EPA http//www.epa.gov/asbestos/Asbestos
• UWSP Asbestos Policy
• How does UWSP control exposure?
• Management in Place
• Testing to determine if ACM, if friable, if in
  good condition
• Asbestos Abatement contracting
• Notification to building occupants

11
Discovery of Damaged Material

• If damaged material is observed that may be
  asbestos-containing, the employee should
  immediately report it to his or her supervisor
  and isolate the area with warning tape, pylons,
  etc. Do not touch or disturb the material.
  Immediately contact Facility Services and/or the
  EHS Office. See the UWSP EHS Asbestos Policy for
  more details.

12
Asbestos Review

• What forms of asbestos are (still) banned?
• What behavior poses a significantly greater risk
  for lung cancer when exposed to asbestos?
• How can one learn where ACM is used on campus?
• What are some safe work practices that you can
  incorporate to minimize exposure to asbestos?

13
Lead Awareness

• Lead is a naturally occurring metallic element
  found in the earths crust. Lead can be found in
  many parts of the environment including
  water/soil.
• Lead is highly resistant to corrosion thus was
  utilized widely in the past.
• Properties

Lead Sources of ExposureFrom Safety Orientation
Handbook

• Paints (paint chips)
• Leaded Gasoline
• Drinking water
• Ammunition (lead shot)
• Cheap Jewelry
• Plumbing and solder
• Older pottery
• Lead acid batteries
• Iron and steel production
• Lead contaminated dusts
• Lead smelters (release into air)
• Foods stored in lead crystal
• Folk remedies that contain lead (for upset
  stomach)

15
Regulations on Lead Exposure

• Consumer Product and Safety Commission
• banned the use of lead-based paint in 1978
• Clean Air Act
• Banned use in gasoline in 1990
• Safe Water Act
• Instituted the use of lead-free pipes, solder,
  flux in plumbing operations in 1974
• Community requirements
• Air cannot exceed 0.15 micrograms/m3 (as of
  10/15/2008)
• Drinking water lt 15 ug per L.
• OSHA 29 CFR 1910.1025
• Permissible Exposure Limit is 50 microgram/cubic
  meter for an 8-hour period.

16
Health effects

• Routes of Exposure
• Inhalation and Ingestion
• Mechanism of effect
• The exact mechanism of absorption is unknown
• Transported to other systems in body by the red
  blood cells (RBC)
• Lead interferes with development of hemoglobin in
  RBCs
• Some lead such as in dust, water, and food cannot
  be seen.
• Children absorb lead more easily than adults.
• Children experience more serious health effects
  related to exposure to lead than adults.

17
Health Effects

• Exposure to lead can lead to
• Difficulties during pregnancy
• Other reproductive problems
• High blood pressure
• Nervous disorders
• Memory and concentration problems
• Muscle and joint pain
• Affects almost every organ in body
• Damage to kidneys
• May cause anemia at high exposures

18
Review

• How might a person be exposed to lead today?
• What makes lead more dangerous to children than
  to adults?
• What health effects might a person experience
  from lead exposure?
• How have we reduced to exposure to lead in the
  general population?

• Notify your supervisor
• Get a blood test
