Asbestos Hazards & Lead Based Paint Safety

1
Asbestos Hazards Lead Based Paint Safety

• COMDTINST M6260.16A
• 29 CFR 1910.1025
• 29 CFR 1915.1025
• 29 CFR 1926.62

Asbestos?

• Is a mineral, mined primarily in Africa,
  Brazil, China, and Canada, but is not hazardous
  in its natural state. Asbestos becomes
  hazardous when it is broken up and the fibers and
  dust become suspended in air in the breathing
  zone.

Asbestos Uses...

• Fire proofing
• Can be woven into cloth
• Acid resistant
• High tensile strength
• Excellent insulator

• 1890-1970 -25 million tons used.
• 1930-1941 widest use, especially in shipbuilding.
• 1941-1974 use decreased.
• 1976 all new vessels and constructions asbestos
  free

Three Common Types of Asbestos

• Chrysotile (white asbestos)
• Amosite (brown asbestos)
• Crocidolite (blue asbestos)

• Most common used 95 found in buildings in US.
• Second most likely to be found in buildings.
  (brown in natural state)
• Used in high temperature insulation and
  decorative applications.

5
Common Applications

• pipe lagging
• insulation
• gaskets material
• welders curtains
• sheathing
• floor tiles
• ceiling tiles

• cement
• brake pads
• clutch plates
• spackling/joint compounds
• shingles
• cigarette filters

6
Identification

• Inspections conducted by certified AHERA
  inspectors.
• Laboratory analysis. (only way to prove)

7
Management of Asbestos.

• The Coast Guard mostly manages asbestos in place
  once it has been identified. Only the Yard and
  ISC Ketchikan have trained personnel who can
  conduct asbestos removal projects.
• Most asbestos rehab is contracted out.

8
Hazardous Determination

• Asbestos is only hazardous when it is in a
  friable (breaks easily) state.
• Removal, cutting and other abrasive work can
  release the asbestos fibers.
• Best course of action is to
• maintain in place
• isolate
• encapsulate.
• Removal is only authorized by trained
  professionals or in case of an emergency
  (shipboard only).

9
OSHA Asbestos Standards

• Permissible exposure level 0.1 fibers/cc (8
  hour TWA)
• Excursion limit 1.0 fibers/cc (30 minute sample)

10
Health Hazard

• Asbestosis
• Lung cancer
• Mesotheiloma
• Colon Cancer
• Asbestos and smoking cause a Synergistic effect
• 1 1 10

11
Units Management Plan

• Written instruction/Management plan
• Inventory of ACM or PACM
• Proper labeling of all ACM
• Annual inspection
• Annual Training
• Informing contractors

12
Lead

• Lead is a soft, low temperature melting,
  corrosive-resisting metal used since ancient
  time.
• Has history of documented health effects of over
  exposure for as long as it has been used.

13
Routes of Lead Exposure

• Inhalation
• Ingestion
• Injection

14
Lead Affects

• Blood
• Kidneys
• Nervous System

• Digestive System
• Muscles Bones
• Reproductive System

15
Use of Lead Paint Prohibited
16
Lead Based Paint

• Not written policy but a recommendation
• MLC (kse) can provide guidance.

17
Program Elements

• Written instruction
• Training
• Inventory
• IH sampling
• Medical Monitoring
• Engineering controls
• Signs

18
Protective Clothing

• Coveralls or full body work cloths (Tyvek)
• Hoods/hats (Disposable)
• Boot covers (Disposable)
• Eye protections
• Gloves
• Respiratory protection
