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 it’s natural state. Asbestos becomes hazardous when it is broken up and the fibers and dust become suspended in air in the breathing zone.
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 Asbestos Uses...
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. Three Common Types of Asbestos
pipe lagging insulation gaskets material welder’s curtains sheathing floor tiles ceiling tiles cement brake pads clutch plates spackling/joint compounds shingles cigarette filters Common Applications
Identification • Inspections conducted by certified AHERA inspectors. • Laboratory analysis. (only way to prove)
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.
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 trainedprofessionals or in case of an emergency (shipboard only).
Health Hazard • Asbestosis • Lung cancer • Mesotheiloma • Colon Cancer • Asbestos and smoking cause a Synergistic effect • 1 + 1= 10
Units Management Plan • Written instruction/Management plan • Inventory of ACM or PACM • Proper labeling of all ACM • Annual inspection • Annual Training • Informing contractors
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.
Routes of Lead Exposure • Inhalation • Ingestion • Injection
Blood Kidneys Nervous System Digestive System Muscles & Bones Reproductive System Lead Affects:
Lead Based Paint • Not written policy but a recommendation • MLC (kse) can provide guidance.
Program Elements • Written instruction • Training • Inventory • IH sampling • Medical Monitoring • Engineering controls • Signs
Protective Clothing • Coveralls or full body work cloths (Tyvek) • Hoods/hats (Disposable) • Boot covers (Disposable) • Eye protections • Gloves • Respiratory protection
