What is Asbestos • Once known as the “Miracle Mineral” • Now one of the most widespread contaminants on earth Hansen – Managing Safely
“Miracle Mineral” • Low Thermal Conductivity • High Temperature Resistance • High tensile strength • Low electrical conductivity • Chemically inert Hansen – Managing Safely

History Import of Amphibole Asbestos Hansen – Managing Safely
How long have we known? • 1890 Asbestosbecomes a new raw material for large manufacturing industries. • 1918 Prudential insurance internal memo notes life insurance not to be given to asbestos workers. • 1930 Johns-Manville internal memo identifies a large fatalities amongst asbestos workers. • 1932 letter U.S bureau of mines to asbestos manufacture Eagle-Pricher “It is now known that asbestos dust is one of the most dangerous dusts to which man is exposed.

When asked “do you mean to tell me that you would let them work till they drop dead” his response was “yes. We save a lot of money that way”. Hansen – Managing Safely
1951 Results published with all references to cancer removed. 1964 Toxicological study identifies abnormal results. 1969 Voluntary ban on Crocidolite. 1985 Amosite & Crocidolite. 1999 Chrysotile Ban. Hansen – Managing Safely

Health Effects • Asbestosis • Mesothelioma • Lung Cancer • Pleural Plaques • Throat and Nose Cancers • Cancers of the Digestive Tract Hansen – Managing Safely
Asbestosis • Reduced lung capacity • 10 years + to develop. • Treatment will slow • down but not halt. • Often result in death • through heart problems. • Approx 300 deaths P.A, • and decreasing Hansen – Managing Safely
Lung Cancer • Similar to Tobacco L.C. • Operable in very early • stages. • Appears 10-15 years + • after first exposure. • 90% die within 5 years. • Approx 2500 deaths P.A Hansen – Managing Safely
Mesothelioma • Extremely painful • death. • 25-30 up to 50 years • after exposure. • 1500 deaths P.A. • Life expectancy 9 – • 18 months. Hansen – Managing Safely
