How long have we known?How long have we known? 1890 Asbestos becomes 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.


•1933 29% of John-Manville’s plant have asbestosis.

•1936 group of asbestos companies sponsor research into the effect of asbestos but demand control over disclosure of information.

•1942 John-Manville president says that managers of another asbestos firm were “a bunch of fools for notifying employees who had asbestosis”. 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”.


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.

Health EffectsHealth Effects


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


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


MesotheliomaMesothelioma• Extremely painful

death.

• 25-30 up to 50 years

after exposure.

• 1500 deaths P.A.

• Life expectancy 9 –

18 months.
