The Documents Will Reflect:
The industry knew long before men and women were exposed that Asbestos, Benzene & Vinyl Chloride caused injuries to humans that could be FATAL!!!!
“The number of men employed in trades and industries involving exposure to asbestos dust in the United States is unknown….There are numerous processes involving the conversion or remanufacturer of the materials which are distinctly more serious in their effects on health and longevity.”
|Frederick L. Hoffman Medical Statistician Prudential Life Ins. Co.||“All of these processes unquestionably involve a considerable dust hazard, but the hygienic aspects of the industry have not been reported upon. It may be said, in conclusion, that in the practice of American and Canadian life insurance companies asbestos workers are generally declined on account of the assumed health-injuries conditions of the industry.”|
“There are four effective methods that may be used to prevent the
inhalation of dust generated during industrial processes. No one of these
can apply to all conditions, but the particular method to be used must be
adapted to the peculiarities of the process.|
|(1)||The use of water to dampen the dust and thus prevent it from rising and filling the atmosphere.
|(2)||The use of exhaust systems which remove the dust at the point of
|Louis I. Dublin, et al
|(3)||The use of enclosing chambers in which the dust-producing
processes are confined, being regulated from the outside.|
|(4)||The use of respirators and helmets.|
|Health Hazard||Symptom, condition, or disease to look for||Occupations which offer such exposure|
|1. Inorganic dust…..||Cough, dyspnea, pleuritic pains, hemoptysis, clubbed fingers, marked flatness of chest, deficient expansion (unilateral), dullness, diminished resonance, mucous, rales, fibrosis… pleurisy, tuberculosis…||asbestos workers|
“While carcinogenic properties are generally associated with certain polynuclear aromatics and their derivatives, there are many substances entirely unrelated to these compounds which have been reported as having similar cancer-producing ability. Among these may be mentioned asbestos……and a number of nitrogen compounds, most of which contain one or more benzene rings.”
26 years before this picture, Louis Dublin explained 4 ways to prevent the inhalation of dust generated during industrial processes.
“Benzene is a clear, colorless liquid with a characteristic pleasant odor at low concentrations and a disagreeable odor at higher concentrations….
Continuous exposure to benzene over a 20 year span can result in chronic benzene poisoning.
... 2. Chronic Effects
“Benzene is relatively insoluble in body fluids and tissues; therefore, only small amounts are absorbed by the body.”
“There is no single change in the blood or blood-forming organs which is universally present in benzene poisoning.”
“The bone marrow where blood is formed may be hypoplastic, fairly normal in appearance, or hyperplastic. Abnormal forms or young cells may abound, and reasonably well document instances of the development of leukemia as a result of chronic benzene exposures have been cited.”
3. Safe Limits
Inasmuch as the body develops no tolerance to benzene, and as there is a wide variation in individual susceptibility, it is generally considered that the only absolutely safe concentration for benzene is zero.”
“Recent evidence has pointed out a definite correlation between cancer incidence and exposures to ultra-violet radiation, asbestos, benzol, certain incidence and exposures to ultra-violet radiation, asbestos, benzol, certain organic amines, paraffin oils, as well as heavy petroleum distillates and degradation products such as tars, cokes, and pitches.
Berry further reports, “Initiate preventive measures as soon as possible since the identification of the offending agent is not necessary. Industrially, the approach would be as follows:
a) Through technical control aim at the complete elimination of the exposure, or,…..
e) Instruct the workers in the proper use of the protective measures provided and tell them why their cooperation is required.
6) Medical control programs must be set up, not only for current diagnosis and
treatment, but aimed at following the worker throughout a latent period which may extend for 15-20 years.
Hine attaches a table that identifies “the known or commonly suspected chemical agents causing cancer that are present in the oil industry…..

Tells Pittsburgh Corning about health hazards from asbestos exposure including asbestosis and carcinoma of the lungs and pleura is published in 1954. Pittsburgh Corning then purchases the asbestos containing insulation product line called Unibestos and continues to sell the product with no warnings.

Q. Was there ever a time when Shell didn’t tell employees about carcinogens?
A. We’re in trouble now.
