National Safety Council accident statistics show clearly that miners and mill workers are more likely to be seriously injured or killed than workers in almost any other industry . . . The miner and mill worker is also more likely to catch other lung diseases as a result of his continuous contact with rock dust . . .The record of disease in the mines and mills is a poor one. For these are occupational diseases . . . Although this industry has a high accident and poor disease record, there are no Federal regulations governing its safety and health practices. The history of industrial safety in this country has been one of gradually reducing the high injury and fatality rate as we focus on safety problems in each industry. Our mining injury rate is still, according to the industrial labor organizations, the highest of any of the industrialized nations. It is our responsibility to reduce this accident rate.
