The British Pneumoconiosis Field Research and new dust standards.
There has been a pressing need to revise standards for permitted concentrations of dust in the atmosphere of coal mines. The National Coal Board’s Pneumoconiosis Field Research, based on regular medical surveys of miners, began in 1952 and has led to the recommendation that there should be no more than 8 mg/m3 of dust in the return air leaving the coalface. This has been approved by the National Joint Pneumoconiosis Committee of the Ministry of Technology, and the new standards came into operation on April I this year.
