Two studies were conducted in the coal mines to evaluate worker exposures to a dust, and the effectiveness of airpurifying negativepressure half mask respirators and was found that miners'' protection were insufficient. An elastomeric and filtering halfmask negative pressure respirators with (midefficiency) filters P2 (FFP2) were studied.
Coal mining remains a sizable industry, with millions of working and retired coal miners worldwide. This article provides an update on recent advances in the understanding of respiratory health issues in coal miners and focuses on the spectrum of disease caused by inhalation of coal mine dust, termed coal mine dust lung disease.
In view of this, we are concerned that the statement "Respiratory protective equipment should be used as a primary means of protection" could inaccurately be taken out of context. Use of respiratory protection should not be a primary means of protection against respirable coal mine dust, for the reasons provided subsequently in the Review.
