Health Implications of Diesel Mining Machinery Usage

Government and labor sources have speculated that exposure to diesel exhaust may have adverse health consequences. The purpose of this discussion is to analyze the merits of these statements and place them in perspective to underground mining. It would be ideal to eliminate exposure to all substances until they are proven safe. This is impossible, since nothing can be proven safe. Rather, one must extrapolate by using the best available scientific information to make reasonable judgements and decisions. It makes little sense to ensure that a mine atmosphere maintains a lower concentration of a substance than that allowed for ambient environments. Such regulations are set at more stringent levels than those tolerated in the occupational work place. However, levels of pollutants that are in excess of concentrations tolerated in the work place would not be appropriate in any environment.
