Abstract
The objective of this program was to develop a basis for assessing the additive toxicity hazards of materials employed in underground coal mining when these materials are exposed to thermal oxidative degradation as would occur before or during a fire. This report covers some of the fire-resistant hydraulic fluids approved by the Bureau of Mines for underground use. The fluids can be divided into five groups or classes as follows: (1) glycol-water solutions, (2) mineral oil-water emulsions, (3) synthetics other than phosphate esters, (4) synthetic phosphate esters, and (5) mixtures of phosphate esters with mineral oils and chlorinated solvents. The pure phosphate esters derived from substituted phenols appeared to be the least dangerous of all the compositions tested even though they evolve toxic phenolic species.
