The outgassing characteristics of single samples of three classes of Navy hydraulic fluids were investigated in order to help establish a basis for determining the potential toxicity of resulting gases in ship's atmospheres. Hydraulic fluids studied were: neopentyl polyol ester (MIL-L-23699B); triaryl phosphate (experimental); and petroleum base hydrocarbons (MIL-L-17331F). The samples were sequentially exposed to temperatures of 50, 100, 250, and 450 Cel each for 3 hours, and the types and amounts of the outgassed products were determined. The neopentyl polyol ester hydraulic fluid emitted large numbers of caron monoxide, aldehydes, and nitrogen oxides at 25 Cel, and above. The triaryl phosphate hydraulic fluid emitted amounts of carbon monoxide, nitrogen oxides, and aldehydes in excess of the threshold limit value only when heated to 450 Cel. It contained a large amount of a phenol-type constituent. The petroleum base hydrocarbon hydraulic fluid emitted carbon monoxide at 250 Cel and above and aldehydes at 450 Cel in excess of threshold limit values. Of these emissions, the carbon monoxide and aldehydes from the neopentyl polyol ester and the phenol-type constituent from the triaryl phosphate are the most potentially hazardous. (Jensen)
