Abstract : A generator was developed for examination of the potential adverse health effects of respirable size aerosols of hydraulic fluids under high pressures (1 000 to 1500 psi) released through micro-orifice pin-hole (2.03 X 10 2 cm diameter) breaches in the hydraulic system. Tests with the oil-in-water emulsion hydraulic fluid designated as HS 5047F, used in Naval systems, demonstrated that at various fluid pressures respirable size aerosols (ranging from 2.8 to 4.2 micron mass median aerodynamic diameter) can be delivered at concentrations up to 163 mg/m3 and higher, given the appropriate conditions. A series of mathematical expressions was developed to predict aerosol droplet size as a function of nozzle orifice diameter and physical characteristics of the test fluid such as viscosity, density, and surface tension.
