Abstrakt: A low-temperature version of MIL-H-83282 (LT 83282) is a candidate hydraulic fluid to be used as a replacement for the current low-temperature fluid used on Strategic Air Command aircraft. A single neat dose of 0.1 mL LT 83282 into New Zealand White (NZW) rabbit eyes resulted in slight conjunctival irritation for up to 24 hr after treatment in two of nine rabbits. Rinsing the eyes after treatment appeared beneficial. A single treatment of 0.5 mL neat LT 83282 to rabbit skin produced no irritation. A total of 40% of the guinea pigs receiving repeated dermal application of the fluid demonstrated a positive sensitization response. A single oral dose of 5 g LT 83282/kg body weight given to five male and five female Fischer 344 (F-344) rats and a single dermal application of 2 g LT 83282/kg body weight applied to five male and five female NZW rabbits resulted in no deaths. Inhalation exposures to aerosol concentrations of LT 83282 resulted in an LC50 of 2.13 and 1.50 mg/L for male and female F-344 rats, respectively. No clinical signs of acute delayed neurotoxicity were observed in hens twice dosed at limit levels (5 g/kg) and observed for 21 days.
