A fluid composition includes a poly(alkylene glycol) present in an amount of greater than 85 parts by weight based on the total weight of the fluid composition, and a sterically hindered ester present in an amount of from 0.5 up to 15 parts by weight based on the total weight of the fluid composition. The sterically hindered ester, present in the amount of from 0.5 up to 15 parts by weight based on the total weight of the fluid composition, provides the fluid compositions with excellent fire resistance, without adversely affecting other physical properties of the fluid compositions such as hydrolytic stability. More specifically, the sterically hindered ester has a higher fire point (Fp) than the poly(alkylene glycol), which typically sufficiently lowers the S.F.P. of the fluid composition to allow the fluid composition to rate as a Factory Mutual Approved Fluid.
