The ANSI/ISEA Z358.1-2004 standard, =93American National Standard for Emergency Eyewash and Shower Equipment=94, states in Appendix B:

=A0

B6.=A0 Delivered Flushing Fluid.=A0 =85..Medical recommendations suggest a flushing fluid at tepid temperatures be delivered to affected chemically-injured tissue.=A0 Temperatures in excess of 38 deg rees C (100 degrees F) have proven to be harmful to the eyes and can enhanc e chemical interaction with the eyes and skin.=A0 While cold flushing fluid temperatures provide immediate cooling after chemical contact, prolonged e xposure to cold fluids affect the ability to maintain adequate body tempera ture and can result in the premature cessation of first aid treatment.=A0 R ecent information indicates that a temperature of 60 degrees F is suitable for the lower parameter for tepid flushing fluid without causing hypothermi a to the equipment user.

=A0

I read that to mean tepid is a range of 60-100 de grees F.=A0 At NIST/Boulder, we specify 75-95 degrees F.
