The ANSI/ISEA Z358.1-2004 standard, =E2=80=9CAmerican National Standard for Emergency Eyewash and Shower Equipment=E2=80=9D, states in Appendix B:
B6. Delivered Flushing Fluid. =E2=80=A6..Medical recommendations suggest a flushing fluid at tepid temperatures be delivered to affected chemically-injured tissue. Temperatures in excess of 38 degrees C (100 degrees F) have proven to be harmful to the eyes and can enhance chemical interaction with the eyes and skin. While cold flushing fluid temperatures provide immediate cooling after chemical contact, prolonged exposure to cold fluids affect the ability to maintain adequate body temperature and can result in the premature cessation of first aid treatment. Recent information indicates that a temperature of 60 degrees F is suitable for the lower parameter for tepid flushing fluid without causing hypothermia to the equipment user.
I read that to mean tepid is a range of 60-100 degrees F. At NIST/Boulder, we specify 75-95 degrees F.
