That is consistent with the 2009 version of the standard.  Their definition
states:   "A flushing fluid temperature conducive to promoting a minimum 15
minute irrigation period.  A suitable range is 16-38 degrees C (60-100
degrees F)."

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

B6.  Delivered Flushing Fluid.  É..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.

All:  I vaguely remember a discussion somewhere about what temperature the
water should be mixed to in eye wash stations.  Could anyone tell me that
this is?
