Subject: Re: Definition of "tepid"
div style='font-family: Arial; font-size: 12pt; color: #000000'>Be really
careful with this one...
California does not enforce the current ANSI s
tandard (Cal/OSHA's current Standard refers to ANSI Z358.1-1
981 and there is no mention of the word "tepid").
- Higher water temperatures can sometimes exacerbate the ef
fect of a chemical exposure to the eyes
- Mixing valves do not necess
arily deliver "tepid temperatures" right away; they can also fail and if ey
ewash water is not on a dedicated circuit, other influences can affect temp
- Weekly / monthly inspections, to be effective under the tep
id rubric, must include a temperature monitoring parameter... consider how
to implement that requirement to make it meaningful...
So here's a question: How many of you have actually "washed you
r eyes" for even just a few minutes using the pre-tepid systems? If n
ot, you may want to try it! From one who has (as a test, not a necess
ity and over a sink with a drain), it's not that bad and I readily understo
od the need for "hands-free"devices: holding one's eyelids open and grittin
g down (make a wooden "chomp" dowel available?) does work and my eyes got u
sed to the temperature within a minute or two.

60 F may be too cold and hypothermia could still be a concern
for extended washing. However, 100F is just above body temp, it should be p
retty good for an eyewash.

I know we=E2=80=99ve beaten this one to death already but I wasn
=E2=80=99t paying attention and now I need the collective brain. I fo
und ANSI says that "tepid=" is between 60 and 100F. Bu
t I seem to recall other advice that suggests this is too wide of a range
=E2=80=93 60F is uncomfortably cold and 100F is far too hot for an eyewash.
