MIOSHA-STD-07-1R4
April 12, 2018
Eyewash/Shower Equipment page 4
XIII. Application of Standards
B. The terms suitable facilities, quick drench showers, acceptable facilities,
appropriate eyewash facilities, emergency shower and eye-wash station, eye wash
station, and facilities, as utilized in any of the specified standards/rules, shall be
defined as a plumbed or self-contained emergency shower and/or eyewash
equipment, or eye/face wash equipment, meeting the engineering design
specifications of the American National Standard for Emergency Eyewash and
page 5
Shower Equipment (i.e., ANSI Z358.1 - 2014). This Instruction relies on ANSI
Z358.1 - 2014, to determine how quickly the control valve must be operated.
ANSI states that activation of the eyewash control valve shall occur in 1 second or
less and be simple to operate. MIOSHA has made a clarification that more than
one motion to activate the eyewash is permitted as long as the activation occurs in
one second or less. A second/separate motion to remove nozzle covers is not
allowed.
Note the "shall" for the actual equipment. And the new fact sheet covers the other issues and it now reads:
https://www.michigan.gov/documents/dleg/eyewash_292559_7.pdf Revised 06/21/18
What does "suitable facilities" mean?
The terms suitable facilities, appropriate eyewash facilities, and other such terms that appear in
various MIOSHA standards/rules, can be met by following the ANSI (American National Standard
Institute) standard for Emergency Eyewash and Shower Equipment (Z358.1 - 2014).
The emergency eyewash/shower must be activated within 1 second and must not require a separate
action to remove covers. Many eyewash covers are pushed off/open by water pressure. Ensure
employees are properly trained in the operation and activation of the eyewash/shower and that activation occurs in 1 second or less.
and
Does MIOSHA require the supply of tempered water at plumbed eyewash and safety showers?
MIOSHA standards do not require any specific temperatures. However, implied in the term "suitable facility" is providing a water temperature that is not too cold or hot. ANSI Z358.1 - 2014 recommends that tepid water (temperatures between 60 =B0-to-100 =B0 F) be supplied. Temperatures below 60 =B0 F may cause the employee not to use the facility long enough (15-minutes). Temperatures above 100 =B0 F may be too hot and enhance chemical interactions with the eyes and skin.
and
Does MIOSHA require testing of such facilities?
MIOSHA standards do not specifically require
testing of plumbed emergency eyewashes or safety
showers. Follow the manufacturer's
recommendation for testing. ANSI Z358.1 - 2014
specifies that testing of such equipment be
performed on a weekly basis. Remember that these
facilities are provided for "emergency use." Testing
is necessary to ensure that facilities perform per the
manufacturer's specifications.
Looks like a done deal in Michigan to me. Lord, Nice to know some safety agency is still working in the country.

Subject: Re: [DCHAS-L] Emergency Shower and Eyewash Temperatures
Note that the same ANSI standard that recommends tepid water also recommends weekly testing. Like OSHA, our state MIOSHA doesn't "require" following the ANSI standards, but makes it clear they expect it as seen in these excerpts from the "MIOSHA Fact Sheet, Eyewashes and Safety Showers":
NOTE when reading these that failure to provide a suitable facility can be deemed a violation.
What does "suitable facilities" mean?
The terms suitable facilities, appropriate eyewash facilities, and other such terms that appear in various MIOSHA standards/rules, can be met by following the ANSI (American National Standard Institute) standard for Emergency Eyewash and Shower Equipment (Z358.1 - 2004). [Note, I've deleted two sentences because they are changing the definition of when they are required and distance from hazard; the new requirements now mirror the ANSI standard] The ANSI standard also provides eyewash/shower specifications, inspection requirements, and other important elements.

MIOSHA standards do not specifically require testing of plumbed emergency eyewashes or safety showers. However, ANSI Z358.1 - 2004 does require the testing of such equipment on a weekly basis. The pertinent point to remember is that such facilities are provided for "emergency use." Facilities that are not routinely tested may not perform per the manufacturer's specifications and deliver uncontaminated water. This can result in the employer failing to provide a "suitable facility" and more importantly leave employees unprotected.

Mr. Towle,
Back to the original question: "Are there any regulations surrounding eyewash and emergency shower temperatures?"
The answer is No.
OSHA (the regulatory body in our case) has a regulation at 29 CFR 1910.151(c) which requires eyewash/showers to be available where employees can be exposed to chemicals hazardous to the skin or eyes. Nowhere in this rule is a temperature range specified for the water.
OSHA often refers to ANSI [Z]358.1-2004 which does specify a temp range of 85 to 100F, but this is guidance only - not enforceable.
Guidance is good though, because if your employee has to use an ice cold or scalding hot eyewash/shower, your insurance company will be much displeased and their lawyer will be dancing all the way to the bank.
I hope this helps. Good luck.

Thank you for your input, everyone! This is a lot of great information for me to use moving forward.
Upon further inspection of our setup, there is a single mixing valve beneath each handwashing sink that feeds both the sink and the emergency eyewash. Has anyone encountered this configuration before? To me, it seems that there should be a separate mixing valve for the handwashing sink and the eyewash since they have different temperature requirements.
Anyway, thank you, again!

Also, remember that mixing valves fail. I have had situations where mixing valves that served all of the units on a floor have failed on the hot side, resulting in a complete system having water above 120F. We have asked our Facilities group to ensure the valves are part of the building preventative maintenance plan after we had to rebuild or replace a number of them.

Hi All,
This is so weird because this exact thing happened in one of our newly renovated labs. A few weeks ago I was instructing students on flushing eyewash and safety shower and noticed the shower was scalding hot. The eyewash/shower had been installed last summer and has been fine all year. I checked a second system in that lab only to find that the shower was not functioning at all. It turned out that someone (contractors remodeling a restroom perhaps?) had erroneously turned off the cold water valve that feeds the emergency equipment. That caused scalding water at one end of the room, and no pressure at the other. The eyewash and shower are fed with water from a mixing valve.
This is why we check!
Best,

Hello everyone,
This may seem like a basic question, but I am getting some pushback from our plumbing contractors on this.
We have a brand new facility and I went through to test all of the eyewash and emergency shower stations. At first everything seemed to be working fine, but then I noticed that the emergency eyewash water was getting warmer. I was horrified when the eyewash water became hot. I have never encountered hot eyewash water before. I had the contractors re-plumb the eyewash stations into cold tap water only. Now they are pushing back, wanting to hook the eyewash stations back into the hot water.
I also noticed that our emergency shower is releasing hot water.
Are there any regulations surrounding eyewash and emergency shower temperatures? My understanding has always been to have cold, potable tap water running into emergency showers and eyewashes so that chemical reactions are not accelerated upon exposure to heat. Regardless, with the temperatures that our eyewash stations were reaching, there was no way that anyone could keep their eyeballs open for 10 minutes in this water. Any information is appreciated, especially information that will put this debate to rest.
Thank you!
