For Guardian Equipment, see https://www.safetyemporium.com/content/guardian/pl-eyewash.pdf for eye washes and https://www.safetyemporium.com/content/guardian/pl-eyeface-2fs.pdf for eye/face washes. These are designed to work with water pressures from 30 to 100 psi, and it would be exceedingly abnormal for a facility to have water pressures outside that range. We've been selling these for 20 years and never had anyone report injuries.I assume a missing flow control could indeed launch water eight feet like Jim reported (hmmm, is an experiment in order?). Just one of the reasons that ANSI Z358.1-2014 requires weekly testing of safety showers, eyewashes, drench hoses, etc.Rob TorekiNIOSH-approved N99 and N95 for $1 or less: https://www.safetyemporium.com/covid/Safety Emporium - Laboratory and Safety Supplies

And "at a velocity low enough to be non-injurious to the user". So the ones you are concerned about are probably not installed per the manufacturer's instructions or the standards.Has anyone ever heard of anyone being hurt by the force of water with these type units?Richard PalluziBE(ChE), ME(ChE), PE, CSP,FAIChEPilot plant and laboratory consulting, safety, design, reviews, and trainingRichard P Palluzi LLC72 Summit DriveBasking Ridge, NJ 07920908-285-3782From: ACS Division of Chemical Health and Safety <DCHAS-L**At_Symbol_Here**Princeton.EDU> On Behalf Of James Kaufman

Subject: Re: [DCHAS-L] New ACS Chemical Safety Videos For College Teaching Labs available on YoutubeMy concern about these units is that the force of the water coming out is too strong.Please use this simple test. Get a large barrel and see how far the water goes. My indoor record is eight feet.Way too strong for your eyes.Solution ... check it and adjust the water pressure.

This unit can be left in the flange for hands-free eye wash use by a single person. A locking clip automatically deploys once the handle is squeezed and after that the user has their hands free to hold their eyelids. Alternatively, the spray heads can be pulled out to drench other parts of the body. For close-up views and more you can check out one of these units on my company=E2=80™s web site: https://www.safetyemporium.com/g5022The mounting position for that unit in the video could certainly be better, as it is positioned rather far back from the edge of the bench and there is an obstruction to the side.Best wishes,Rob TorekiSafety Emporium - Laboratory and Safety Supplies

Only one error: The eye wash in the last video is a two-person operation which doesn't meet the standards. I would talk to Guardian or one of the makers of the types that swing into the sink with a single movement which turns them on and, after that, no hands are required to keep the right amount of water flushing over the eyes while the person uses their hand to hold open the lids of necessary.The narrator is perfect, the subject matter is well organized, the examples are good. I love them with the small exception of the eye wash.Monona
