ANSI/ISEA Z358.1 requires the maximum water feed pressure to the unit to be 30.5 psig. 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?

My 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.

If you look at around 2:25 in the video you'll see that's a deck-mounted combination eye-wash drench hose which does meet the ANSI Z358-1 requirement. 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's web site: https://www.safetyemporium.com/g5022
The 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.
Great videos. 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.

FYI, the ACS Office of Safety Programs is pleased to announce that it has published a group of 6 safety videos for college teaching labs. They are each about 7 minutes long and follow the RAMP paradigm to organize the discussion of a variety of lab safety topics.
They are available on the ACS safety Youtube channel. Links to specific videos can be found at
