Jim, it appears there are no flow controls installed in the sprayheads or they are installed incorrectly. Without flow controls, the water cannot be regulated into a proper stream flow.
You are correct - drench hoses are supplements to showers *precisely* because they do not deliver 20 GPM.
In fact, Guardian's drench units have the same flow rate as their eyewash units. Drench hoses with the (smaller) GS heads have a 1.6 GPM flow control installed which is a total of 3.2 GPM max. Their drench hose models which have a single larger FS head have a 3.2 GPM flow control, but being single head are simply drench hoses (dual FS spray heads are used on their plumbed eye/face wash models, of course).
The GPM flow rate for these units can be found on pages 8 and 9 of their Guardian’s ANSI guide:
http://www.gesafety.com/downloads/ANSIGuide.pdf Note specifically that they are designed with ANSI requirements in mind: "Controlled, low velocity flow rinses both eyes and is not injurious to user. (Section 5.1.1, 8.2.1)” as well as "Water flow covers area indicated on Guardian test gauge at no more than 8” above spray heads. (Section 5.1.8)" with a diagram showing that the water spray lands on the eyes, not 8 feet away.
The case you report is a great example of why these units need to be tested on a regular basis!

When the drench hose is hand held it is ONLY a supplement for and not a replacement for a hands free safety shower.
With respect to engaging the clip and using this unit for eye wash duty, the are several concerns.
Showers should deliver 20 gal per min. Eye wash is in the 0.4 gal per min. Where are you going to put your face?
I've latched the clip and backed away with a large bucket. The water went about 8 feet. want that force in your eye up close and personal?
