Our company has recently had some drench showers put in, but there is no drainage! I am somewhat astounded at this because I have seen somewhere that you could put 900 ltrs of water through one of these in an emergency.
Visualise it.... a nearly full 1000 litre IBC of water leaking over the floor would be a veritable flood!
Does anyone have any experience of anything similar? what could be done to help to contain and/or collect the water from flooding the floor?
All three are well away from an outside wall and putting in any kind of drainage which would involve drilling or digging up the floor is not an option as it is new build with an extremely hard floor.
Any ideas?

I had this issue in a previous life, no real cost effective solution really and its surprisingly common to install them like this. I had some spill kits on standby near the showers.
The fun part comes when you do a weekly legionella flush check on them without getting wet.

As the clue is in the word "Emergency" if their has been an acid spill on someone and the idea is to drench that person and area with as much water as possible, You wouldn't worry about water Damage or getting the area wet, just like Firemen wouldn't worry about water damage when putting a fire out. As for any weekly tests it wouldn't go amiss if you used a large bucket or container (Plastic oil Drum or water butt) if you feel the need to check it weekly. If you wanted something more permanent toy could use something like a bunded tray to catch the bulk of the water following an emergency http://www.tanks-direct....-Sjc73rs4CFS0W0wodWrkAgA But it might mean a step up and you may have to alter the height of the shower head. But the main priority is to the acid spill and drenching the person involved without too many hurdles in the way.

I had this issue in a former life. When I challenged Estates they said that the British Standard was silent on drainage (doh!).
After a lot of research into what was being used in the area we decommisioned the shower on the following grounds:
a) it had not been flushed in 20+ years
b) no one was using more than a few ml of concentrated acid or other corrosives in that area
c) even if they were, they were most likely to spill it down their legs and a fixed overhead shower was not the most appropriate measure - think how difficult it is the get your upper legs properly wetted.
We replaced it with a hand-held shower located closer to the work, on a flexible hose, which could be taken to a sink nearby, making flushing easy. The shower was fitted to the same pipe so the flow rate was the same. A hand held shower could be directed to the part of the body most appropriate.
I did ask around to find out what experience people had had with these emergency showers in anger and got three responses. Two had had to be treated for hypothermia as being flushed with unheated water for 5 minutes + is a challenge. One finished up with concussion after slipping on the now flooded floor, and ended up with a bigger injury than the acid burn.
Basically I am not against these showers, but you have to bear in mind the quantity of corrosives in use, whether having a shower over the person's head is the most efficient way of washing it off, and where the water is going. I would insist on a drain.
