Is there a standard of any sort for how far a safety shower should be from a (chemical) hazard.

Please don't put "assess the risk" in your response. Incredibly, I have thought of that!

As close as possible, I would have thought.

Speaking from a very recent and unpleasant experience, make sure access is easy.
I know this sounds common sense but when you have a face full of corrosive
substance, making your way to a shower is more difficult than you would ever
imagine.
Once the shower is installed make sure it remains assessible.

Whilst on the subject, can I sugggest all of you out there review your eye
wash provision.
Believe me 2 X 1 litre of eye wash is no where near enough when the time comes.

For info - I am responding to my own post! I have been advised by shower manufacturer JD Hughes that there is no UK standard as such, however they did advise me that

"according to the American National Standard (ANSI Z358.1-1998):Emergency Safety Showers and Eyebath/Facewash units should be installed within 10 seconds reach if an accident occurs, 15 metres (50 ft) away maximum; for strong acids and caustics they must be immediately adjacent to the hazard. Ideally they should be centrally located in a prominent position and not obstructed by heavytraffic or clutter. Panic-stricken persons easily remember such spots. Eye/Facewashunits should be on the same level as the hazard. All units should be clearly labelled with pictogram signs to EC Standard 92/58/E"

Contrast this excellent guidance with the HSE "assess the risk" approach.

Gary,

one issue that I'm sure you have covered with safety showers specifically is to place it away (practically speaking) from the potential exposure area.

last year I audited a site where the shower was placed within an ammonia based and quite confined refigeration plantroom.

You can imagine the scenario.........exposed...........decontaminated ................
.. re-contaminated, we had to ask where the thinking behind this was!
