Eyewash stations are required to have correct signage and be well illuminated. I ask if that switch is to the source of that illumination; you shouldnt have to fumble with a switch to use a shower.
There does not appear to be any OSHA violation with a switch (of any voltage) being that close to the shower, tho I did find this from John Hopkins Hospital:
Location:
Shower located in an area that requires
no more than 10 seconds to reach.
In a well-lit area and identified with a sign
and
4. No obstructions, protrusions, or sharp objects shall be located within sixteen (16) inches from the center of the water spray pattern of the emergency showers or within six (6) inches from the center of the water spray pattern of the eyewash station
5. No electrical apparatus, telephones, thermostats or power outlets shall be located within eighteen (18) inches of either side of the emergency shower or eyewash

If the switch is 2' away, it's okay. Davebones wrote in his first post it's "about 2 ft" away. JHU isnt OSHA, the NEC, or AHJ, however, that they include the information I cited above in (4) and (5) means someone is thinking about it and concerned enough to make it policy.
Sprinkler heads are off topic; we could discuss that elsewhere if you wish.
