There’s an overpass downtown next to my office. Whenever I walk under it, I notice that there is a 10 foot tall plastic tank in a little fenced off area under the overpass next too the sidewalk. The fenced area has the little emergency shower and other safety precautions. The tank is labelled “Hydrogen Peroxide” and has the little chemical warnings.
I am assuming that the tank belongs to the DOT but why do they need Hydrogen Peroxide in bulk and why must it be right there rather than in a more secure location?
When I saw the thread title, my first thought was “To dissolve away any food that gets caught under it.”
But after reading the OP, that doesn’t seem to be correct (although it conceivably could be, I guess).
I have no idea
In Hollywood they assure that new arrivals become blonde. ;->
If it really does belong to the DOT, maybe they are using it to clean off bird droppings so they don’t rot the bridge metalwork.
I know, I know…no WAGs in GQ. Sorry.
Educated guess:
Besides removing stains, Hydrogen Peroxide is used to remove molds. I have heard that road crews use bleach to kill mold on cement bridge underpasses, but I think another option would be to use Hydrogen Peroxide.
I found a couple of online articles saying that HP could be used to clean up graffiti as well as mold and algae.
