Are these safe for water mixing station?

[benjammin03]

I have been looking for some brute trash cans for a water mixing station, but I came across these for a lot less. I'm guessing they probably aren't water safe, but does anyone know for sure? It seems like a great price if I can use them.

I don't know if those are food safe or not but there are typically 55 gallon plastic barrels or drums for sale on Craigslist that are food safe.

I use RK drums for my water change station as well. Just make sure to rinse them out with a bleach solution and rinse them very well also.

To make sure plastic buckets are food safe, check the number inside the recycling symbol. If it is a 1,2,4, or 5 then it is food safe. 2 is the best number. Source

I have these.
Mine looked like they just came from the factory

Didn't even need to rinse
