I just think the novelty of these type of displays was up in the 90s, It’s time for an upgrayedd. I propose leprechauns flying up and down the river wearing water jet packs, shooting people with their Chicago-style hot dog cannons would be more with the times. What’s your idea?
It’s wasteful and a bad look, but many things are only hazardous in high concentrations. Even a tanker full of milk getting dumped into a small lake could cause mass die offs. The PPE is probably more about preventing it from being breathed in or getting in their mouths. You can check out the SDS here.
Would any animals in the water not breathe it in or get it in their mouth?
