Blue polypropylene elbows reef safe?

[Z Burn's Reefing]

Hi all, I picked up some barbed elbows from Home Depot that are blue polypropylene. Need them for my UV sterilizer. Didn’t think much of it but brought them home and see the California cancer warning on the label, and now I’m asking myself… are these reef safe? I always assumed polypropylene was a safe plastic and food grade but the cancer warning is throwing me off…

Polypropylene is generally reef safe.

I expect it is reef safe despite the "warning".
