I watched a guy try to use a regular grinder wheel on a stainless weld yesterday

He was working on a 3 inch stainless pipe at the yard, and I saw him grab a standard carbon steel cutting wheel. I told him he needed a stainless specific one to avoid contamination, but he just shrugged and kept going. That's how you get rust spots and weld failure down the line, right? How do you guys make sure new helpers get this stuff before they start?

I just keep the stainless wheels in a different color bin, like @the_thomas said.

Yeah that's a classic way to ruin a stainless job lol. Seen it cause rust streaks and weak spots more times than I can count. Best thing is to just show them the right wheel and the wrong wheel side by side when they start. Tell them straight up that using the wrong one puts carbon into the stainless and wrecks it. If they keep doing it wrong after that, they shouldn't be touching stainless, period.

So what's the next step, do we just start hiding the steel wheels and pretending they don't exist? Like a shop-wide game of keep-away for grown adults who can't follow basic instructions?
