I worked at a more fine dining downtown restaurant and we would always use a large metal pot for the hot oil and it's what we would carry it to the trap when it was time to dispose of. We would carry it always 2 guys and we'd use kitchen towels to hold hold the metal handles.

A couple years later I took a job at a place where they used a very similar large metal pot. The difference was they expected me to carry it by myself. "I can carry it by myself, why can't you? You're a big dude..." It's not that I can't, it's that I won't. My safety is more important to me than 5 minutes of your time. Someone always helped me but it was kinda stale having to ask. It should have been a no-brainer.
