Safty equipment for etching

Hi everyone!

Iv been reading loads of old posts about etching and the different solutions and where to get them from (if anyone else has anymore recommendations let me know), but I was hoping to find out more about the equipment you use.

Such as… what to put it in, do you need a specific glass tank or will an old casserole dish do?

If I use Ferric nitrate and I work outside, do I need a respirator as well?

What do I put the solution in when I’m not using it or does it need to be disposed of right away?

Thanks in advance
