I only electroplate in my garage with all the doors open and a fan running. Always wear rubber gloves (the disposable kind) and eye protection.
Keep a container of fresh water near by when your electroplating (not a sink with faucet, too much splattering) and dip everything you plate in the fresh water before allowing the metal to dry (on folded paper towels).
I tend to plate a number of parts at a time, rinsing my gloved hands in the container of fresh water after each piece is done. This prevents transfer of acid to anything.
Have a large clock with second hand visible. Too long a bath in the plating tank ruins the surface of the metal and you will have to remove and start all over again.
Typically I do plating on a plastic table with paper towels spread out to catch any drips or splatter. Stay away from your work bench and all tools.
I store the entire collection of funnels, plastic containers and battery/ clamps in a cardboard box away from everything else. It’s on the concrete floor in case of leaks or spills.
Have a collection of different size plastic containers for use only for this process. Small and medium. I also have a plastic tray from a tool box that I use for long narrow pieces (like the metal seat runners under the seats).
I’ve tried wiring multiple pieces together to make the plating process go quicker. It’s not very effective as voltage drops along each piece and the plating is at different stages. I think I would need a more controlled voltage supply than 2 C batteries. It looks like you have that, but keep that device far away from the chemicals or your gloved hands that will transfer chemicals.
There is a metal polish your supposed to use after plating to brighten it up. I rarely use it as most pieces are not getting a lot of visibility and it’s a lot more work.
Once you get the hang of it everything goes quickly. As you have seen with me, I plate on a moments notice as it’s fairly easy. Just make sure you are always aware your dealing with acid and need to be careful all the time.
