Electrical safety threads are in many places on the site. Items from GFCS to breaker size to cable size on power strips have been discussed.
I'd like to share a few measures I've taken to make my fish room/building safer for those working on aquariums and living in them.
I've experienced more water-shorts than I want to remember, as have others posting on MFK. I looked around the company where I work (Pulp & Paper industry - lots of water) and made note of the safety measures they've adopted. Aside from GFCS-enabled sockets, in wet areas, the use of environmental water-proof socket covers are widely used.

I was able to find these covers, in bulk, online for about $4 each and installed them on every socket in the hatchery.
And, after having a flame-up on a wet surge protector under a 450 gal, I bought Sockitbox waterproof electrical boxes for all of the multiple connections under my stand-alone aquariums. I installed my boxes above the floor, screwed to the legs/back of the stands ( I placed rubber grommets on the screws when I screwed them in). The cords enter the box on the bottom with slight loop bellies on the cords to prevent water wicking into the box and connections.

I have yet to have an electrical mishap in the last decade since employing these safety measures.
