I came aross a battery hazard I hadn't thought of before. I asked one of my team members to remove the pigtails (power cable and plug) from an old battery. I'm sure the battery still had charge to it.

She enterprisingly recruited another team member to help, and I saw that each had a wrench on the battery - one on the positive erminal and one on the negative. I immediately asked them to stop. If there's a wrench on each terminal, and the wrenches touch one another, they will short the battery!! Any piece of metal will conduct electricity, not just a wire and not just copper.

FYI, I could envision this happening, especially in a pit if two people change or just tighten connections and are in a hurry. Only one wrench on a battery at a time!
