He said that one of the men who was working on the battery bank on a sub, was crawling over wooden boards on the batteries to do maintenance. Unfortunately he was not careful and a spanner dropped out of his pocket onto the terminals of the battery. He said that the spanner vaporised and the man was killed. I have had a car battery explode in my face when it was gassing furiously. It was definitely not an experience I would like to repeat. I did see a bank of submarine batteries on charge when I worked at Garden Island Navy Dockyard. They were huge cells. Definitely not something I would want to short out. Still it seems over the top to go out and fine people massive amounts of money. Why not inspect battery banks and educate people. Give them a simple copy of plans to make their batteries safe. Pete
