Hi Trumps

I don;t have much experience of such battery banks. However I know a gent who used to work in the haulage industry as a fitter. He tells of a chap ( and once showed me a picture of it ) who had been in the firing line when a large tractor battery went up in his face.

Apparently he dropped a spanner on top and shorted the studs. The resulting flash ignited the gas given off as the battery was on a heavy charge. The case exploded and showered him with the contents... Need I say more?

He lost the sight in one eye and his front teeth( actually due to 'shrapnel' ) but most of the skin on his face and chest was melted off. The photo was ghastly. [Linked Image]

You are no doubt completely right to be wary and well protected!

If hindsight were foresight, we'd all be millionaires!
