Battery relocation- Does anyone know of an actual hydrogen sulfide explosion incident?

Had one go off in my face after we charged the battery and then took a terminal off to troubeshoot a short, I got lucky for sure, was back in the early 80's no eye wash stations back then just a slop sink.

if it was like my incident with two b-52 batteries in the A.F. , the mop sink didnt help much !
