Now I have remembered that in 1961 between school and college I had a
holiday job with Radford's in Bristol, UK, who made PA amps for
supermarkets. (Quite a new idea, then, perhaps.) Their snooty designer,
fully suited, came to review the first of his new design off the
production line, and I was one of the erks in attendance. As he bent
over it to inspect our workmanship a large electrolytic exploded and
decorated him with confetti. There were a lot of badly bitten lips and
choked-off splutters...

So I am familiar with the danger, after all!
