Fail safe? How do you figure?

Thanks for your comments to the various questions.

Maybe my English impression was poor.
With fail safe I was meaning the safe construction which is controlled by
regulations and paragraphs.
In outdoor use and in moist places standard fluorescent tubes, their wiring,
chokes and igniter are never allowed to have open construction. (at least
here in Nordic countries)
Similar situation is not with neon lights on the walls. Sometimes there are
bare without any enclosures.
I even remember having seen the end wires of the tubes visible.
Well - normally neon lights are rather high so that people cannot touch
them.
