You won't hurt them at all. Close studio lights running for an hour might do something. However that very bright light might scare the crap out of them and also temporarily blind them but they'll get over it.

I'm sure there's a tiny bit of bleed off into the near IR and near UV regions, but those would be negligible.
Most electronic flash tubes use xenon, based on this Flashtube - Wikipedia, the free encyclopedia xenon has a spectral peak in violet (UV starts at .4 microns), and probably puts out significant amounts of UV radiation. But the glass used to make the tube can block UV radiation, and usually there is an additional glass lens over the flash tube. For as much as anyone can possibly want to know about flash tubes, check out this site General Xenon Flash and Strobe Design Guidelines A camera flash should have the current density needed to be efficient at 5500 K, and produce a relatively uniform white light at that colour temperature, and would be considered equivalent to blue sky daylight.

now that we've answered the OP's question - what spectrum of light do our flashes emit, compared to sunlight?
Flashes were designed to be used with film designed for use with daylight (as opposed to tungsten film which was designed to offset the greater proportion of yellows, oranges and reds produced by incandescent lighting), so it's probably close to daylight. Film shot with flash seems slightly "colder", so maybe flash biased slightly toward the blue end of the spectrum.

It's roughly the same as daylight, the better the flash unit the closer it is. If you use manual white balance settings for your photography you can generally use the "Flash" preset or the "Daylight" preset interchangeably. Sometimes there is a subtle difference, but once you learn your camera you could well use the slight difference creatively.
