There are some devices with mercury vapor lamps for applications that require a broader spectrum. True though that LED have mostly just one peak and then open up in visible wavelengths again.
Theoretically it should be safe, but I would still use glasses, since even outer layers of your eye are probably photosensitive, not only your retina.
But yes, UVA specifically is dangerous for skin too, since it travels deeper without causing sunburn symptoms but still damaging the tissue, so a shorter wavelength might even be preferable.
