So, there's a problem here. When you expose human eyeballs to UV light, you risk causing serious damage to your retinas. You won't feel the pain, but you could easily go blind. It would probably take some time, but the damage is cumulative -- a little here and a little there turns into a lot down the road.
So, you need to protect your eyes from potentially damaging UV light when you work with these things. But I don't see any of the models in this video taking care of their eyesight with regards to this product. That's something the manufacturer needs to deal with, unless they want to be the target of Asbestos-scale lawsuits.
