Yea, never been a big fan of government regulations.

The government knows just enough about things to make it a pain for everybody once they get involved.
If I ever got cancer I would look outside the US for treatment if they ever said it was terminal.

A lack of regulations (building codes) is why 70% of Haiti's buildings in its capital collapsed in their earthquake. Sure, those regulations would've impeded the construction of many of those buildings, but those buildings would probably still be standing.

It's also one thing to injure yourself in the privacy of your own home. It's another to be injured as the result of someone else not following regulations. That's what the regulations are for.

For example, in Moscow in 2008 there was an outdoor rave where there were some high powered lasers at the show. Normally, it would not be an issue, but it started to rain, and the reflections from the raindrops caused back-scattering, permanently blinding some of the people at the event. In such a case, who is responsible? Even if there is someone responsible, does it bring back a person's vision?

In the US, high powered laser beams must be kept far out of reach of the audience (~3 meters minimum). This is to prevent, among other things, some bozo water into the intense beam of a laser, blinding people. Working within regulations to create an awesome show is what lighting engineers are for.

Also think of regulations are a way to reduce your own liability. Compliance ensures that you have followed the guidelines set by an authority. If something goes wrong despite that, you can correctly claim that either the regulations were not sufficient, or that extraordinary circumstances, beyond your control, were responsible for what happened. So if somebody sneaks a supersoaker water gun to your rave, and sprays the beam of a 500mW green laser 4 meters above the audience, blinding people, you're not liable for the results.

you should read up on the Moscow incident before spreading FUD

International Laser Display Association

pulsed lasers should NEVER under any circumstances be aimed at people

but Class IV CW lasers are regularly aimed at people all over the world (yes even illegally in the US - not by me mind you) and there are no other "Moscow" incidents that I am aware of... just go through youtube and look at some of those raves over in Europe... crazy stuff being aimed straight at the audience...

This should be also laser? What do you think?
