Re: laser safety

I found slightly different info at:

http://www.umr.edu/~ohss/lasers.html

Regarding Class 2 lasers:

-----------------------
2.Class II - Low-Power Visible Lasers

A low-power laser or laser system in the visible range
that may be viewed directly under carefully controlled
exposure conditions. These lasers are considered safe
for exposure times greater than 0.25-second because the
natural reflex motions of the eye will prevent average
exposure from causing damage.

9.General Operation Safety Requirements

B.Class II Equipment

1.Class II low-power lasers shall be marked in accordance
with Section 12.A of this standard practice.

2.The laser beam shall not be purposefully directed toward
the eye of any person.
-------------------------

Based on this you shouldn't aim a class 2 laser at
anyones eyes either (not just 3's and 4's).
