woodworking safety question

Mar 18, 2016
Hello everyone,
I came here to ask for a suggestion since I know nothing about lasers.

I would like to install two laser lines projectors on a wood processing machine.
I tried with those self levelling laser cross normally available, but the did not have enough power.

I found on eBay this: http://pages.ebay.com/link/?nav=item.view&id=231266501023&alt=web

Which I would like to install. It will be projecting two lines, on a lenght of about 3 meters.
There will be no way to look directly into the laser, but even though the chances are very low, reflections might occur.

Being that the beam will be spread along the lines, could I get away without safety Google's?
Thank you
