Laser equipment if used incorrectly may cause damage to not only your eyes but those of people working with and/or around you. We recommend that lasers be used with great care and urge users to make sure that their work environments are as safe as possible for both themselves and the public. Below are some simple guidelines;

DO NOT look directly at the laser beam
WARN passers by or onlookers of the laser’s presence
USE laser safety warning signs (see examples below) 
TAKE CARE where you place and aim your laser

Ultimately if you are sensible with your laser equipment and read the manuals provided with your laser; you should enjoy a trouble and injury free work environment.
