Today’s LASER engraving systems are sold as Class 1 enclosed units, and built by the manufacturers to comply with strict regulations as defined by  as defined by  OSHA, (Occupational Health and Safety Administration) ANSI (American National Standards Institute), and CDRH (Center for Devices and Radiological Health).  Laser users and owners are also required by law to comply with certain regulations as well as they relate to the safety of employees, users, and visitors.  Relevant publications, which spell out what is required can be gotten through the Laser Institute of America at  www.laserinstitute.org or 407-380-1553.  Additionally, there might be state and local ordinances which apply.  As with all laws, ignorance is no excuse.

You will also need to be aware that there are dangerous voltages of electricity present within the machine’s electronics and the laser electronics. It is best to unplug the machine if you are going to open these enclosures for any reason.  It is also a good idea to have a fire extinguisher (recommended for electrical fires) close at hand.

The other important safety consideration is to make sure you have an appropriate Exhaust System that is in good working order. This will keep all fumes out of your building and away from employees and/or visitors. Additionally, some materials should not be exposed to a laser at all. Your machine manual will specify some materials that are potentially toxic and/or harmful to your system.  When in doubt about a certain material, ask for a Material Data Safety Sheet form the material manufacturer.  It also pays to experiment by testing new materials prior to large production runs.
