*Fire: Be sure to always be in clear view of the laser cutter as fire is a very real and dangerous reality. If there is a significant fire, press the small “STOP,” then “DATUM” button on the software and put out the fire with one of the 2 CO2 fire extinguishers available. Be sure to familiarize yourself with where the “STOP” button and the “DATUM” button is on the machine and software, respectively. For a small fire, you can try to blow out the flame.

*Do not use any material that might have chlorine. You can check by heating a copper wire in a flame, touching the material, and then reheating the copper wire. If the flame emits a green colour then there is chlorine in the material.  ([[https://vimeo.com/1615418|https://vimeo.com/1615418]])
