- | Fire extinguishers are an absolute necessity. Not only can the materials being etched catch fire, but the gases released can ignite as they pass through the laser beam. Epilog recommends CO2 fire extinguishers because they do not contain chemicals that would be harmful to the mechanics or optics of the system. CO2 fire extinguishers have the added benefit of being easily refilled, available used and inspected from licensed fire extinguisher service companies, and fun at parties. Ghost marking picked up two 5lbs CO2 fire extinguishers for $65 each from: | + | Fire extinguishers are an absolute necessity. Not only can the materials being etched catch fire, but the gases released can ignite as they pass through the laser beam. <del>Epilog recommends CO2 fire extinguishers because they do not contain chemicals that would be harmful to the mechanics or optics of the system.</del> Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics (the stuff you're most likely lasering that could catch fire). CO2 fire extinguishers don't work very well on class A fires because they may not be able to displace enough oxygen to put the fire out, causing it to re-ignite. Remember, Carbon Dioxide (CO2) extinguishers are used for class B and C fires. |

+ | **Epilog recommends a Halotron fire extinguisher or a multi-purpose dry chemical fire extinguisher**. The Halotron extinguishers are more expensive than a dry chemical, but offer certain advantages should you ever need to use an extinguisher. The Halotron extinguisher discharges a clean, easily removable substance that is not harmful to the mechanics or wiring of the laser system. The dry chemical extinguisher discharges a sticky, corrosive powder that is very difficult to clean up. | ||
+ | |||
+ | That said, Halotron fire extinguishers have fallen out of favor for other "clean agent" fire extinguishers that are not "ozone depleting". These alternatives are even more expensive, which is why finding a used (re-certified) Halotron I extinguisher may be your best bet. | ||
+ | |||
+ | While CO2 fire extinguishers have the benefit of being easily refilled, available used and inspected from licensed fire extinguisher service companies, and fun at parties - they are not recommended for protecting your laser. | ||
