When cutting flammable materials (or non-flammable materials which happen to emit gases which are flammable when cut) or materials with a thin oil/wax film - be prepared for fires or small flames. While not common - it does happen occasionally and should not be cause for panic. When it happens - press the stop button and use a small gentle blast of CO2 fire extinguisher to douse it. There is no need to get very close to the fire - generally the box 'fills' up with the CO2 gas which is heavier than air - esp. when things are not yet hot. Note this in the logbook (both so we can replace the CO2 and because of sooth on the lens). Don't forget to report any fire | When cutting flammable materials (or non-flammable materials which happen to emit gases which are flammable when cut) or materials with a thin oil/wax film - be prepared for fires or small flames.

In the unlikely event that you cannot contain the fire with CO2 - switch to the powder extinguisher. Do not use water (risk of electrical shock). If you use the real (sealed) extinguisher - post an incident follow the accident/reporting protocol - to comply with fire, health and safety regulation. | In the unlikely event that you cannot contain the fire with CO2 - switch to the powder extinguisher.

If you are unfamiliar with fire extinguishers - and why there are many type - then read the instructions on both the CO2 and the ABC extinguisher (http://en.wikipedia.org/wiki/Fire_extinguisher) as to understand the difference. | If you are unfamiliar with fire extinguishers - and why there are many type - then read the instructions on both the CO2 and the ABC extinguisher (http://en.wikipedia.org/wiki/Fire_extinguisher) as to understand the difference. | ||

* Please log your Laser Cutter use in the [http://bit.ly/LaserLogbookForm Lasercutter logbook]. | |||
** This is used to track how long the tube lasts, and if the power levels are dropping, etc. | |||
* Any maintenance will be logged in the [[Equipment/LaserCutter/LogBook|wiki logbook]]. | |||
