Putting Out a Laser Cutter Fire

Be alert for a fire in the laser cutter; don't let a small fire become a large one.

Always follow these steps, in order, when attempting to put out a fire in a laser cutter.

1. Lift the Lid
   
   • This will turn off the cutting laser and stop adding heat to the flame.
   • When flame is out, adjust your cut settings, then continue or restart the job.
2. Blow Out the Flame
   
   • If the operator feels safe, attempt to blow out the flame.
   • When fire is out, check with Shop Staff.
3. Power Down
   
   • Close the blast gate to stop air circulation within the machine.
   • Shut off the ventilation if no other lasers are in use.
   • Press the E-Stop – this will turn off the laser and disengage the gantry motors.
   • Move the gantry out of the way to protect the machine optics.
   • When fire is out, see Shop Staff and do not resume work job until cleared by a Staff member.
4. Cover with a Damp Towel
   
   • Use the spray bottle of water to soak a shop towel kept near the laser cutter.
   • Place the damp towel on the flames.
   • When fire is out, see Shop Staff and do not resume work job until cleared by a Staff member.
5. Use the Fire Extinguisher
   
   • Close the lid.
   • Confirm that the ventilation blast gate is closed.
   • Get a fire extinguisher from the wall by the nearest exit door.
   • Push the Emergency Alert Button, or have somebody else push it.
   • Keep the lid closed, and discharge the extinguisher into the front grill.
   • The entire extinguisher does not have to be discharged all at once. Aim, shoot, and evaluate.
   • When fire is out, see Shop Staff and do not resume work job until cleared by a Staff member.
6. Pull the Fire Alarm
   
   • Evacuate the room and the building.
   • Get yourself and any coworkers to the safety master location.
