Introduction: 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.
