Steps To Put Out A Laser Cutter Fire

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

Lift the Lid

• This will turn off the cutting laser and stop adding heat to the flame.

• When the flame is out, adjust your cut settings, then continue or restart the job.

Blow Out the Flame

• If the operator feels safe, attempt to blow out the flame.

• When the fire is out, check with Shop Staff.

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 until cleared by a Staff member

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 until cleared by a Staff member.

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 until cleared by a Staff member.

Pull the Fire Alarm

• Evacuate the room and the building.

• Get yourself and any coworkers to the safety master location.
