Things You'll Need

Instructions

1

Keep a fire extinguisher made specifically for electrical fires within easy reach of the computer. Ideally, this should be a Halotron I extinguisher. While expensive, it is made particularly for computer rooms and other electronics areas.
2

Fight the fire only if it is small and contained. Otherwise, evacuate the building along with everyone else and call the fire department.
3

Close all doors entering the room where the computer fire is burning.
4

Use the acronym PASS when putting out a fire--pull, aim, squeeze, sweep. Pull the pin on the fire extinguisher and press down the handle. Using a sweeping motion, spray the entire area of the fire, sending the spray to the bottom of the flames.
5

Continue the instructions in Step 4 until you extinguish the fire. Slowly move away from the area, continuing to check for embers trying to re-ignite.
