To stop a space heater fire, don’t place them near or on flammable items, don’t leave them unattended, and don’t use extension cords with them. If a small electrical fire starts and you can safely disconnect the power, do so and then use baking soda on the fire to put it out. Do not use water around electrical outlets. You can also turn off the breaker if reaching the plug is not an option. If the fire is large, get out and call 911.
