Computer Hazards: Laptop & Battery Safety
Reason
Lithium-ion batteries in laptops and cordless tools can pose a serious fire risk if they overheat or become damaged. Because these batteries can enter "thermal runaway"—where they catch fire, explode, or release toxic fumes from burning plastics—it is critical to handle them with extreme caution. These procedures provide life-safety steps to manage smoldering devices and ensure proper evacuation during a battery fire.
Emergency Response (Active Fire or Smoke)
- [ ] Call 911 immediately and treat a burning laptop as a real fire emergency.
- [ ] Evacuate all people and pets from the area to avoid fire and toxic fumes.
- [ ] Unplug the laptop from the wall outlet only if it is safe to do so, to stop additional power delivery.
- [ ] Remove the laptop from easily ignited surfaces like couches or beds if it begins to smolder.
- [ ] Clear away nearby papers, pillows, and other combustible materials to prevent the fire from spreading.
- [ ] Move the device outside if the fire is in its early stages to allow fumes to vent safely.
- [ ] Use an ABC dry chemical fire extinguisher or water to douse the device.
- [ ] Maintain a distance of at least 10 feet when using an extinguisher to avoid potential burning shrapnel.
- [ ] Monitor the device for at least 24 hours after the fire is out, as damaged cells can flare back up or re-ignite.
Battery Health and Maintenance
- [ ] Stop using the device immediately if the battery appears swollen.
- [ ] Power down and isolate any device with a faulty battery in a fireproof container.
- [ ] Consult a professional repair technician for battery removal if you have any doubts about doing it safely.
- [ ] Store old batteries outside if you are collecting them for recycling.
- [ ] Use caution with aftermarket or cordless tool batteries, as they have been known to burn or explode.
