When a carbon monoxide alarm goes off, you should always take it seriously. Infrequent and occasional chirps often point to a low battery, a faulty device, or dust buildup (this usually affects smoke detectors and not standalone CO detectors). A continuous alarm signals an emergency, and you should immediately evacuate and call 911. When it comes to carbon monoxide in your home, it’s better safe than sorry.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

Recessed lights, as with any kind of light, can be a fire hazard if not installed correctly. Because of this, it’s best to have a professional complete the installation for you. Properly installed lights should not pose a threat and often have heat sensors installed in them that turn the light off if the temperature gets too high.

Yes, a hot or overheating outlet is a fire hazard and can cause a fire. An outlet becoming hot indicates an electrical problem, such as an overloaded circuit, loose connections, or a faulty component. The heat from these issues can ignite nearby flammable materials like curtains or furniture. If you notice an outlet is hot to the touch, turn off the power at the circuit breaker, unplug any connected devices, and consult a qualified electrician. If a fire does start, use a Class C fire extinguisher or baking soda to suppress it, or evacuate immediately and call the fire department.
