Q: What Is a gas shut-off valve for earthquakes?

Q: Besides grounding outlets, how else can I protect my home?

• <div><p>Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.</p></div>
