If you have an electrical emergency, such as a fire or shock, the first thing you should do is call 911. Once you are safe, you should contact an electrician to repair the problem.

A GFCI outlet, or ground fault circuit interrupter, is a type of outlet that provides protection against electrical shock. GFCI outlets are required in wet areas, such as bathrooms and kitchens, because they can help to prevent electrocution if a person comes into contact with water while using an electrical appliance.Standard outlets do not provide the same level of protection as GFCI outlets. If you are using an electrical appliance in a wet area, it is important to use a GFCI outlet to protect yourself from electrical shock.

Test smoke alarms every month by pressing their test buttons. If your alarms use regular batteries, swap in fresh batteries at least once a year. A “chirping” sound means that it's time to change batteries. Because alarm sensors wear out, replace each alarm at least every 10 years.
