The answer to 'GFCI outlet safety tips' is that GFCI (ground fault circuit interrupter) outlets are an important safety feature that help prevent electric shocks and fires. GFCI outlets monitor the flow of electricity and instantly shut off power if they detect a ground fault, which can happen when electricity flows through a person or something it shouldn't.
To ensure GFCI outlets are working properly, you should test them monthly by pressing the 'test' button, which should cause the 'reset' button to pop out, indicating the GFCI is functioning. You should also replace GFCI outlets every 5-10 years or if they become damaged or worn out. If a GFCI outlet is not working, it's best to call a licensed electrician to diagnose and repair the issue.
