What safety feature should be used on extension cords in damp conditions?

GFCI protection is an essential safety feature for extension cords used in damp conditions. Ground Fault Circuit Interrupters (GFCIs) are designed to protect individuals from electric shock by quickly disconnecting electricity in case of a fault. In wet environments, the risk of electric shock increases significantly, as water can create unexpected paths for electricity. By using extension cords with built-in GFCI protection, users are safeguarded against potential electrical hazards, making it crucial for any electrical task involving moisture or dampness. This feature helps ensure that any inadvertent moisture does not result in serious injuries, promoting a safer work environment.
