When using non-GFCI protected extension cords, it's crucial to follow safety guidelines to prevent electrical hazards. Here are some key measures to ensure safety and regulatory compliance:

• Inspect Before Use: Check extension cords and plugs daily for damage, such as cuts, missing ground prongs, or deformed pins. Remove damaged cords from service immediately.
• Proper Grounding: Use only 3-wire type extension cords and plug them into properly grounded outlets.
• Appropriate Gauge: Use the correct gauge of extension cord for the electrical current it will carry. Refer to an American Wire Gauge (AWG) chart to match wire size with amperage.
• Avoid Misuse: Never use extension cords as a substitute for fixed wiring. Do not run cords through windows, doorways, or holes in walls. Avoid fastening cords with staples or modifying plugs.
• Safe Handling: Do not plug in cords with wet hands or remove cords by pulling on the cord (pull on the plug instead).
• GFCI Protection: Use a portable in-line Ground Fault Circuit Interrupter (GFCI) if the receptacle is not GFCI protected. GFCIs can interrupt the electrical circuit before a current can cause serious injury.
• Proper Use of Extension Cords: Use flexible cords only for their intended purpose. Do not use flexible electric cords connected to equipment for raising or lowering the equipment. Flexible cords must not be fastened or hung in a way that could damage the outer jacket or insulation.
