When it comes to electrical safety, cutting corners can lead to disaster. One simple yet critical decision you can make for your business is to use only UL certified extension cords.
According to the U.S. Fire Administration, over 3,300 home fires are caused by extension cords each year. Many of these incidents happen due to non-certified or poor-quality cords. The risk is even higher in business environments, where equipment runs for longer hours and safety regulations are stricter.
UL stands for Underwriters Laboratories, a trusted safety organization that sets standards for electrical products. When an extension cord is UL certified, it means:
It has passed rigorous tests for fire resistance, electrical integrity, and durability.
It meets or exceeds national safety standards like the NEC (National Electrical Code) and OSHA(Occupational Safety and Health Administration) workplace safety rules.
In short, a UL mark is your assurance of safety and reliability.
Here’s why you should choose UL certified extension cords over generic ones:
Prevents Fires and Shocks: Built-in safety features reduce risks like overheating or electric arcs.
Code Compliance: Many workplaces legally require UL-listed equipment under OSHA regulations.
Peace of Mind: Reliable for long-term indoor or office use—especially with expensive devices.
Insurance Protection: In case of accidents, insurers may deny claims if uncertified cords were used.
Using uncertified cords might save money upfront, but the risks far outweigh the cost:
Overheating and Melting: Cheap insulation can't handle high loads, leading to dangerous heat buildup.
Fire Hazards: Poor-quality wiring can spark and ignite flammable materials.
Short Circuits: Faulty construction can cause shocks or power surges.
The Consumer Product Safety Commission (CPSC) warns that many cord-related fires are preventable—if only the right cords were used.
UL certified extension cords aren’t just for industrial spaces. They’re essential in these common areas:
Home Offices: Powering monitors, computers, and printers safely.
Kitchens: For blenders, microwaves, and other small appliances.
Living Rooms: Entertainment systems and lighting setups.
Workspaces: To stay compliant with OSHA and reduce liability risks.
Here’s how to make sure your cords are truly UL certified:
Look for the UL Mark: It should say “UL Listed”, not just “Tested” or “Approved.”
Check the Cord Ratings: Look for AWG (American Wire Gauge), amperage, and voltage limits.
Avoid Fakes: Buy from reputable suppliers. Counterfeit UL labels are common in low-cost imports.
