Proper extension cord safety means more than plugging items into an extension cord and hoping for the best. You should never plug a power strip into a power strip, also known as daisy-chaining. Additionally, practice other tenets of extension cord safety, such as regularly inspecting your cords and not overloading them with too much wattage.
Have you ever thought it was a good idea to plug a power strip into another power strip? The concept seems simple, especially if you need extra cord length and do not have an extension cable on hand. However, if you understand how electric currents work, you will know that this is actually inviting disaster.
What Are Some Key Tips for Extension Cord Safety?
How can you practice extension cord safety without sacrificing function or productivity? Here are some useful tips to keep in mind.
Never Leave Extension Cords Exposed to the Elements
While it may seem tempting to leave a cord outdoors rather than dragging it inside, you never know what the weather might bring. Surprise storms or other weather events can damage the extension cord, and if it is plugged in, it can lead to disaster.
If you absolutely must have extension cords outdoors, protect them with covers specially designed to withstand the elements.
Always Conform to OSHA Requirements
The Occupational Safety and Health Administration (OSHA) has requirements regarding extension cord use in the workplace. Durability, for example, must be rated for hard or extra-hard use to comply with OSHA guidelines.
OSHA also recommends using watertight connectors to avoid excess moisture leaking into cords and causing further damage.
Look for Damage Before Every Use
Even if you have just used an extension cord, always do a spot check for damage before plugging it in. Even a simple glance could mean the difference between spending a few extra dollars on a new cord and dealing with millions in damage because of an electrical fire.
Perform a Regular Equipment Inspection
Professionally inspect your equipment, including extension cords, regularly. This does not just apply to US-based companies.
You can use test and tag services in Auckland, for instance, to ensure that your New Zealand business is properly set up to avoid electrical hazards.
Do Not Leave the Cord Plugged in for Long Periods
Generally, extension cords are for temporary use. Keeping them plugged in for extended periods will speed up wear and tear, which could end up costing you more overall and also leave your business more at risk for fires.
Additionally, extension cords have thinner wiring than permanent electrical systems. They are prone to overload and overheating if left plugged in for too long.
All it takes to avoid this is unplugging immediately when you finish using the cord.
Watch for Workplace Electrical Hazards
Electrical hazards can exist outside of the function of the extension cord itself. Do not leave extension cords across walkways or in areas with high foot traffic, as these actions can lead to workplace injuries.
Similar to the guidance regarding power strips, do not plug one extension cord into another extension cord.
Which Is Safer, a Power Strip or an Extension Cord?
A power strip is usually safer than an extension cord, although that safety depends on how you use it. Extension cords tend to be safer if you need extra electrical cable, rather than daisy-chaining one power strip into another.
However, for normal purposes, power strips are safer when used correctly. They offer key advantages such as surge protection and can be used for much longer periods than extension cords.
Can You Plug a Power Strip Into a Power Strip?
Physically, yes, but it is not a good idea. When you plug the second power strip into the first, it draws even more power from the first, rather than from the wall socket.
Increased load can easily overload one or both of the power strips.
Additionally, daisy-chaining often leads to overheating, which will then cause equipment malfunctions. When these parts are not functioning properly, you are at higher risk for electrical fires.
Frequently Asked Questions
What Are the Safest Extension Cords to Use?
Ultimately, the safest extension cord to use depends on your specific needs. Extension cords that will primarily be used outdoors, for instance, need to be thicker and have more weatherproof properties to avoid electrical fires or other hazards.
They should also be able to power high-voltage outdoor tools like weed whackers.
Indoor plugs have a different set of quality requirements. Surge protection is important for indoor power strips, for example, especially those that power entertainment or home office systems.
What Are the Chances of an Extension Cord Catching Fire?
Extension cord fires are only as risky as you make them. If you follow proper usage guidelines, you can greatly reduce the chances of an electrical fire caused by an extension cord.
The main issue is that many consumers do not understand power limitations. Electrical Safety Foundation International reports that thousands of home fires occur every year as a result of extension cord misuse.
Imagine scaling the damage caused to a home up to a commercial workspace or warehouse, and you will quickly understand why safety compliance is not optional.
Is It Safe to Have Two Extension Cords Plugged Into One Outlet?
If the plugs have separate sockets, then it should be fine. When each extension cord is directly plugged into a different wall socket, the socket can distribute the power evenly, which is much safer than daisy-chaining extension cords.
What Should You Never Plug Into a Power Strip?
While power strips are incredibly versatile, they still have limitations. You should avoid plugging in high-voltage items and those that have motors, as these will likely overload the power strip and can cause an electrical accident.
