Electrical equipment may be common, but it can also be dangerous. Despite this, electrical devices and equipment can be found in most homes, offices, and workplaces. While most people may not directly work with electricity, following basic safety precautions can keep you and others safe across the board.
Below are some essential tips to remember when working with electrical equipment to avoid injuring yourself or those around you.
Water is not your friend when working with electricity. Always avoid coming into contact with water and using wet hands to touch electrical equipment.
Likewise, avoid using electrical equipment in wet or moist conditions unless it’s specifically designed to be safe near moisture.
Switch off the power to the circuit(s) you’re working with to avoid any electrical hazards. Visit the area's main power source (such as a fuse box or circuit breaker) to shut things down before you get started.
If your equipment has visible signs of damage, such as broken plugs or frayed wires and cords, don’t use it. It’s better to be safe than face the risk of electric shock.
Tools with insulated parts and handles help minimize your chances of being shocked. They are made with materials that won’t conduct electricity and spread it to your body.
It’s also wise to choose an insulated or non-metal ladder, if you’re using one. You can use a ladder with insulated side rails or one made from wood or fiberglass.
Check all electrical equipment and installations on a regular basis for any signs of wear or damage. If you spot signs of a malfunction or damage, repair or replace them as soon as possible.
Personal protective equipment (PPE), like rubber gloves and goggles, will help keep you safe against burns, electric shocks, and other injuries. Always wear PPE when working with electricity in any context.
GFCIs can cut off an electrical supply if a difference between the current flowing into and out of a circuit is detected.
It’s a good idea to install them in areas where water and electricity may come in contact, such as a bathroom or kitchen. Once installed, your GFCIs will need to be checked around once a month to ensure they’re functioning properly.
Minimize the risk of electrical fires and hazards by plugging in only one high-wattage appliance per outlet. The same logic applies to extension cords, too; try to keep the number of things plugged into one area to a minimum.
Always unplug equipment or devices with their head rather than by yanking the cord. Unplug devices slowly and cautiously to lower your risk of electric shock.
Some cleaning materials you might use near electrical equipment can conduct water or are flammable.
Look out for water- and solvent-based cleaners that can conduct electricity. Also, pay attention to which products are marked as highly flammable on their packaging.
Use caution when applying these products; if possible, look for alternatives that don’t pose this risk.
Overall, keeping yourself safe from electrical injuries is relatively straightforward. You can cut many of your risks out by taking safety precautions like the following:
Always take as many precautions as possible before handling electrical equipment. Injuries can happen quickly and become severe, so it’s always better to be safe than sorry.
Some of the most common safety devices used in electrical circuits that help protect users from electric shock include:
Before you plug anything in, ensure your power cords are not damaged or frayed. It’s best to use a cord with a third prong, if possible. Also, confirm your power cords won’t be near water or damp conditions, and avoid plugging in too many in one spot.
When it’s time to unplug, do so gently by gripping the plug’s head, not the cord.
Look out for any signs of damage or burning on outlets and wires. You can also use an outlet tester to verify your outlets are wired properly.
Also, check for loose-fitting plugs or outlets that are hot to the touch. If you have a GFCI, you can press its test button to make sure it works as intended.
Yes, rubber gloves can prevent electric shock, as rubber is not a conductive material. However, it’s best to use gloves designed for electrical work. Other rubber gloves may not be protective enough to prevent electrical hazards.
What is the first step before working inside the case of a working computer?
Always shut down and unplug a computer before opening it up to do work. It also helps to touch a grounded metal object before working to discharge any static electricity that may be on your body.
