Keep dangerous appliances and power cords away from children
It is important to keep dangerous appliances and power cords away from children. Children are naturally curious and like to imitate their parents, so it is crucial to take extra precautions to ensure their safety. Here are some ways to keep dangerous appliances and power cords out of children's reach:
Keep Appliances Out of Reach
Store dangerous appliances, such as toasters, blenders, and electric kettles, on high shelves or in locked cabinets where children cannot access them. This simple step ensures that children cannot accidentally turn them on or come into direct contact with them.
Educate Your Children
Teaching children about electricity and electrical safety is crucial. Educate them on the dangers of electricity and how to safely use electrical devices. Explain that electrical outlets, sockets, and plugs are not to be played with and that they should never stick any objects into them. As they get older, teach them the correct way to plug in and unplug appliances, always by the plug and not the cord.
Use Safety Devices
Invest in safety devices such as socket covers, power strip covers, and ground-fault circuit interrupter (GFCI) outlets. Socket covers are made of durable plastic and prevent children from inserting their fingers or objects into electrical outlets. Power strip covers protect against the temptation of exposed plugs, which can be a serious hazard. GFCI outlets reduce the risk of electrical shock by monitoring the power flow to the appliance.
Regularly Check and Store Cords
Regularly inspect power cords for any signs of damage, such as fraying or cracking, and repair or replace them as needed. When storing cords, keep them away from children and pets, and avoid wrapping them tightly around objects, as this can cause stretching or overheating.
Set Rules and Boundaries
Establish clear rules about which appliances children are allowed to operate and when. For example, you might decide that only adults are allowed to turn on certain lamps or electronic devices. Additionally, set boundaries around high-risk areas, such as substations, utility towers, and pad-mounted transformers (green metal boxes). Teach children to recognize "Danger: High Voltage" signs and to stay away from these areas.

Check for damaged electrical cables and loose wires
Electrical safety is no small matter. In the United States alone, there are 31,000 home electrical fires and 180 cases of electrocution or electricity-related incidents each year. Faulty or damaged wiring and related electrical equipment are the leading causes of electrical fires, so it's important to regularly check for damaged electrical cables and loose wires.
Checking for Damaged Electrical Cables
Damaged power cords are a serious safety risk and can cause both fires and electrocution. All power and extension cords should be regularly inspected for signs of fraying and cracking, and repaired or replaced as necessary. Power cords should not be stapled, wrapped tightly around objects, or placed under rugs and furniture, as this can cause them to overheat, or the insulation to be damaged. Cables should also be kept away from water, as this combination can be deadly.
Checking for Loose Wires
Loose wires can occur due to wear and tear, dry rot, rodent damage, or loose connection points. If you suspect a wire may be loose, you can use a voltage detector, multimeter, clamp meter, or broken wire detector to locate the issue. Alternatively, you can test the resistance between the hot wire and the ground from the outlet or breaker when off, though this requires a megohmeter. If you find a loose wire, you can attempt to repair it yourself, or contact a professional for help.
Repairing Loose or Damaged Cables
First, identify the type of cable and the extent of the damage. Some cables are designed to be easily replaced, while others may require more skill and care to repair. Gather the right tools and materials, which may include a wire stripper, a sharp knife, a soldering iron, solder, heat shrink tubing, or electrical tape. After joining the wires and restoring the electrical connection, cover the exposed wires to protect them from external factors. Finally, reconnect the cable and test its functionality.

Avoid overloading sockets and plugs
Overloading sockets and plugs is a common cause of electrical fires. It is important to avoid plugging too many devices into too few sockets, especially when using extension leads and USB ports. Even if there is space to plug in multiple appliances, it does not mean it is always safe to do so. Some appliances require a lot of power, and when grouped together, they can cause the plug to overheat and possibly start a fire. High-powered appliances, such as kettles, washing machines, or dishwashers, can easily overload an adaptor or extension lead.
To avoid overloading sockets, follow these tips:
- Check the current rating of the extension lead before plugging in appliances. Most are rated at 13 A, but some older versions may be rated at only 10 A or less. The rating should be clearly marked on the extension lead, and if not, refer to the manufacturer’s instructions.
- Never overload an extension lead by plugging in appliances that together exceed the maximum current rating stated for the extension lead. This could cause the plug in the wall socket to overheat and possibly cause a fire.
- Use a multi-way bar extension lead instead of a block adaptor, as this will put less strain on the wall socket. Some block adaptors do not have a fuse, which increases the risk of overloading and fire.
- Avoid "daisy-chaining" extension leads together. Using more than one extension lead per socket significantly raises the risk of overloading the socket.
- Consider having additional sockets installed if you regularly rely on extension leads and adaptors. Ensure that a qualified electrician carries out the installation work.
In addition to these specific measures to avoid overloading sockets and plugs, there are other general electrical safety practices to follow. Keep dangerous appliances, such as toasters, blenders, and electric kettles, out of the reach of children. Regularly check power and extension cords for signs of fraying and cracking, and repair or replace them as needed. Unplug appliances when they are not in use to protect them from overheating or power surges and reduce phantom drain.

Keep electrical devices away from water
Water and electricity is a deadly combination, and it is important to keep electrical devices away from water sources. Here are some ways to do this:
Firstly, it is crucial to keep electrical appliances away from water sources and never operate them with wet hands or while standing on a wet surface. This includes not using any electrical appliances near a bathtub, sink, or swimming pool. It is also important to teach children not to splash water out of the bath, as this can reach electrical outlets.
Secondly, it is recommended to install Ground Fault Circuit Interrupters (GFCIs) in areas where water and electricity are likely to come into contact, such as kitchens, bathrooms, and outdoor outlets. GFCIs are electrical safety devices that quickly shut off power in the event of a ground fault, and they are required by the National Electrical Code (NEC) in certain areas.
Thirdly, it is important to keep electrical cords and wiring away from hot surfaces and water sources. Cords should not be wrapped tightly around objects or placed under rugs or furniture, as this can cause damage or overheating. When storing cords, keep them away from children and pets to prevent chewing or playing.
Additionally, always unplug appliances when they are not in use, and do not use wet appliances. Moisture can damage the motor and cause electrical shocks when plugged in. If an appliance falls into the water, do not reach for it while it is still plugged in. Instead, switch off the power at the mains and unplug the appliance before touching it.
Finally, always use weather-resistant outdoor outlets, and ensure that any weather cover over an outlet is intact and not leaking.

Unplug devices and appliances when not in use
Unplugging devices and appliances when they're not in use is an effective way to protect your home from electrical fires and power surges. While it may not make a huge difference to your electricity bill, it can save you money.
According to the United States Consumer Product Safety Commission, 31,000 home electrical fires occur every year, with 69% caused by faulty or damaged wiring and related electrical equipment. Electrical safety is no small matter, and unplugging devices can help to mitigate the risks.
Many appliances and electronics draw small amounts of power even when not in use, and this can add up to noticeable amounts on your monthly bill. The Department of Energy’s Lawrence Berkeley National Laboratory estimates that an appliance that constantly draws one watt of electricity can cost up to $1 per year, and many appliances use more electricity than this.
Unplugging devices can also protect them from power surges. Power surges can be caused by lightning strikes or transformer explosions, and unless you have a whole-home surge protection system, your devices are vulnerable.
Some good habits to get into include unplugging your phone charger when your phone is not charging, and unplugging kitchen appliances like coffee makers when you're not using them.
