What You'll Learn
Power outages
Identify the Scope of the Outage
Determine if the power outage is limited to your home or affects your entire neighbourhood. Outages that affect the entire neighbourhood are usually fixed by the electrical company. If the outage is isolated to your home, contact your electricity supplier or a licensed electrician to investigate and resolve the issue.
Shut Off the Power
To prevent damage from electrical surges when the power returns, shut off the power at the main breaker. Turn off all appliances, outlets, and lights. Leave one light on as an indicator of power restoration.
Take Measures for Comfort and Safety
Use flashlights, candles, blankets, and battery-powered fans to stay comfortable during the outage. Keep refrigerators and freezers closed to maintain their temperature for as long as possible. Avoid using a gas stove or oven to heat your home, as this increases the risk of carbon monoxide poisoning and fires.
Prepare for Extended Outages
Extended power outages can impact your food supply and water safety. Have enough non-perishable food and water to last through the outage. Use coolers with ice to keep food cold if necessary. Monitor refrigerator and freezer temperatures with a thermometer, and throw out food if the temperature rises above 40 degrees Fahrenheit.
Alternative Power Sources
Consider using a generator or battery power sources like portable chargers or power banks to meet your essential needs during the outage. However, always use generators outdoors and away from windows to prevent carbon monoxide poisoning.
By following these steps, you can effectively manage a power outage, ensuring your safety and minimising disruptions until power is restored.

Electrical fires
To prevent electrical fires, it is essential to be vigilant and identify potential hazards. Regularly inspect your electrical systems for any signs of wear and tear or overheating components. Ensure that your circuits are not overloaded, and avoid using extension cords with major appliances as they can overheat and start a fire. Keep flammable objects away from heat sources, such as light bulbs and lamps.
If you detect a burning smell, it could indicate an electrical issue. A persistent burning odour, distinct from cooking or heating appliances, may signify overheating wires or electrical components. In such cases, turn off the power supply immediately and seek professional electrical assistance to prevent potential hazards.
In the event of an electrical fire, your top priority is to ensure the safety of yourself and others. If it is safe to do so, disconnect the power source by cutting the electricity at the main breaker. Do not use water to extinguish electrical fires, as it may lead to electrocution. Instead, use a fire extinguisher specifically designed for electrical fires, such as Class C in the US, Electrical in the UK, or Class E in the EU. If the fire is spreading, evacuate the premises immediately and call emergency services.
After the fire has been extinguished, contact a licensed electrician to inspect the damage and perform any necessary electrical repairs. Electrical fires can cause significant harm to electrical systems and devices, so it is crucial to have a professional assess the situation and ensure your safety.

Electric shocks
If you experience an electric shock from a socket or a piece of equipment, isolate the power source at the fuse board and contact an electrician or electrical company to inspect and repair the electrical system. This will help to prevent future incidents. A circuit breaker is designed to trip when there is an overload or a short circuit, protecting the electrical system from damage and preventing fires. However, if your circuit breaker is frequently tripping without any apparent reason, it could indicate an underlying electrical issue that requires immediate attention from a professional electrician.
In the United States, about 1,000 people die each year from electrocution, with many more experiencing non-fatal electric shock injuries. While electrical injuries do occur at the standard voltage of 120 volts, they are usually not fatal. However, fatalities have occurred from electrical sources as low as 42 volts. The most common delayed electric shock symptoms are infection and cardiac arrest. Prompt medical care can reduce the risk of these delayed complications.

Circuit breaker failures
Circuit breakers are essential in homes as they protect circuits from overloading and prevent electrical emergencies. However, circuit breakers can sometimes fail due to heat, excessive use, or voltage surges and spikes. When a circuit breaker fails, your home becomes more susceptible to power outages and electric shocks, which can lead to electrical fires. Therefore, it is important to be vigilant and take immediate action to prevent potential hazards.
Signs of a Faulty Circuit Breaker
There are several signs that may indicate a faulty circuit breaker. If you notice any of the following, it is important to call a professional electrician for an inspection to prevent any potential electrical emergencies:
- Frequent tripping of the circuit breaker without any apparent reason
- Burning smell near the circuit breaker or electrical panel box
- Heat or evident damage to the circuit breaker or electrical panel box
- Inability to reset the circuit breaker properly
Preventing Circuit Breaker Failures
While circuit breaker failures can occur due to various reasons, there are ways to minimize the chances of failure:
- Use a surge suppressor with electrical panels to protect against voltage surges and spikes.
- Ensure that wires are tightly connected to the breaker and check for similar connection errors on all connected appliances.
- Regularly inspect and maintain wiring in conduit systems to prevent problems such as short circuits, blown fuses, or fire accidents.
Responding to a Faulty Circuit Breaker
If you suspect a faulty circuit breaker, it is important to take the following steps to ensure your safety and prevent further issues:
- Turn off the power supply to your house to prevent any potential electrical fires or shocks.
- Call a professional electrician to inspect and repair the circuit breaker.
- If there is a burning smell or signs of fire, treat it as an electrical emergency and follow the appropriate steps, such as evacuating the house and calling emergency services if necessary.

Downed power lines
Electrical emergencies can put people or property at risk, and one of the most apparent electrical emergencies is a power outage. A downed power line is an electrical emergency that requires immediate attention and can be extremely dangerous. Here are some important safety measures and guidelines to follow in the event of a downed power line:
Keep Your Distance
If you encounter a downed power line, it is crucial to stay away from the affected area. Warn others to stay clear of the area as well. Assume that any downed or low-hanging power line is energised and dangerous, even if it does not show any visible signs, such as sparking or smoking. The electrical current in these lines can be strong, and coming into contact with them can result in serious injury or even death.
Vehicle Safety
If a downed power line comes into contact with your vehicle, it creates a hazardous situation for those inside and nearby. If it is safe to do so, move your vehicle away from the power line. If the vehicle cannot be moved, it is important to stay inside until utility workers advise it is safe to exit. If you must exit the vehicle due to a fire or other imminent danger, do not touch the vehicle and the ground simultaneously. Jump clear, ensuring your feet touch the ground at the same time, and shuffle away, keeping your feet close together.
Report the Emergency
Call 911 or your local emergency services immediately to report a downed power line. Provide the exact location, including whether it is on private property, and any potential risks or dangers. Also, contact your electricity supplier or electrical company to report the issue.
Home Safety
If a downed power line affects your home, shut off the power at the main breaker to prevent a sudden surge when the power resumes. Turn off all appliances, outlets, and lights. Additionally, keep children and pets away from the area, and watch out for signs of fire.
Remember, electrical emergencies can pose significant risks, so it is important to act quickly and follow safety protocols to minimise potential hazards and protect yourself and others.
