How To Detect A Gas Leak At Home?


One of the safest, convenient, and efficient sources of energy is natural gas. In the United States, people use natural gas to heat water, cook food, and other domestic chores. However, improper installation of natural gas is dangerous for your home. Other poisonous vapor-sources include furnaces and ventilated generators that are not installed correctly.

Carbon monoxide poisoning is a severe problem in the United States. The vapors are highly flammable, and there is a high risk of explosion. Therefore, it is highly essential to detect a gas leak before it becomes dangerous to the occupants. This article is a guide to immediately detecting a gas leak in your home, and how the home security systems help detect a gas leak, thereby preventing catastrophes.

Immediate signs and symptoms of a gas leak

If you do not have a home security system installed, you must be aware of the signs and symptoms of a gas leak. The immediate step you must take if you suspect a gas leak in your home is to turn off the pilot light or gas meter. Next, alert your Gas Company or authorities. The natural gas is odorless, and a smell like rotten eggs is added to make the home occupants warn in case of leakage. A hissing or whistling sound, bubbles or dust in standing water, visible damage to a gas line connection, and sudden dying of the house plants are other signs of a gas leak.

Whenever the level of gas increases, the oxygen level begins to drop. Carbon monoxide poisoning is probable. Its symptoms include breathing difficulties or chest pains, lightheadedness, or dizziness. Other symptoms are headache, eye or throat irritation, nausea or reduced appetite, depression, irritability, or other mood changes, ringing in ears, frequent nosebleeds, and unconsciousness.

Children, older adults, asthma patients, and pets are the first experiencing the symptoms of carbon monoxide poisoning. If proper medical treatment is not provided, prolonged unconsciousness can end up in death. Carbon monoxide detectors are installed in homes for safety purposes. There’s another natural gas, Radon that, unlike carbon monoxide, does not show symptoms easily. So, Radon detector monitoring is advised in the United States.

How can you immediately check for a gas leak?

The rotten-eggs smell will reach your nose, and you’ll be able to check the carbon monoxide gas leak. However, if you are not sure, it is wise to turn off the pilot light on your stove, furnace, or water heater. Also, it would help if you opened the windows and alert authorities immediately. Move out of the house quickly. Listen for a hiss or whistling noise, and stop moving for a minute to focus on what you can hear.

However, it is not necessary that if you notice some noise, there is a gas leak. So, also go for checking the stove or range top. Turning on the burner will give off a blue flame from gas stoves. If orange or red flames appear even after the furnace has been lighted up, there is a gas leak. For immediate safety, add a concentrated solution of a teaspoon of dish detergent to a cup of water, and apply it wherever you suspect a gas leak.

The best way is to install a gas leak detector at home. Many people are using carbon monoxide detectors and smoke detectors to check a gas leak. Home safety includes many features for your comfort and the safety of your home. It also helps detect a gas leak. Here’s a guide on Home security systems.

What are home security systems?

A home security system is a collection of electronic components that aim at working together to protect your home. Home safety devices include security cameras, smoke detectors, carbon monoxide detectors, base station, panic button, yard sign, key fob, glass break sensor, siren, glass break sensor, an entry sensor, and keypad and motion sensor.

Security camera

A Security camera connects with your Wi-Fi so you can live stream footage remotely. It also lets you receive notifications when the camera detects movement, people, and packages. There are unique security cameras with two-way audio, allowing you to speak to whoever the camera is on. Color-night vision feature is also available. Since home safety is essential for all homes and buildings, these cameras have smart platform integrations with Amazon Alexa or Google Assistant to provide comfortable services.

Smoke and Carbon monoxide detectors

Smoke and Carbon monoxide detectors are environmental monitoring systems for your home. They consider not only home safety but also the protection of its occupants. Your home must have a smoke and carbon monoxide detector because it helps you breathe in clean air, thereby avoiding catastrophes. Smoke detectors and carbon monoxide detectors are discussed in the next section.

A base station and Panic Button

Base station aim at syncing all the connected devices with your mobile application. You get notified about all the activities through your phone.

A panic button is useful for home safety equipment when something goes wrong. It is an easy way to alert emergency services(police, hospital, fire department) Although they cannot be installed everywhere, one can keep it close to the bed, in case of an emergency at night.

How does home security work?

A large number of home security systems have components that connect to the base station. They link to a mobile application from the base station, thereby allowing you to monitor and control everything remotely. Most of these home security systems use Bluetooth or Wi-Fi to connect to your phone. Some of the systems even have cellular, landline, or battery backup in case of a power outage. They give you 24/7 home safety.

Arming and disarming of home safety is possible through the mobile application. However, the smoke detectors and carbon monoxide detectors will remain ON even when you disarm the home security system. If your system is armed, the sensors will turn on, and the camera will start recording, and vice versa.

To stream your security camera footage live, you have a mobile application. You can also receive notifications from your sensors, speak through two-way audio (if your camera has the facility), and for several other functions.

How does home safety help detect a gas leak?

Smart home safety devices are different from a local alarm system as it always keeps you updated. The sirens, cameras, smoke detectors, and carbon monoxide detectors in case of a gas leak, alert you, thereby making home safety easier. Here’s how smoke detectors and carbon monoxide detectors help prevent catastrophes in case of a gas leak.

Carbon monoxide detectors

Carbon monoxide detectors are the best devices to prevent Carbon monoxide poisoning. When the gas leaks, they can detect the CO gas. You can install it (along with a smoke detector) in your home. They work like a fire or smoke alarm by emitting a siren when they detect carbon monoxide. This detector has many sensors, including Biomimetic sensors, a metal oxide semiconductor, and an electrochemical sensor. In the Biomimetic sensor, a gel changes color when it absorbs carbon monoxide.

The varied color triggers the alarm. For the Metal oxide semiconductor of carbon monoxide detector, the silica chip’s circuitry detects carbon monoxide. It lowers the electrical resistance, thereby triggering the alarm. In an Electrochemical sensor, the electrodes in a chemical solution sense changes in electrical currents when they come in contact with carbon monoxide, leading to a trigger in the carbon monoxide detector’s alarm.

Smoke detectors

A smoke detector is an important device used to warn occupants of a home of the presence of a fire. A smoke detector alerts us before it becomes too late to escape. On sensing smoke, the sensors emit a loud and high-pitched alarm tone. A flashing light usually accompanies it.

Smoke detectors are useful in case of a gas leak because gases are highly flammable. If this carbon monoxide leak leads to fire, smoke detectors are beneficial. The two types of smoke detectors, Photoelectric and Ionization, are installed as a part of home security systems. Many authorities recommend the use of both smoke detectors in your home.


Home security systems are very beneficial for your home because they keep your home secure and save you from many dangers. Everyone at home must be aware of a gas leak’s signs and symptoms like the rotten-eggs smell, breathlessness, nausea, and others. Small preventive measure like a detergent-mix is useful initially, but you must immediately call the authorities.

Home security systems include smoke detectors and fire detectors to warn you, thereby preventing anything worse from happening. With this home safety and preventive measures, it is always essential to stay alert and get the home appliances serviced regularly. Proper installation of home security systems and the right steps taken at the moment can keep you and your home safe.
