What to do in case of a gas leak at home?

Unlike other domestic accidents, a gas leak is a phenomenon that should not be taken lightly. If you do not detect it in time, its consequences can be dramatic.

To avoid reaching that point, everyone must know how to react in this situation. If you don’t know much about the subject, this article explains the right actions to take.

But to better clarify our ideas, it is important to first mention the most common causes of a gas leak at home.

Common factors of a gas leak

Before asking yourself how to repair a water leak in a wall, you need to know the origin of the leak. It is the same for a gas leak. It is essential to determine the sources of the problem.

In most cases, the cause is a poorly connected installation. Whatever the appliance used, the stove, boiler, plancha, or the cooktop, it is imperative to ensure that the connecting pipes function properly. Otherwise, gas can escape from a pipe.

This situation is also possible when the installation is old. It should be noted that some equipment has a limited lifespan, for example 10 or 15 years. If this is exceeded, you should expect the system to malfunction.

Similarly, a gas leak can occur due to a poorly maintained appliance. If you have a boiler, know that it requires maintenance every year. Otherwise, a possible leak can be predicted.

The danger of a gas leak

If it is not located in time, the incident causes many consequences. The gas emissions in the air are concerning depending on the concentration percentage.

When the level is below 5%, it often remains without effect. Between 5 and 15%, this situation leads to poisoning threats manifested as nausea, migraine, and fatigue.

From 15%, the risk of fire is not negligible. Above 25%, the lack of oxygen causes asphyxiation. Worse still, the threat of explosion becomes real.

Sign	Risk level	Immediate action	Critical time
Gas smell	High	Ventilate + shut off gas	< 2 min
Headaches	Medium	Leave the premises	< 5 min
Pipe whistling	Very high	Evacuate immediately	< 1 min
Unstable flame	High	Shut off gas supply	< 2 min

What to do in case of a gas leak

Many people tend to panic when they notice a strange smell in the house. However, panic solves nothing.

Discover the simple steps to take to deal with the problem.

Identify the danger

The latter is easily recognizable in case of an unusual spike in your gas consumption. Your expenses remain the same while your bill suddenly rises. This should warn you of a possible leak problem.

In any case, the use of a gas detector is strongly recommended when you use gas-powered equipment. Just like the smoke detector, it does not hesitate to trigger the alarm at the slightest worrying odor.

If you do not have one, you should pay attention to a gas smell in any room of the house. Usually, this is the result of a leak in the installation.

Gas is generally detectable once its concentration in the air is above 1%. To prevent this number from rising, you must act immediately and follow certain instructions.

Avoid creating sparks

The first reflex to apply is to avoid triggering smoke or sparks. To do this, it is strongly advised not to touch electrical devices.

Whether it is your mobile phone, alarm, doorbell, elevator, roller shutters or even switches, avoid using them. They can create flames with which the gas can ignite.

Similarly, you must not light a lighter for any reason or smoke. This risks causing an explosion at some point.

Ventilate the premises

When you notice a suspicious smell in your home, immediately think of opening windows and doors wide.

Thanks to this reflex, you renew the ambient air. Additionally, you can immediately reduce the concentration level of gas in the air. Remember that it can become a real threat when it exceeds 15 %.

However, as we just mentioned above, you should not follow this advice if the openings are electric shutters. Any door lockable by an electric system should not be touched.

Ventilating the room is only applicable for doors and windows without this kind of installation.

Shut off the gas supply

This action is among the most important steps, as it prevents any kind of complication. When you shut off the gas, it normally stops the leak.

To locate the gas supply, consider using a lamp or any other artificial lighting. In most cases, this point is located at the entrance of the dwelling or near the meter.

It is also possible that the leak comes from an appliance. In this case, operate the button or lever that helps you stop the gas supply.

Leave the premises

When evacuating the premises, act calmly. Since the windows are already open, the gas concentration will decrease. In this scenario, there is no need to panic.

It is required to get all residents out. Guide children and elderly people to avoid crowding. If you have pets, they must also go outside.

If you forget objects with sentimental value in the house, do not try to retrieve them. After a specialist’s intervention, you can recover them.

Contact a gas leak detection professional

If you wonder how to change an interior door without changing the frame or how to plane a board, you immediately know you need to call a carpenter. However, in case of a gas leak, it must be admitted that panic rises and prevents clear thinking.

Due to the fire risk, the firefighter is the qualified professional who can intervene and resolve the issue. Once the danger is controlled, think about calling your gas supplier.

A team of technicians comes on site to detect the source of the leak. They provide solutions adapted to the problem to eliminate it definitively.

Inform the neighborhood

A high concentration of gas causes quite serious consequences not only for your home or your health, but also for those around you. It is therefore essential to inform your neighbors of the situation, but in the calmest manner possible.

To do this, avoid touching electrical devices such as the doorbell. Likewise, refrain from contacting them by phone. It is safer to knock directly on their door. You must carefully choose your words to avoid any panic.
