What is a Gas Leak?

​

A gas leak occurs when natural gas or another type of gas escapes from a pipeline or other containment. Natural gas is commonly used in homes and businesses for heating, cooking, and other purposes. When gas leaks occur, they can be dangerous due to the risk of fire, explosion, and health hazards.

​

How to Find a Gas Leak

​

Detecting a gas leak early is crucial for safety. Here are some common signs of a gas leak:

1. Smell: Natural gas is odourless, but gas companies add a chemical called mercaptan to give it a distinctive smell, often described as rotten eggs or sulphur.

2. Sound: A hissing or whistling sound near a gas line or appliance can indicate a gas leak.

3. Sight: Look for dead or dying vegetation in an otherwise green area, which can indicate a leak underground. Also, look for dirt or dust blowing from a hole in the ground, or bubbles in wet or flooded areas.

​

What Gas Smells Like

As mentioned, an odorant called mercaptan is added to natural gas to give it a strong, unpleasant smell similar to rotten eggs. This helps people detect gas leaks quickly and take appropriate action. If you smell this odour, it's important to act immediately.

​

The Dangers of a Gas Leak

Gas leaks pose several dangers, including:

1. Fire and Explosion: Gas is highly flammable, and a small spark can ignite it, leading to a fire or explosion.

2. Health Risks: Breathing in natural gas can cause symptoms like headaches, dizziness, nausea, and in extreme cases, can be fatal due to asphyxiation.

3. Environmental Damage: Gas leaks can harm the environment by killing vegetation and contributing to greenhouse gas emissions.

What to Do If You Suspect a Gas Leak

If you suspect a gas leak, follow these steps:

1. Evacuate the Area: Leave the area immediately and move to a safe location away from the suspected leak.

2. Avoid Sparks: Do not use electrical devices, phones, or anything that can create a spark.

3. Call for Help: Once you are at a safe distance, call your gas company or emergency services to report the leak.

4. Do Not Re-enter: Do not go back into the building until it has been declared safe by professionals.
