Gas fires are destructive and deadly! It is crucial to have a proactive approach to prevent such from happening and limiting its repercussions. Among others, one thing that can help is to have the best natural gas detectors.

Natural gas vapors are lighter compared to air. They will rise and dissipate. In high concentrations, they can be a potential fire hazard, especially when they are near ignition sources. It can also cause respiratory health problems.

To prevent natural gas from bringing dangers, detection is the key. You cannot rely on your nose since the natural gas leak is odorless. Although, some companies add smell to the gas to make it easy to detect. Despite this, using a gas leak detector is a better alternative.

Are you looking for the best natural gas detector in the market? Keep on reading and learn from the valuable insights we’ll share in this short buying guide.

What is Natural Gas?

Natural gas is a fossil energy source that forms deep on the surface of the earth, making them naturally present in the atmosphere. This mixture of gases is rich in hydrocarbons.

It is used for the generation of fuel and electricity. However, it should be noted that they are not used in their purest form. Instead, they go through processing to make them cleaner.

Whether it is at home or businesses, natural gas has plenty of uses. The most popular is the generation of electric power. Gas turbines are used in power plants.

In the United States, more than half of the homes are supplied with natural gas through tanks ad pipelines. They are used for space heating and water heating.

For industrial applications, on the other hand, natural gas can be a raw material or a source of heating.

Mercaptan is often added to natural gas. This is the one responsible for giving the gas a smell similar to a rotten egg. This makes its detection a lot easier.

The Dangers of Natural Gas

The need for a high-quality detector arises from the fact that natural gas is dangerous. It may be invisible, but it has huge hazards, making it important to detect its presence.

Natural gas is dangerous when it enters the body through inhalation. Breathing gas emissions can cause health problems. These will become worse the longer the exposure is.

Exposure to high levels of natural gas can cause nausea, loss of consciousness, fatigue, severe headache, and death by suffocation. Despite the health dangers, take note that natural gas is non-toxic. This is also its main difference from carbon monoxide.

When natural gas leaks, it can also be a risk of explosion. An odorant is often added by the providers of natural gas to prevent such a problem.

More so, natural gas leaks can be bad for the environment. It is a powerful greenhouse gas that can contribute to global warming and climate change, especially methane.
