In homes or businesses where gas fuel sources are used, gas leaks pose a dangerous risk to your health and safety. Odorants are often added to the gasses to make leaks easier to detect. If you begin to smell a foul smell like rotten eggs, there could be an issue with one of your home or business's gas appliances, such as your furnace. This may mean components have malfunctioned, or there is an issue with the appliance's fuel supply lines. Gas leaks can also occur in the utility company's supply lines which run to your home from the main supply lines. In either scenario, quick and accurate detection is essential.
