A Rotten Egg Smell Can Be Your Best ‘Gas Leak’ Warning

That rotten egg smell could be a warning sign of a gas leak, which is highly flammable and can cause harm to property and human life. Gas companies add mercaptan to natural gas to give it a sulphur-like smell. Prevent a leak by having consistent, annual furnace inspections, making sure your flame is blue, having filters and vents cleaned, and properly ventilating any gas or kerosene heaters. Other signs include hearing a hissing sound or browning of plants. Communicate with your family about the warning signs and add it to your emergency plan. Call your gas company immediately if you suspect a gas leak.
