Gas leaks can be disastrous, and since the gas is invisible, most people don’t realize they are there. Gas leaks are dangerous because they can cause a fire or explosion resulting in fire and property damage, personal injury, and even death. If you suspect you have a gas leak, leave the area immediately and call a professional.

The Environmental Protection Agency estimates that 2.5 billion gallons of gasoline are leaked into our environment every year. That’s enough to fill 200 million cars with gas, and the resulting pollution could harm more than 5,000 people living near a leak. Gas leaks can put you, your family, and your pets at risk of cancer, lung disease, and other health problems. To reduce the risk, use gas detectors to check for leaks in your home and workplace, and regularly check your appliances and your vehicle’s gas tank.
