Warning Signs of a Gas Leak

1. When the smell of gas lasts more than an instant after igniting stovetop burners.
2. When the presence of a foul odor persists.
3. When you cannot find the reason for the foul odor. What you think may be garbage, sewage, or a dead animal may be a serious gas leak.
4. When you hear a hissing noise near a gas appliance, piping, or storage tanks and cylinders.
