Natural gas is completely safe when it's sealed inside pipes and used correctly. Danger occurs when natural gas leaks out or doesn't combust properly in appliances.
Use your senses to detect a gas leak:
- Sight: dead vegetation or bubbling water near a gas meter or dirt blowing near a pipeline
- Smell: rotten egg or skunk
- Sound: hissing
If you suspect a gas leak, leave the area and call 911.
