Natural Gas Detection
Know the Smell of Natural Gas
Natural gas is naturally odorless and colorless. To make natural gas detectable, a chemical known as Mercaptan is added. Mercaptan has a smell similar to rotten eggs. If your nose detects this unique odor, contact UGI immediately at 800-276-2722.
Remember, there is no charge for UGI personnel to come and investigate a natural gas odor.
In addition to the odor mentioned above, indications of a gas pipeline leak also include:
- A hissing sound
- Blowing dirt, grass or leaves near a pipeline
- Water bubbling or blowing into the air at a pond, creek or river
- A patch of dead grass or vegetation in an otherwise green area
- Flames coming out of the ground or burning above the ground
