On rare occasions, propane can lose its odor. There are several causes of odor loss, including:
- Air, water or rust in a propane tank or cylinder.
- Propane is leaking underground and passing through the soil.
- Propane odor is sticking to the inside surfaces of gas piping, distribution systems and possibly other materials.
Since there is a possibility of odor loss or a problem with your sense of smell, you should respond immediately to even a faint odor of gas. If you’re concerned that you or others in your home may have difficulty smelling propane, consider buying one or more propane gas detectors.
