And How to Stay Safe This Winter
Did you know that propane leaks may be harder to detect during the colder months? It’s true—and it has to do with how temperature and environment affect the way propane gas behaves.
Propane Is Naturally Odorless
Propane is a colorless and odorless gas. To help detect leaks, manufacturers add a chemical called ethyl mercaptan, which gives propane its signature “rotten egg” smell.
Why the Odor Might Seem to “Fade” in Winter
Several factors can cause the propane smell to be less noticeable in colder weather:
- Cold temperatures slow odor dispersion
In freezing conditions, gas vapor moves more slowly. If there is a small leak, the odorized gas might not disperse quickly enough to be noticed until the concentration is higher—and more dangerous. - Snow or ice may trap the gas
If a leak occurs near or under snow, the gas can collect in pockets instead of dispersing. This slows the spread of the odor, making detection harder. - Heavy winds or moisture may dilute the smell
Wind can quickly carry away vaporized gas, and moisture in the air can interfere with how we perceive smells.
What You Can Do to Stay Safe
Even if you don’t smell propane, trust your other senses and take these proactive safety steps:
- Listen for hissing sounds near the tank, lines, or appliances.
- Look for dead grass, frost, or bubbling water near underground tanks or lines.
- Feel for unusually cold areas on piping—this can indicate a leak.
- Use an electronic gas detector as an added safety measure, especially if you have older tanks or underground lines.
- Pay attention to indoor symptoms such as dizziness, lightheadedness, or difficulty breathing.
🚨 When in Doubt—Call Us!
If you suspect a leak, leave the area immediately and call Delta Liquid Energy or 911 from a safe location. Do not try to turn off the tank or appliance yourself.
