# Propane Safety Basics Every NM Household Should Know

If you heat your home or run a small business with propane across Pecos, Mountainair, Moriarty, or anywhere in our 35-mile service radius, you're relying on a fuel that's safe when handled right—and dangerous when it isn't. At Southwest Propane, we've delivered to thousands of households in central New Mexico, and we've learned that most safety issues stem not from equipment failure, but from not knowing what to watch for. This post covers what propane actually smells like, what to do if you detect a leak, how to use a detector properly, and when to call us versus when to evacuate.

What Propane Smells Like (And Why It Matters)

Propane is naturally odorless. The strong, rotten-egg or skunk-like smell you've heard about? That's an additive called mercaptan, injected at the refinery so you can detect a leak. If you smell that distinctive odor near your tank, appliances, or lines, take it seriously.

In our high-desert climate, with temperature swings from below freezing to 90+ degrees, propane systems expand and contract seasonally. Connections can loosen. Regulators can wear. The smell is your early warning system. Don't ignore it, and don't assume it's something else.

What to Do If You Smell Gas

If you detect propane odor inside your home or near your tank:

Do not turn on lights, strike a match, or use your phone indoors. Static electricity or a spark could ignite the gas. Instead, leave the building immediately and move to a safe distance—at least 50 feet away.

Once you're outside and safe, call 911 first, then call us at (505) 407-2260. Tell the dispatcher you smell propane. Do not re-enter the building until emergency responders and our team have cleared it. If the smell is faint and only near your outdoor tank (not inside), you can call us directly, but err on the side of caution.

For small commercial accounts—restaurants, shops, or farm operations—the same rule applies. A leak near a propane grill or heater is not a "wait and see" situation.

Leak Detectors: How to Use Them Right

A propane leak detector (handheld or fixed-mount) is a smart investment, especially if you have older appliances or live far from town. But a detector is only useful if you maintain it and know how to read it.

Battery-powered handheld detectors should be tested monthly. Most have a test button; press it to confirm the sensor is responding. Replace batteries annually, even if the detector still works—a weak battery can miss a real leak. Keep the sensor clean and free of dust.

Fixed-mount detectors (wall or ceiling units) should be checked quarterly. Listen for a beep or indicator light during the test cycle. If your detector doesn't respond, replace it. Detectors have a lifespan—typically 5–7 years—so if yours is older, replace it.

Detectors are not a substitute for your nose. The mercaptan additive is designed to be smelled at very low concentrations. If you smell propane, trust your nose first and use the detector as confirmation.

When to Call Southwest Propane vs. When to Evacuate

The line between "call for service" and "evacuate now" is simple: If you smell propane inside your home, evacuate and call 911. Do not wait for us to arrive. If the smell is faint and only near the outdoor tank on a cold day, call us directly—it may be condensation or a minor regulator issue.

Here are common scenarios:

Faint smell near the tank on a freezing morning: Call us. Likely condensation or a loose connection.
Strong smell inside the house: Evacuate. Call 911. Then call us.
Smell near a propane grill or heater: Evacuate the area. Call 911 if indoors. Call us if it's an outdoor appliance and the smell clears quickly.
Hissing sound at the tank or regulator: Evacuate the area and call us immediately.

Our team is trained to locate and repair leaks safely. We follow NFPA 58, the national standard for propane system safety, which covers everything from tank installation to appliance connections. We're here to help—don't hesitate to call with questions.

A Quick Safety Checklist

Know what propane smells like (rotten egg or skunk).
Test your leak detector monthly; replace batteries annually.
Never ignore the smell—evacuate and call 911 if it's strong or indoors.
Keep your outdoor tank area clear of snow, ice, and debris.
Have your appliances and lines inspected annually.
Know where your main shut-off valve is and how to close it (ask us to show you).
