Smelling gas in your home or business is something you should never ignore. Propane is a safe and efficient energy source when handled correctly, but even the smallest leak can quickly turn dangerous. 

Knowing exactly what steps to take in the event of a suspected leak can protect your property, your loved ones, and yourself. This guide walks you through the actions you should follow if you ever smell gas.

Recognize the Warning Signs

Propane has a strong, unpleasant odor that’s often compared to rotten eggs or a skunk’s spray. This smell is deliberately added to help you detect leaks quickly. If you notice this odor inside your home, garage, or near a propane tank, treat it as a serious emergency.

Step 1: Leave the Area Immediately

Your first priority should always be safety. Get everyone out of the building or away from the leak source right away. Avoid lingering to investigate, and don’t try to find the exact location of the leak yourself.

Step 2: Avoid Flames and Sparks

Do not light matches, use lighters, or switch on electrical appliances. Even something as small as flipping a light switch can ignite propane vapors. Leave everything as it is until the area is deemed safe by professionals.

Step 3: Shut Off the Gas Supply (If Safe to Do So)

If your propane system has a shut-off valve and it’s located outdoors in a safe area, you may turn it off. However, only do this if you can reach it quickly without putting yourself in danger.

Step 4: Call for Help

Once you’re at a safe distance, contact your propane supplier or emergency services right away. Explain the situation clearly so they can respond quickly and appropriately.

Step 5: Wait for Professionals

Never re-enter the property until a qualified propane technician or emergency responder tells you it’s safe. They will test for leaks, repair any issues, and ensure the system is secure before you return.

Preventing Future Propane Leaks

Routine maintenance is the best way to reduce the risk of propane leaks. Schedule regular inspections for your tank, appliances, and gas lines. Make sure everyone in your household understands propane safety basics and knows what to do in case of an emergency.
