A propane system is one of the safest ways to heat a home, and it stays that way when the tank, lines and appliances get a little attention before cold weather sets in. Winter is when propane works hardest, and it is also when small problems like a snow-covered regulator or a tank that runs dry turn into service calls. This propane tank safety checklist covers what every homeowner should know, from recognizing a leak to keeping the tank clear and full all season.
How a home propane tank is built to stay safe
Residential propane tanks are heavy steel pressure vessels built and installed to national codes. A few features do most of the safety work:
- Pressure relief valve. If pressure inside the tank climbs too high, for example on a very hot day, this valve releases a small amount of vapor to bring it back down.
- Regulator. The regulator reduces tank pressure to the low, steady pressure your appliances are designed for.
- Service valve. The main shutoff valve under the tank dome lets you stop the flow of gas to the house in an emergency. Turn it clockwise to close it.
- Room to expand. Tanks are filled to roughly 80 percent of capacity, never to the top, so the liquid propane has room to expand as temperatures change. A gauge reading near 80 after a delivery is normal.
Propane itself is colorless and nearly odorless. Producers add a strong odorant so a leak can be detected by smell, which is why the rotten egg or skunk-like odor matters so much.
What to do if you smell propane
If you notice that rotten egg smell inside or around your home, act right away. The Propane Education & Research Council recommends these steps:
- No flames or sparks. Put out cigarettes and open flames. Do not flip light switches, use appliances or use phones, including cell phones, in the area.
- Leave the area immediately. Get everyone, including pets, out of the house.
- Shut off the gas at the main service valve on the tank if it is safe to do so.
- Call from a safe distance. Contact your propane supplier from a neighbor’s house or another location away from the leak. If you cannot reach your supplier, call 911 or the local fire department.
- Stay out until your propane supplier, an emergency responder or a qualified technician says it is safe to return.
- Have the system checked by a qualified technician before using any propane appliance again.
Some people have a reduced sense of smell, and odorant can occasionally fade in new piping or in some soil conditions. A UL-listed propane gas detector, installed according to the manufacturer’s instructions, adds a second layer of protection. Carbon monoxide alarms on every level of the home are also a must for any fuel-burning appliance.
Your winter propane tank safety checklist
1. Keep the tank and regulator clear of snow and ice
After a storm, gently clear snow from the tank dome, regulator and vent so moisture cannot freeze inside the regulator. Use a broom rather than a shovel or ice pick, which can damage fittings. Mark the tank location with a tall flag or stake so snowplows and your delivery driver can find it.
2. Keep a clear path for delivery
Your driver needs a safe route from the truck to the tank. Shovel or plow a path, trim back overhanging branches, and keep vehicles, firewood and equipment away from the tank and the delivery hose route.
3. Clear appliance and chimney vents
Drifting snow can block the outside vents for furnaces, boilers and water heaters. A blocked vent can push carbon monoxide back into the house, so check vents after every heavy snowfall.
4. Never store or use outdoor cylinders indoors
Grill cylinders and portable heater tanks belong outside, upright and away from doors and windows. Never use an outdoor grill or patio heater inside a home, garage or tent.
5. Do not run out of propane
Running out is more than an inconvenience. When a tank empties, pilot lights go out and air and moisture can enter the system. If a valve or gas line is left open, gas can escape when service is restored. That is why a qualified technician needs to check the system for leaks and relight pilots after a runout, and in many areas this check is required by code. The simplest way to avoid it is to watch the gauge and schedule delivery when it reaches about 25 to 30 percent, or let your supplier handle it for you.
6. Schedule a professional safety inspection
If you have moved into a home with an existing propane system, added a new appliance, or cannot remember the last inspection, it is time for one. A technician will check the tank, regulator, lines and connections and test for leaks.
7. Leave repairs to professionals
Do not attempt to repair, move or paint over the regulator or valves yourself. Only qualified propane service technicians should work on tanks, regulators and gas lines.

Frequently asked questions
Is it safe to have a propane tank near my house?
Yes, when it is installed by a qualified supplier. Required distances from buildings, windows and property lines depend on tank size and local codes, and your supplier will place the tank to meet them.
What does propane smell like?
Propane has an added odor that most people describe as rotten eggs, a skunk spray or a dead animal. If you notice it, follow the steps above right away.
What happens if I run out of propane?
Your appliances shut down and pilot lights go out. A qualified technician will need to perform a leak check before the system is put back into service, so it is best to keep the tank above 20 percent through the winter.
How often should a propane system be inspected?
Have it inspected when you switch suppliers, add or replace an appliance, after a runout, or any time you suspect a problem. Your supplier can recommend a schedule for your system.
