What Every Propane User Should Know in an Emergency

Propane tanks Old Town, MEPropane is a safe, efficient, and reliable fuel when handled properly. However, if you ever smell gas around your home, business, or propane equipment, it is important to act quickly and safely. Knowing how to shut off your propane tank can help reduce risks while you wait for professional assistance. Understanding the proper steps ahead of time can make a significant difference during an emergency.

Your safety and the safety of your loved ones are important. So let’s review some general propane safety tips.

Recognizing the Smell of Propane

Propane is naturally odorless, but manufacturers add a distinctive odorant that smells similar to rotten eggs or sulfur. This strong smell helps alert people to a potential leak. If you notice this odor, whether inside or outside your property, take it seriously.

Do not assume the smell will go away on its own. Even a small leak can create a hazardous situation if left unaddressed.

What to Do If You Smell Gas

Being prepared can help you respond calmly and effectively if an issue arises. If you think you smell propane, take the following steps:

  1. Leave the area immediately and ensure everyone else does the same. Pets should be removed from the area as well.
  2. Avoid using electrical switches, appliances, telephones, or anything that could create a spark.
  3. Extinguish any open flames, cigarettes, or other ignition sources if it is safe to do so.
  4. Move to a safe location away from the suspected leak.
  5. If it is safe and accessible, shut off the propane supply at the tank.
  6. Contact your propane provider and emergency services.

IMPORTANT: Never attempt to locate the leak yourself or re-enter the building until it has been declared safe by qualified professionals.

How to Shut Off a Propane Tank

Most propane tanks are equipped with a service valve located at the top of the tank. To shut off the propane supply, take the following steps:

  • Locate the main shutoff valve on the tank.
  • Turn the valve clockwise, to the right, until it stops.
  • Do not force the valve beyond its natural stopping point.
  • Once the valve is closed, leave the area and contact your propane supplier for assistance.

If you are unsure about the location of the valve or cannot safely access it, leave the area immediately and wait for a trained professional to handle the situation.
