How to Safely Store a 100lb Propane Tank Outdoors?

April 5, 2026

Quick Answer

Store a 100lb propane tank outdoors on a level surface, away from direct sunlight and heat sources, and secure it firmly to prevent tipping. Use a protective cover to shield the tank from the elements and consider installing a grounding system to prevent electrical shock.

Choosing a Safe Location

When selecting a location for your 100lb propane tank, look for a spot that is at least 10 feet away from any combustible materials, such as wood or dry leaves. This will help prevent a fire from spreading if there is an accident. Additionally, the area should be well-drained to prevent water from accumulating around the tank, which can lead to corrosion.

Securing the Tank

To prevent the propane tank from tipping over, make sure it is securely anchored to the ground using a tank strap or a grounding system. You can use a 1/4 inch thick steel strap that is at least 3 feet long to secure the tank to a concrete pad or a metal stake. This will help prevent the tank from moving or shifting during strong winds or earthquakes.

Grounding the Tank

Installing a grounding system is an essential safety precaution when storing a propane tank outdoors. This will help prevent electrical shock if there is a lightning strike or a power line accident. You can use a grounding rod that is at least 8 feet long and made of 1/2 inch thick steel to connect the tank to the earth. This will provide a safe path for electricity to flow to the ground, protecting you and your property from harm.
