Small Cylinder Transportation

Transporting Small Cylinders

Always transport and store a cylinder in a secure and upright position so it will not fall, shift, or roll.

Always close the cylinder valve and, if required, seal with a plug, even if the cylinder is empty. Ask your retailer if a plug is required

Never keep a filled cylinder inside a hot vehicle or transport it inside a closed trunk.

Always place the cylinder in a well ventilated area of the vehicle.

Always proceed directly to your destination and immediately remove the cylinder from your vehicle.

**The law places limits on the number of cylinders and the amount of propane that can be transported in closed-bodied vehicles such as passenger cars and vans. Ask your retailer for more information on state and local codes the apply to you.

What does Propane smell like?

Propane smells like rotten eggs, a skunk’s spray, or a dead animal. Propane manufacturers add this smell to help alert customers to propane leaks. Some people may have difficulty smelling propane due to their age (older people may have a less sensitive sense of smell); a medical condition; or the effects of medication, alcohol, tobacco, or drugs. Consider purchasing a propane gas detector as an additional measure of security.

Odor Fade
Odor fade is an unintentional reduction in the concentration of the odor of propane, making it more difficult to smell. Although rare, this can be caused by the presence of air, water, or rust in the cylinder. New and reconditioned small cylinders that sit too long before being filled are prone to internal rust when moisture and air get inside.

What is Propane?

Propane (also called LPG – liquefied petroleum gas – or LP Gas) is a liquefied fuel stored under pressure. In most systems, propane is vaporized to a gas before it leaves the cylinder. Propane is flammable when mixed with air (oxygen) and can be ignited by many sources, including open flames, smoking materials, electrical sparks, and static electricity. Severe “freeze burn” or frostbite can result if propane comes in contact with your skin.
