Propane is one of the most versatile and efficient fuel sources. It heats homes, powers grills, and does much more. Probably the question on most users’ minds is: Does propane go bad? The answer is no, propane cannot go bad. However, there are important considerations regarding propane storage, tank maintenance, and safety protocols to ensure its effectiveness over time. This article will help you in solving the mystery of whether propane goes bad, dispels common myths, and provides useful information regarding how to store your propane for long term use.
Unlike other types of fuels that may have an expiration date, such as gasoline and kerosene, this doesn’t apply to propane. Because of the chemical stability present, the potency of the chemical can be ensured to maintain without decaying over time should one ensure proper storage. Probably that’s one of the factors, in addition to many others, on account of which propane is ideal to use even for long-duration stockage. Whether in large residential tanks or small portable cylinders, the fuel itself is effective if the tank is sealed and maintained. Thus, propane users can store their fuel without worry of it going bad.
Propane can last indefinitely when stored properly. The limitation lies not with the propane but with the storage tank. Storage tanks have a lifespan based on manufacturing standards and regulatory guidelines.
Small tanks, such as a grill or portable heater small tank, have 12 years life from its production date. After the expiration of 12 years usage these tanks must be requalified in turn that stretches their usage by another 5 years.
Those that supply heat to houses or power appliances last about 25 years, if checked regularly and serviced. Householders usually do not own the domestic propane tanks but have them on lease from a supplier who also checks them regularly and recertifies them.
A date in the form of month-year, such as ‘06-20’ is a date of manufacture or requalification, and is stamped on the ring of the tank.
Propane is stored in a liquid form under pressure. The moment it is released from the tank, it becomes a gas. This is a very good and portable fuel due to this conversion process. On the other hand, propane does not evaporate or disperse unless the tank is sealed and leak-proof. Yet another key characteristic of propane is that it expands and contracts as temperature changes. Filled to only 80%, the tank left with empty space to expand, warmer temperatures cannot over-pressurize it.
One of the attractive qualities about propane is that it is stable. Irrespective of how many weeks, months, or even years one has stored propane, it is still as effective as when it was first filled. Unlike gasoline, propane does not deteriorate or lose its potency with time. You can use it worry-free if you have propane that has been sitting in your tank through many seasons. Still, you will need to inspect the condition of the tank before use.
Propane does not expire, but the tank it lives in has to be checked and maintained periodically. Check for these warning signs that may indicate your tank needs service or perhaps a replacement:
Visible rust or damage on the outer surface of the tank can compromise the integrity over time.
If you notice an odor of gas (propane is odorized for safety), do not use the tank and have it inspected right away.
Always look for the stamped date on the collar of your tank. If it is past its certification period, the tank has to be requalified or replaced.
Faulty valves can cause leaks or even impede the flow of propane.
For propane to be stored safely and operate effectively, safe and appropriate storage procedures must be observed:
Propane tanks must always be kept in an open and well-ventilated area in such a way that gases might not be confined by leakage.
Although propane is relatively stable for a wide range of temperatures, it should be stored away from direct sunlight and extreme heat.
Use soapy water to check for leaks around the valves and connectors. Bubbles indicate a leak.
Store the propane tanks upright to prevent potential damage of the valve or a possible leak.
When your propane tank nears the end of its certification cycle, you have two basic options:
Many retailers have propane tank exchange programs that allow you to exchange your expired tank for a new or requalified one. This is fast, convenient, and guarantees that you’ll always have a safe and ready tank.
Transport it to a certified propane dealer or service provider to have it inspected and requalified for use. Requalification typically costs less than purchasing a new tank; it’s the process of fully testing a tank to meet safety standards, and when passed, receives a new certification stamp that will last for up to five additional years.
If the tank is damaged or cannot be requalified, it needs to be disposed of responsibly. Look up a local recycling center or hazardous waste facility that accepts propane tanks so they can handle the situation safely and responsibly, without any damage to the environment. Do not dispose of an old tank in regular garbage because propane tanks are dangerous, especially if they are pressurized.
You are wrong. Propane is chemically stable in perpetuity.
You are wrong. Proper storage is critical to safety and efficiency.
Not true. The propane itself is fine; it’s the condition of the tank that matters.
