Propane Tank Problems

Propane is a common fuel for backyard barbecues, engines and portable stoves. Interestingly, propane is normally a gas, but when condensed into the container that is commonly seen under a grill, it becomes a liquid. Fortunately, it can be held in containers at a reasonable pressure. This allows for expedited filling time, cheap container construction and a price range that is similar to gasoline.

Containers

• Propane tanks are made of steel and are offered in a variety of sizes based on their use. The smallest tanks are one time use, but the standard size for grilling, as well as the large size for recreation vehicles, are reusable and refillable. The most critical factor of the larger containers is their color, if they are painted a dark color rather than the standard grey or white, the tank will continuously heat until an explosion occurs.

Leaks

• A propane tank leak, often referred to as the tank making a hissing noise, can be caused be a couple different factors. The first issue could be an open bleeder valve, however, once discovered, a simple turn of the valve clockwise will stop the leak. The second cause, relief valve actuation, is the tank letting out excess propane on hot summer days. To stop the leak, simply take the tank to a the shade and spray it down with cold water.

Hoses

• A common propane tank hose is certified to handle small, low pressure tanks from 5 to 40 pounds, the standard weight for tanks of recreational use. Unfortunately, these hoses will age with time, much like the tank. The aging results in cracking out the outer rubber shell, leading to leaks which could potentially cause an explosion. Immediately replace the hose if you see any signs of the exterior becoming dry or cracked.

Rust

• Being outside for the majority of their life, propane tanks are highly susceptible to rusting. Rust is dangerous on a tank because it will pit out the exterior shell, compromising the safety of its structure. If any rust is noticed, immediately paint over the rusted spot with an approved color of paint such as a shade of gray or white.

Disposal

• Although low pressure propane tanks are built to be moved frequently, left outdoors, and refilled many times, tanks still must be disposed of eventually. If you intend to dispense of the old tank yourself rather than trade it in for a new one, there is a proper procedure. Take the tank to a licensed filling station to let their technicians inspect it the tank. If they deem it unfit for refill or use, either let them dispose of it or contact the company the tank was produced by to take care of the useless tank.
