Maintain a safe LP gas system
Tank conversions could put your customers in danger.
Maintaining the integrity of your customers’ gas systems is the most critical aspect of a liquid propane gas (LP-Gas) handler’s safety program. Compromising an LP-Gas system could cause an uncontrolled release of propane, or worse, an explosion — resulting in extensive property damage and serious bodily injury.
LP-Gas and anhydrous ammonia don’t mix
Among the key risks to any gas system is contamination with anhydrous ammonia (NH3). Similar vapor pressure characteristics of LP-Gas and NH3 can make interchanging or repurposing equipment tempting — but it’s never a good idea. In fact, NFPA 58 states ASME containers of 3000-gal water capacity or less used to store NH3 shall not be converted to LP-Gas fuel service. Nationwide Agribusiness strongly recommends you don’t allow service interchanges on any tank or storage container.
Once present in an LP gas system, NH3 poses the following risks:
- Corrosion to brass and copper fittings
- Increased fire hazard
- Liability exposure
Gasoline doesn’t either
We continue to see alarming cases of LP-Gas containers being converted for gasoline storage and dispensing. This practice is not only extremely dangerous — it’s illegal. The National Fire Protection Association (NFPA) standard clearly states that Class 1 liquids, including gasoline, are never to be pressurized. Pumping gas into a converted LP-Gas tank or any unapproved container is simply against the law.
